Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

[Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to send (or receive) serial messages, too. This is a neat idea — kind of a simplified Bus Pirate.

Pinout of a 4-pin pushbutton. A switch connects the two pin pairs together. In a way, there are always two pins connected in a pushbutton. When you press the 4-pin pushbutton, you connect all four ...
