Learn how to use the Arduino voltage sensor module

Connect ground to your breadboard through the Arduino. Place the optocoupler on your breadboard so that it straddles the center of the board. Connect pin 1 on the optocoupler to Arduino pin 2 in series with a 220-ohm resistor (remember, you are powering an LED inside, you do not want to burn it out). Connect pin 2 of the optocoupler to ground.

Triac - AC grid power control using Triac - Arduino

If you use a different optocoupler than the SHARP PC817 you may need to adjust this resistor to compensate, the PC817 has a Max led input voltage of 1. 4 volts and the resistor brings the arduino 5 volts down to 1. 25 volts. .

The optocoupler (MOC302x) is used for firing the BT136 triac, its LED is connected to Arduino pin 8 through 120 ohm resistor. I chose the value 120 ohm in order to get a current of about 30mA (current passes through the optocoupler LED).

/14/2014I am currently in the process of having an arduino switch a well pump on and off. I already built a standalone ATMega168 board for this, and wrote the code. is halfwave rectify the 220V AC signal and use a capacitor to 'smooth' out the signal and put that into an optocoupler. (I have a few LTV817's around).
