If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

Wenn die integrierten GPIO-Pins am Arduino, ESP8266, ESP32 oder Raspi nicht reichen, hilft ein per I2C-Bus angeschlossener GPIO-Extender-Chip wie der MCP23017.

A Raspberry Pi Zero Shield that will connect a Zero or Zero W module to a 3.3V or 5V compatible Arduino board, is available from US-based Burgessworld Custom Electronics. The two boards are connected ...

Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

We got it running on an Arduino Leonardo the quickest, because it has support for Serial1(). Don’t be discouraged by these glitches in this rev 0 deployment — [Eric] has really made quite a ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...
