  • Turning Stereo Amplifer On and Off automatically

    I'm trying to set this up on a Particle Photon as I want something connected to the network and with my limited knowledge of this stuff it seemed like the easiest way to do it. I'm struggling to understand some things here. You said in a comment response that this has one input (from audio source) and one output (to amp) but I don't understand how the circuit diagram can support that as the L and R inputs (A2 and A3) don't connect to the L and R outputs (A4 and A5). There are connections to resistors that are connected to the ground but how can that connect A2 (L in) to A4 (L out) and A3 (R in) to A5 (R out) as they are all connected to the ground through the resistors. Would really appreciate clarification on this. Thank you!
