Hi All.
I have created a project and working fine.

Its a UNO with a WTV020-S. The idea is to play a sound thru a 2-way radio but I have to press the button to transmit.

Could I use a relay or such like to replace the button? I know the programming bit but its the electrical bit im stuck with.

Hope this makes sence.
