I am making a push button switch board for switching ON or OFF A.C. load.
Please tell which way it be reliable, using RELAYS, TRAICS or SCR...??
Personally I do not want to use relays, so if I use a TRIAC, then how should I connect it to arduino .
Can I connect the GATE of the TRIAC directly to arduino ar I should use a MOC3011 optoisolator..??
For switching light loads, you can use an opto triac such as http://www.farnell.com/datasheets/1244301.pdf. For higher loads, use an SSR - it's easier than making one yourself from a triac.
cjdelphi:
depends on how much you want to use it (switching on/off)
if it's a lot of switching on and off. avoid relays... a solid state relay would be a good alternative for a lot of switching...
out of curiosity, what is you're doing?
I am converting my bedroom electrical switch board to digital. That is , instead of the piano switch I will be using tactile push buttons to switch LIGHTS, FAN and etc. Later in few days I will add a IR sensor and a remote to control them with an IR remote..
