PWM-PROGRAMMABLE COLTAGE SOURCE 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-PROGRAMMABLE VOLTAGE SOURCE :

Connect a capacitor and a resistor to the pin 9 and send a voltage from the pc and the value should be same when it is measured by the multimeter in the circuit.
