I want to control my room ac appliances with my smartphone so I made this minimal setup which uses HC05 to trigger the relay.
At first, I made a Crude relay with Arduino Nano and HC05 setup which was not very practical as it was missing many things including a Power supply that will power it through AC Power.
So I made this ...
Thanks UTSOURCE.net to offer electronic components for this project!
you can check UTSOURCE.net, they deal in all kinds of electronic components, for example, Arduino board, Relay, and many more.
watch the video for old setup.
I reached out to JLCPCB and they supported this project of mine,
now I have finalized it.
my setup contains a minimal atmega328PU setup which is connected with an AC 5V Charger IC circuit which I added for powering this whole board. the AC Charger circuit is based around CT5512 IC.
atmega HIGH/LOW the MOSFETs which is connected with the relay to toggle AC Load.
Ive used an HC01 SMD BT Module to receive serial data over BT to trigger stuff.
