Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

PCB pin-headers 5V-GND-RST-10-11-12-13 allows to program the ATtiny85 from an Arduino UNO, instead of Arduino Nano. Remove from PCB any pluged Arduino Nano if you are going to program the ATtiny85 ...

For example, connect Digispark ATtiny85 pin 0 to Arduino Uno pin 11, Digispark ATtiny85 pin 1 to Arduino Uno pin 12, etc. Also connect a 10uF capacitor between arduino RST and arduino GND. Note that ...

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like [ElectroBoy]’s ...
