Как подключить к arduino TTL AC 220V Optocoupler Isolation
Why can't I use an optocoupler to drive an AC circuit using the arduino digital pins? Ask Question 1. So, when I searched for ways to drive AC circuits from Arduino, everyone suggested relays with a transistor switching circuit to channel an external 5V. 220 V AC mains I meant – sixter Oct 22 '15 at 8:46. Maximum current is 50mA, so not The post discusses a few interesting and simple delay timer circuits which promises many interesting applications. The design relies only on BJTs and a few resistors and capacitor
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.
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).
DIY Sunrise Alarm Using Arduino T. K. Hareendran - 01/06/19 This is done with the use of the optocoupler IC TIL111 but a suitable replacement can be used too. logic HIGH level signal when the 220 V AC power applies to the input, just “opposite” functionality as presented here. I want to have it in my ventilation fan control circuit

Optocoupler, Phototransistor Output, with Base Connection DESCRIPTION This datasheet presents five families of Vishay industry standard single channel phototransistor couplers. These families include the 4N35, 4N36, 4N37, 4N38 couplers. Each optocoupler consists of gallium arsenide infrared LED and a silicon NPN phototransistor.

The triac is activated when there is a high logic level on the correponding I/O pin, and deactivated when the there is a low logic level on the pin. The triac is activated via an optocoupler and the triac lead that is kept in contact with the heatsink is internally isolated.

Controlling a plug with an arduino. The optocoupler basically consists of a LED and a phototransistor, the two circuits never touches each other. It is a basic LED connection, simply connect the long leg to a arduino's digital output through a 220 Ohm resistor and the short the ground. Now your arduino can already control the plug. With
