DIY touch wall switch.
In this video, I show how to make a touch wall switch. This DIY project is more suitable for this modern world. The main controller is atmega88. I used the NRF24L01 2.4Ghz transceiver module for future upgrades.
you can download the schematics, PCB and code from this link:

Disclaimer! working with high voltage is risky. Therefore handle it very carefully.
This video shows an idea for a smart home. If you willing to make a device like this, do it with your own risk.
