Back in school, I spent more hours than I can count hunched over an Arduino Uno – blinking LEDs, wiring up sensors, and building clunky robots that barely worked but felt like magic. The Uno was ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...

Raspberry Pi Pico microcontrollers come with a variety of different features for a few bucks, and a few interesting ...

Welcome to the Basic Arduino Projects repository! This project contains a collection of beginner-friendly Arduino circuits simulated using Tinkercad Circuits. It is intended for students, hobbyists, ...

Description: Using an Arduino or a micro controller, we can generate cool-looking patterns with an led strip containing addressable LEDs. In this case, I'm using an Arduino uno (clone board) and a ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source ...

This repo demonstrates how to work with an Arduino's PWM outputs in a clean programmer-friendly way. It packages all the low-level interaction with timer clocks that underly PWM functionality, ...

Abstract: A 9-bit sweep driver is proposed, enabling 240 Hz frame rate of a 4.5-inch active-matrix Micro-LED display with 160 × 90 resolution via analog pulse-width modulation (APWM). This sweep ...
