Hello,
I am doing this project that measures AC current and then displays it on a 16X2 LCD. Everything works fine except that when I toggle the switch to turn the load on or off, the LCD display starts to show random characters or just disappears. I faced this problem once before when I was working on a Power line communication project. This thing happened there as well. It also involved AC interaction with the circuit. I have searched the web but didn't find any relevant solutions. I should mention that I am using a relay but that isn't the reason why the LCD is malfunctioning. It only happens when I switch the load (which in this case is a 100 Watt light bulb).
Any help of any sort would be highly appreciated.
Thank you.
