Arduino open collector output - Pull-up resistors, high impedance pins, and open collector
Is there any way to have an Arduino Uno pin output 3. 3V instead of 5V when it is high (looking for a non PWM solution)? Use an opencollector configuration.

With the need to drive some electronics with open collector open drain outputs from Arduino, I just realized that it may just.
An open collector is a common type of output found on many integrated circuits (IC), which behaves like a switch that is either connected to ground or disconnected.
