In this article you'll learn how to control the ESP32 and ESP8266 GPIOs with MicroPython: digital inputs, digital outputs, analog inputs, and PWM signals.

After learning how to flash a single LED on your Arduino, you are probably looking for a way to make cool patterns, but feel limited by the use of delay(). If you ask in the forums, you get told to look at the “Blink Without Delay” example. This example introduces…

Security is increasingly something EEs need to be cognizant of in their component choices. Here's an overview of three secure microcontrollers.

AVR-HV2 is an Arduino-based high voltage parallel programmer for AVR microcontrollers.

Start converging between microcontroller dev boards and FPGA dev boards by running Adafruit's CircuitPython on the Zynqberry for the PiOLED.

Doing tiny machine learning on even tinier processors.

I am obsessed with creating the quickest soldering station ever. If a sports car can go from 0 to 60 in less than 3 seconds, I want my soldering iron to go from 25*C to 400 in 2 seconds. Between picking it up from the stand and touching its tip to the PCB…

LED Distance Indicator Dog Harness: I usually take my dog Rusio for a walk when the sun goes down so he can play without getting too hot. The problem is that when he's off the leash sometimes he gets too excited and runs further than he should and with the…

Water/Feed Level Indicators: In this instructable I'll show you how I made a water level indicator without the use of micro processors, micro controllers, Raspberry Pi, Arduino etc. When it comes to electronics, I'm a complete "dummy". I do use some electronic…

Use a Stepper Motor As a Rotary Encoder: Rotary encoders are great for use in microcontroller projects as an input device but their performance is not very smooth and satisfactory. Also, having a lot of spare stepper motors around, I decided to give them…

Mini Oscilloscope: This is an Instructable about a mini oscilloscope I made, it isn't anywhere near as capable as a real (digital) oscilloscope (such as my Rigol) but I think it is nice to have. Even more important, I enjoy making things, even when they have…

3D Printed Arduino Based RC Transmitter: This project will show you how I went about designing and building an Arduino based RC Transmitter.My goal for this project was to design a 3D printable RC Transmitter that I could use to control other Arduino projects.…

Automated Perpetual Calendar: Years ago I came across a wooden perpetual calendar and I loved the idea. After thinking about it for months I decided I wanted to make one myself; however, there was a long list of things I wanted to do to improve on the idea.…

You've got secrets, and you want to keep them safe? Most microcontrollers are not designed to protect against snoopers, but a crypto-authentication chip can be used to lock away private ...

Aquí un podcast con German y José Manuel. Se habla sobre las cualidades de la Raspberry Pi Pico, una solución a "memory leak" y 🎙️ audio en streaming con Raspi

Designed to offer the best of the FPGA and microcontroller worlds, the Kiwi is heading to crowdfunding site Crowd Supply soon.

XOD-powered Rechargeable Solar Lamp: There are inexpensive solar garden/walkway lamps available at most home goods and hardware stores. But as the old saying goes, you usually get what you pay for. The usual charging and illumination circuits they use are…
