PWM-LDR BRIGHTNESS CONTROL
PWM-LDR BRIGHTNESS 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
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-LDR BRIGHTNESS CONTROL:
connect a ldr as a analog input to the pin A0 and a led to the pin 13 and power supply 5v.
when the room becomes dark the brightness of the led varies.
