I am new here and would like some help please.
I am switching 2 power heads (220ac) with a Uno R3 I have a 2n35 switching a n Channel mosfet witch interns switches a 12V relay. The cuircut works fine but after about 20 min my lcd goes blank but the controller still runs fine. The only way to get the lcd up is to rest the unit. If I remove the relay connections the uno runs fine as i have it monitoring the room temp. Is there any ideas or an alternitive option to my problem?
Do I need to change the n Channel for a tric ?
