![]() ![]() Make the connections of Fig1 on your Pic protoboard 2. Apply your program to the Pic16F877A and check whether your program operates properly.Įxperimental Work: 1. If the user send 0, then turn the motor on bacward direction. If the user send 1, turn the motor on forward direction. Write a MikroC program to perform the following functions: Control the speed of the motor according the to the pot voltage by using the PWM signal applied to the Enable1 input Change the direction of rotation using uart communication. Make the connections of the circuit diagram given in Fig1 using the Proteus simulator. Study and understand the principles of operation of the L293 DC motor driver IC, using the information given above and the data sheet of L293 given in the attached pdf document. The Motor rotates in the forward direction when IN1 = 1 and IN2 = 0 The Motor rotates in the forward direction when IN1 = 0 and IN2 = 1 The speed of the motor is controlled by applying a PWM signal to the Enable (EN1) input Experimental Materials: = 1. This device is a very practical alternative for the complicated H-Bridge motor control circuits and it is suitable for use in switching applications at frequencies up to 5 kHz. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. To simplify use as two bridges each pair of channels is equipped with an enable input. Background Information: L293 is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoids, DC and stepping motors) and switching power transistors. This control system will be constructed both using the Proteus Simulator and also the Pic Protoboard. ![]() A Pic 16F877A microcontroller based DC motor speed and direction control system will be designed and implemented using the L293 driver IC. ![]() Transcribed image text: DC Motor Speed and Direction Control Using the L293 Driver IC Purpose: The purpose of this experiment is to learn the characteristcs and principles of operation of the L293 DC Motor driver IC. ![]()
