I am pretty new to the world of electronic circuits, so here's me newbie question:
I want to build a dimmer for a 220V Light bulb.
I tried this by using an SSR from sharp (the S202SE2
). The SSR is "an integration of an infrared
emitting diode (IRED), a Phototriac Detector and a main output Triac", which seemed good to me.
I connected one side of the SSR to the powered light-bulb, the other side to my Arduino board.
When sending HIGH or LOW voltages, the lights turn on and off, so far so good!
But when I send a PWM signal, the light does dim a little bit, but as pulse width gets smaller, the light starts flickering dramatically instead of dimming...
Do i need things like capacitators or so? As I said, my expertise in electronic circuits is pretty low..
I have seen Massimo's post
, advising to buy the Vellema K8064 dimmer pack, put it seems like a lot of circuits for just dimming one lamp?
What are the basics I need to know about dimming lamps?
Thanks a lot people,
