Hi
I have a problem with my circuit. I have a 2 digit display and showing on this temperature from LM35.
Also I want to drive a TRiac with non zer crossing opto and also i have a circuit with zero cross detection connected to pin 2 arduino. Device working fine without sevenSeg library but I need it to show temp on a display.
the problem is when I power up with mains 240V so I display is blinking like multiplex freq in that library changed and cannot see anything.
PLEASE HELP
Code without library that works?
Code with library that doesn't work?
Schematic?
Picture?
We cannot see anything, either.
Please read this carefully.
yes code without library works.
I attached code and last I added ISR and timer 2 but doesn't work
