Part 2 of my touch switch design. In this video I show the changes I have made from part 1, I have replaced the 555 timer IC with a Pic Microcontroller. I have also added a SMPS and switching a mains powered lamp from a relay. the system now has two forms of operation; toggle and timed. I also show you schematic of the new circuit and PCB layout. The software i'm using is Altium designer
