What happens when you combine an Arduino-based microcontroller with a palm-sized aluminum box and clicky buttons? A fidget ...

Have you heard the saying “the problem is the solution”? It seems to originate in the permaculture movement, but it can apply equally well to electronics. Take the problem [shiura] ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...

This library currently supports any board based on the ATmega168, ATmega328P, ATmega32U4, or ATmega2560 which runs at 8 MHz, 16 MHz, or 20 MHz. The LED strip's input connector has two pins that should ...

Additional circuitry required. One Diode (I use 1n4004) - pole/cathode at tx pin other at rx pin. 4k7 Ohm resistor between rx and 5V (3.3V also works). Same at the other microcontroller but you don't ...
