A complete project and of corse high quality work....but i am searching for a complete schematic of a imput selector with relays...could you post the schematic here with the components value and detail...thanks
The schematics of the input selector can be found here. There you will also find the circuit board drawing. I have changed it a bit and added more relays for a balanced input. You need an additional 5V power supply and a signal from a microcontroller to operate the relays. I have combined this with the volume remote control.
Parts involved: relay: Massuse Reed Relay, SIP type, MES 1A05, gives an RC of 500 Ohm, transistor: BC 337- 25, Rb 13KOhm.
When you operate the boards there will be the need to have an indicator that tells you which input is selected at the moment. See my schematic of the LED indicator below. Please note that you can switch inputs with your remote control only.
