The transistor-controlled relay mentioned above enables you to switch very large amounts of current on or off. This enables you to switch large devices such as your washer/dryer, heater, air conditioner, car starter, among other things on or off with your Arduino. ...
The transistor Q2, driven by the port 5 of the ATtiny (D0), serves as a switch to enable or disable the LED-1 and the transistor Q1. It’s really important that LED1 is RED, and this is not a matter of aesthetics, but because the power output is given by the ratio between the ...
