Regulating the current of an AC lamp dimmer

In this section, we will see how to regulate an AC lamp. For so many years I've wanted to explain and share a project like this, and I'm finally. This can be applied to regulate your lamps at home in order to decrease domestic power the consumption: the following sections will explain the project in more detail.

Hardware requirements

We need the following electronic components:

• H-bridge

• 24 AC transformer

• Two resistors 22k (1 watt)

• One integrated circuit (4N25)

• One resistor 10k

• One potentiometer of 5k

• One resistor 330 ohms

• One resistor 180 ohms

• One integrated circuit MOC3011

• One TRIAC 2N6073

In the following circuit diagram, we can see the connections for the dimmer from the Arduino board:

Software code

You can now either copy the code inside a file called Dimner.ino, or just get the complete code from the folder for this project:

int load = 10;  
int intensity = 128; 
 
void setup() 
{ 
pinMode(loaf, OUTPUT); 
attachInterrupt(0, cross_zero_int...
