PWM-DAC FAN CONTROL

PWM-DAC FAN 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 FAN CONTROL :

connect a LM35 sensor as a analog input to the pin A0 and connect a fan as output to the pin 13 and suitable power supply 5v . when the temperature increases the fan gets turn on else the fan gets off.
