PWM -DAC LED CONTROL

PWM - DAC LED CONTROL USING ARDUINO MEGA

This is a series of simple projects aimed at getting started with Arduino. This will cover most of the important peripherals of the Arduino starting from simple ADC to DAC using PWM and communication

interfaces etc.

In the first set of projects the following are included. They are basically about the Digital I/Os and ADC USING PWM on the arduino.

1:PWM-DAC LED CONTROL
2:PWM-DAC FAN CONTROL
3:PWM-LDR BRIGHTNESS CONTROL
4:PWM-PROGRAMMABLE VOLTAGE SOURCE

In this we are going to see the experiment

PWM -DAC LED CONTROL:

Connect the poteniometer as a adc input to the pin A0 and a led to the pin 13 and suitable power supply.

when the poteniometer is varied the led brightness gets increases.
