Programming IC + Hex File

Important part is to program the IC.

Use pickit2 or pic serial programmer to code the 'kumir.HEX' file into the IC.

Simple step, if you are in doubt here, give it to some electronics project shop and program it.

Breadboarding

Use schematic and breadboard and feel the output.

Here used LM7824 to get 24VDC for steady driving of the relay.

Here used some spare relays and berg strip replaced by a push switch for testing in breadboard.

Stripboarding

This is totally of soldering skills and the layout is of own taste.

Find the pictures.

Insert jumper and configure for any 3 button on any SONY REMOTE.
3 buttons will be stored in the IC, use it for switching the appliance.
Remove the jumper and use the appliance.

240VAC Circuiting

In order to function in both relay and switch, replace normal SPST switch to SPDT i.e Two way switch, for the appliance.
so when 24V adaptor is switched off the appliance will toggle ON of OFF, so that case it can also be operated by SPDT switch.
