Hello All, I was hoping to get some help on the best way to control a Digital Pin on another Microcontorller using the Arduino...
I have an amplifier module that I would like to be able to control through the computer. The Amplifier has an Enable PIN which is HIGH (+5V) when left unconnected, if the PIN is pulled LOW (GND) it will disable the Amp.
What would be the best way to control this PIN from an Arduino?
Thank you all for your help in advance. Kind Regards, Alex.
