My son wanted to turn his HotWheels garage into a water ride ? the little one has now understood the causality of water and electrics but his crocodile tears have softened my heart and I said: "I'll see what I can do" I'm not a professional but I understand the connections, know the difference between plus and minus and can handle a soldering iron. The only question is what is the best way to proceed? I think it only fried the speaker, but I don't want to put unnecessary current on it now and possibly damage more. Should I wait a bit and then clean everything with isopropyl alcohol? Or can I ..read more

I have a project of interfacing BME280 sensor with raspberry pi pico through SPI protocol .I have done it through I2C protocol but I want to communicate through SPI protocol .Please tell me how to communicate through SPI protocol submitted by /u/Some_Finish_2511 [visit reddit] [comments ..read more

Hey everyone! I made a tutorial on how to get angles from the MPU6050 and animate the orientation of the device on a screen in 3D, cool project for beginners. Check it out again here: https://m.youtube.com/watch?v=rHy3D52AkbM This project uses Processing (open-source!) alongside the toxiclibs library. You'll just need an MPU6050 sensor and an Arduino-compatible board. I used an ESP32, but any Arduino board should work! Speaking of subscribing, thanks to all of you amazing viewers, we've CRUSHED the 2,000 subscriber mark! If you haven't already, hit that subscribe button to keep up with all th ..read more

I'm a drummer, and for the past months I've been really into electronic drums. I'm trying to make one myself, but it has been really challenging for me to learn what kind of path I need to take for this. I need an MCU to convert multiple (Sometimes even simultaneous) analog signals into MIDI, and forward it to my computer so that the rest of the magic can be done there. But I'm not sure about which MCU to use. I've been considering STM32, but I can't really find the resources that I need, and it just seems too complicated for a beginner like me. Arduino is also a candidate (which I've started ..read more

Hello everyone, I'm working on this project and trying to drive a non-I2C LCD. This (https://circuitdigest.com/microcontroller-projects/how-to-interface-16x2-lcd-with-tiva-c-series-tm4c123g-launchpad) really had me going until I saw that a include used, LiquidCrystal.h, referenced other headers, referenced other headers... ad nauseum. LiquidCrystal was apparently meant for Energia (https://github.com/energia/Energia) and I was using Keil. I tried adding the first few, but then I got weird errors like "unknown type class" which I found later was caused by my using c for my main code. Anyway, i ..read more

The Raspberry Pi Pico and Pico W can be used to write files to your local computer using Serial communication. This can be easily accomplished with a basic Python script on your PC, and then by implementing a simple MicroPython script on your Pico or Pico W. This feature is especially useful for storing large amounts of data from sensors, which is a typical use for this microcontroller. It also facilitates the smooth transmission of existing files. For a detailed tutorial and to access the code, check out my YouTube video linked here ⬇️ https://www.youtube.com/watch?v=OfJ5Y1FlW9 If you apprec ..read more

hi all i building a distrobutied BMS and would like a ultra low power MCU for the cell moduels the resuqerments are min voltage 1.5v (lower if possable) max voltage 5v (if possable if not just as high as possable) run current 100ua (less if possable) sleep current as low as possable must have minium of 8 ADC channles nust have a min of 1 UART must have a min of 1 I2C must have min 10 aditional GIPO smallest posable package size submitted by /u/Efficient-Economy-18 [visit reddit] [comments ..read more

This might be a long post, but in short: looking for advice on how to address my knowledge gaps and what are potential future job pathways I got into MCU's nearly a decade ago during an undergraduate course using the TI MSP430. It was introductory and covered timers and PWM. Then, I didn't touch MCUs for years until my PhD came about. I realized they could be used to address a research question we had. For the past 3+ years, 80% of my work has focused on building this MCU based system. The work has been completely done in the Arduino environment, and evolved across a number of boards/chips: A ..read more
