Hi there all,
I have a project for driving 40W 120V AC lamps with the means of a digital clock's LED voltages of 1.7V DC. I had Sharp S202S02 relays for this purpose. The problem is about the digital clock that I've used. It has a strobe effect in 7 segment LEDs, like multiplexed drive. I got my AC lamps driven like 20Hz or something flickering, that I discovered in the LED's voltage measurement. It was changing all the time when the lamps are to be turned on and off. I need 0V DC while the LEDs are turned off.
My question is: where can I find such a non-multiplexed digital clock?
Any help would be appreciated..
Thanks
Burak.
