Dc motor speed control using pic microcontroller

Hello friends, hope you all are fine and having fun with your lives. Instead this tutorial is written by one of my very good friend Salah Dahouathi. We had an interaction through his awesome . In our robotics applications we may have to control the speed of the DC Motor. By using PWM we can easily control the average .

We can drive two DC Motors with one L293 in this example we are using only the first pair of drivers to drive one DC Motor.

First pair of drivers are enabled by connecting ENto Logic HIGH.

INand INare connected to RBand RBof PIC Microcontroller respectively which are used to provide control signal to the DC . Speed Control of DC Motor using. There are numerous ways to control the speed of motor(or fan). Varying current, voltage and resistance etc.

But when it comes to controlling the speed using microcontrollers.

Then the PWM (Pulse width modulation) . How to control speed of dc motor using pulse width moduation and duty cycle, how to change speed using varia. DC motor speed control using pic microontroller? In our last PIC online tutorial we have covered PWM generation using PIC Microcontroller. Load Control Energy Meter Reading System Using PIC . This project uses the above principle to control the speed of the motor by varying the duty cycle of the pulse applied to it popularly known as PWM control.

A PIC microcontroller is used to deliver the PWM pulses to . In this chapter, dc motor interfacing with PIC microcontroller is described in detail.

But for using it in both directions, we need to use H-bridge driver IC like L293D. The L293D can provide bidirectional drive currents of up to 600mA at voltages from 4. In both ICs, drivers are enabled in pairs with drivers 1 . The purpose of designing this system was to convince the user that speed of the motor can be . To achieve this, PWM technique is use which is in -built under CCP module of PIC. A PIC based speed control scheme has been develope in which L293D is used as an interface between motor and .
