That's a $4 serial / i2c LCD screen soldered directly to what's likely an Arduino based microcontroller - you can see it peeking out on both sides from behind. I have one of those screens and got it working easily enough with an Arduino. If someone knew how to read the battery data with an Arduino, it would be near trivial to replicate. Sorry, I guess I didn't phrase that well. I'm curious if anyone knows the protocol that it uses (maybe I2C or SPI?). I just got my first oscilloscope, so I'll have to play around and see if I can figure anything out. If someone can figure that out, I can create the code to read and display the data.Sent from my iPhone using Tapatalk #11 Sorry, I guess I didn't phrase that well.

Bottom Line: You can use your Macbook Pro’s sound card as an oscilloscope!DisclaimerThis could possibly be unsafe and result in damage to your computer or your health. I don’t know what I’m doing with electronics, I’m a total beginner, so you probably shouldn’t believe anything I write here without verification from a more credible source. Please see my formal(ish) disclaimer for more info.IntroductionWith that out of the way, I’m super pumped to say that I successfully used my Macbook Pro and a 433 MHz receiver as an oscilloscope to analyze the RF signal from a remote control for these inexpensive outlets. Having done so, I was able to replicate the RF signal and control the outlets programmatically from my Arduino! I imagine it will be equally easy to get them working from my Raspberry Pi, which will probably be the end goal.An oscilloscope is basically a tool to help you measure voltage over time. Recognizing that many types of electronics communicate with each other essentially by sending “high” and “low” voltage signals in certain sequences and for certain durations of time, the oscilloscope helps us capture and record those signals.A microphone is basically a device that turns sound waves into electrical signals, which then go to your computer’s sound card for interpretation. Because the sound card is already a device that does a great job with high frequency electrical signals, it’s a great candidate to act as a basic oscilloscope. I had read several posts on how others had used their sound cards as oscilloscopes (sources at the end), but I decided to write my own post on the process because: I’ve never heard of anyone doing it on a Macbook Pro. I ended up going with a setup that was quite a bit simpler than others have reported (though possibly less safe for that reason). I’m amazed that it worked.Equipment I ended up using: 2009 Macbook Pro Stereo audio splitter cable 1 x 10k Ω resistorSetupFor the project I was interested in, I first purchased a 433 MHz RF receiver (since the outlets I’d purchased used that frequency). Luckily, I scored an affordable kit that also had a transmitter. I used my Arduino just to provide power / ground for the receiver unit, since I didn’t have another 5v power source set up.Receiver:Transmitter:Once power and ground were wired to the Arduino, I connected a wire to the data pin on the receiver. I connected up my multimeter between this wire and ground, and then powered up the Arduino. Once everything was on, I clicked the button on the RF remote a few times to see how high the voltage was getting up to on the data pin. (Note that there are 2 data pins — I picked one arbitrarily, I’m not sure why there are two.) I planned on connecting this pin to my MBP, and I’ve read that you should have no higher than 1 volt input.Luckily the voltage was pretty low, but it was hard to tell.

I also have an extended ground cable on the probe, which should be shortened for better signal capture. None the less, I hope that this is still demonstrative of the SparkFun Clock Generator capabilities. SparkFun Clock Generator 5P49V60 Arduino Library Note: This examples below assume you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.If you're using the RedBoard Qwiic and have never connected a CH340 device to your computer before, you may need to install drivers for the USB-to-serial converter. Check out our section on How to Install CH340 Drivers for help with the installationWe've written an Arduino library to make it even easier to get started with the SparkFun Clock Generator 5P49V60. The library will give you its' full functionality and provides example code for 90% of the SparkFun Clock Generator's capabilites. You can obtain the library through the Arduino Library Manager by searching SparkFun Clock Generator or you can download the ZIP file below from its GitHub repository to manually install it. Example 1: Generate a Clock Signal The first example demonstrates the very basics of the SparkFun Clock Generator: how to generate a clock signal. With the Arduino library installed, click on File > Examples > SparkFun Clock 5P49V60 Arduino Library > Example1_generate clock to follow along with this example. At the top of the example code, the correct library is imported and the microcontroller connects to the SparkFun Clock Generator over the default I2C address: 0x6A.language:c#include #include "SparkFun_5P49V60.h"// Uses default address at 0x6A, alternate available at 0x68SparkFun_5P49V60 clockGen;void setup(){ Wire.begin(); Serial.begin(115200); if (clockGen.begin() == true){ Serial.println("Clock Generator Ready."); } else { Serial.println("Could not communicate with the SparkFun Clock Generator."); while(1); }After connecting to the SparkFun Clock Generator, the internal clock frequency of the voltage controlled oscillator is set to 1600MHz (1.6GHz). This frequency can

Introduction: Two Axis CNCI built this two axis cnc-machine to use as a lazer-engraver. I'm waiting for the lazer at the moment, so this insutructable will be continued. For The first time I would like to show you how I wired all my components.Step 1: HardwareFor the power supply, I use an old PC-Power-Supply with 16A. For the wiring I use 0.125mm (5V) and 1.5mm (12V 6A) cooper braid. The wiring is easy and done fast. The hardest part was to shield the wires from the motors. This was done by using aluminum foil around the wires and to insert an RC-Low-Pass-Filter between my limit switches and the input pins of the Arduino. RC-Low-Pass-FilterThis sounds way more complicated than it is. Its just a resistor and a capacitor. Because I use grl, I can use the pull-up-pin-mode to get the resistor, so I just needed a capacitor. Grbl is using pull-up-pin-mode because this causes less distortion for the switches. That means, the switches do not forward +5V, they forward GND and the pins are pulled down from 5V to GND by triggering the switches. This capacitor should be something between 10uF and 0.47uF depending on the distortion. In my case I use a .47uF (50V) for the Y-axis and a 1uF (50V) for the X-axis. These small capacitors a polarised, so watch out to connect the GND part to GND, and plus to the limit-switch and the input pin. This RC-Low-Pass-Filter filters our the signals with high frequency. So just low frequencies can pass through. That means your limit-switch signal is slower (you can not recognise without oscilloscope), but you do not read the distortion.Step 2: SoftwareI use the grbl library to control the Arduino with simple G-Code. InstallationDownload all the code from github/grbl.Download the config.h file I added underneath.Replace the config.h in grbl/grbl with my file (I used the file from MichielD99 and adjusted it to work properly with 2-axis)Pack the grbl folder (which is including the config.h file) to a ZIP-file.Goto your Arduino ide.Add the ZIP-file to the Arduino libraries.Remove the whole code of your sketch.Include the grbl

Contributors: Elias The Sparkiest Favorited Favorite 2 Introduction The SparkFun Clock Generator 5P49V60 breakout board offers a wide range of customizable frequencies in a wide range of different signal types using a single reference clock. Four (single output) clock outputs can generate frequencies from 1MHz-200MHz and eight (differential output) clock outputs can generate frequencies from 1MHz-350MHz. The frequency's many properties can be manipulated in code via I2C using the SparkFun Arduino Library. The SparkFun Clock Generator also has four banks of programmable memory for the time when it's ready to sit on its' own within the project without a microcontroller. This hookup guide will go over all of the many available functions of the SparkFun Clock Generator and gives the hardware rundown on what exactly is on this board. Retired Required MaterialsTo follow along with this tutorial, you will need the following materials. You may not need everything though depending on what you have. For example, I chose the RedBoard Qwiic as a simple demo, but you could use any microcontroller. Add it to your cart, read through the guide, and adjust the cart as necessary.Required ToolsAn oscilloscope is highly recommended to verify that the programmed clock signal is correct as its the only way to verify the output accurately. SparkFun only has a few oscilloscopes in its' catalog, but if it's time to add this essential Electrical Engineering tool to your work bench, then check out SparkFun's offerings below. You will also need to have a soldering iron to connect to the clock output pins! Retired Retired Digital Storage Oscilloscope - 100MHz (TBS2104) TOL-14925 Retired Suggested ReadingIf you aren't familiar with the Qwiic system, we recommend reading here for an overview.We would also recommend taking a look at the following tutorials if you aren't familiar with them. In particular the tutorial on how to use an oscilloscopes might be very helpful depending on your experience.

Oscilloscope in a Matchbox - Arduino

Then be fed to the frequency output dividers of the clock outputs. This is done with clockGen.muxPlltoFodOne() which tells the IC to send the VCO frequency to the frequency output divider of clock one. Next the output mode is set to LVPECL_MODE (low voltage positive emitter coupled logic) with clockGen.clockOneConfigMode(LVPECL_MODE).language:c // Fist, Setting the internal oscillator to a known value. Serial.println("Setting Internal Clock Frequency to 1600MHz."); clockGen.setVcoFrequency(1600.0); // Give float value in MHz. // Clock One ----------------------------------------------------- // Use internal phase lock loop for clock output calculation. clockGen.muxPllToFodOne(); Serial.println("Setting Output Mode to LVPECL."); // There are many OUTPUT modes available for each clock - this example uses // LVPECL (Low voltage Positive Emitter Coupled Logic) mode. clockGen.clockOneConfigMode(LVPECL_MODE);Finally, the frequency is set to 16MHz by giving a float value of 16.0 to the clockGen.setClockOneFreq() function.language:c Serial.println("Setting Clock One Frequency to 16MHz."); clockGen.setClockOneFreq(16.0); // Give float value in MHz, 16.0 = 16000000Hz or 16MHz // --------------------------------------------------------------}void loop(){ delay(1000);}If you have not already, make sure to select the board (in this case the Arduino/Genuino Uno) and COM port. Then hit the upload button. Connecting the output to an oscilloscope, you should see a waveform similar to the output below when in LVPECL mode. If you decide to use a different mode, make sure to adjust the parameter in clockGen.clockOneConfigMode() and its hardware termination. Example 2: Generate Multiple Clocks This example does exactly what the first example does but demonstrates how to also turn on other clock outputs. Click on File > Examples > SparkFun Clock 5P49V60 Arduino Library > Example2_generate_multiple_clocks. This example reinforces how the voltage controlled oscillator frequency is piped to each of the frequency output dividers of the clocks. This doesn't always have to be the case, you can pipe the output of the frequency output divider of one clock to a different output divider to get lower frequencies! Remember that 1MHz is the lowest possible output (clock output frequencies) of any of the frequency output dividers, unless you use this method.
