Interfacing DC Motor with PIC Microcontroller; In this example project DC Motor is interfaced with PIC Microcontroller using L293D Motor Driver. Two Push Button switches are provided to control the speed of the motor. Here we are using 12V DC Motor and average DC value delivered to motor can be varied by varying the duty ratio of the PWM This tutorial is about dc motor speed control with a pic microcontroller using the PWM method. There are many applications of DC motors, where we need a variable speed of DC motor. For example, it has applications in electric cars, trucks, and aircraft. These are three examples where we need variable speed I wanted to know what device can be used in order to light up and control the intensity of several 60Watt bulbs using a microcontroller. Obviously the microcontroller will only be used to control the switching of the bulbs and controlling the firing angle and the bulbs would be getting their power from Main 220V AC

Earlier, we have already seen how to control the speed of DC motor using PWM without Microcontroller. Here, we do the same experiment by using a microcontroller. For that purpose, here we will use 8051 controller to produce PWM wave. By varying the width of this PWM wave, we can control the speed of DC motor So in this simple project 10 V LED light bulb is used. Its intensity is varied using PWM. PWM is generated using AVR micro controller ATMega16. Three push buttons are given to ON/OFF LED bulb and to increase / decrease its intensity. ATMega16 micro controller has built in 4 PWM channels. Out of these four one channel is used to vary intensity.

All you need to do, is connect the two wires + and - of the DC 12V LED Bulb with the + and - terminals of the 12V battery. But, what if you need to run these DC 12V LED Bulbs on 220 Vac The input side of the opto *MUST* use the PIC ground track. You must minimise the loop area of the relay coil circuit. Keep the ground return track for the relay close to and as far as practical, parallel to the +12V track for the relay.

A 12V battery may need a 12V DC wall adapter, or a 12V battery. The ground of the motor power supply should connect to the ground of the microcontroller, on the breadboard. Add a 1N400x power diode in parallel with the collector and emitter of the transistor, pointing away from ground 12V Microcontroller I know of no-one making 12v micro's. The point of micro's going to lower voltages is that as circuit density rises in the core, power dissipation becomes a problem. P=VI, so a 12v micro would create 4x the heat of a 3.3v everything else equal, you would also need non standard voltage interface chips As today world completely depends on the power saving, this prototype will help to decrease the power consumption. Here we are using this circuit for today's world to control AC 60W bulb using 8-bit microcontroller and we are using the concept of pwm (pulse width modulation) technique to control the 60W load by which we can decrease the light intensity and thus power consumption of the load.
