The speed of a DC motor is directly proportional to the voltage applied across its terminals, When the voltage across the motor terminal is varied, then the speed also gets varied accordingly. So this is the main principle of this project. A keyboard is connected to the Raspberry pi board to run the motor at different speeds by pressing the key.According to the program, the PWM (pulse width modulation) is caused at the output, and it can be programmed by using PHP/wiring pi. Depending on the duty cycle, the average current and voltage change, so the speed of the DC motor will also change. A motor driver IC is interfaced to the board for receiving PWM signals and sending desired O/P to the DC motor.Auto Intensity control of Street lights by using Raspberry PiThe main goal of this project is designed to control auto intensity of street lights using Raspberry pi.Hardware and Software RequirementsTransformer, Diodes, Capacitors, Resistors, LEDs, Raspberry pi board, TV or PC monitor, White LEDs, MOSFET, Crystal, PHP program or Wiring PiThis  project uses a bunch of LEDs as street lights which consume less power, and lifetime of the LEDs is also more when compared to the HID lamps. A raspberry pi is used to control the intensity by developing pulse width modulation signals that drive a MOSFET to switch the LEDs to attain desired operation.The intensity of LEDs progressively varies from evening to next day morning, particularly during the peak hours, with full light intensity and then , the decreasing lights’ intensity slowly reduced.
