Digital DC Power supply using PWM with PIC microcontroller

In our lab I saw many DC power supply which have a variable knob to regulate the output. I was dreaming to make such a project where I can regulate the voltage using push button.As I am not an industrial level expert so this project is just about a digital DC power supply of small range(5V-12V). You can press push buttons to increase or decrease output voltage.Here we use LM317 to regulate the output voltag ...

DC motor and Fan speed control using pic 16f877 Microcontroller

Here is a simple project on how to control fan or dc motor speed uisng pic 16f877 microcontroller. There are numerous ways to control the speed of motor(or fan). Varing current,voltage and resistance etc. But when it comes to controlling the speed using microcontrollers. Then the PWM(Pulse width modulation) technique is used. In Pulse width modulation the digital signal high and low time is chaged. Actually ...
