It’s connected to one of the terminals of the motor and it’s is high when input 3 is high else it will be low. (Control signal received from a microcontroller or microprocessor) Output 3 (Pin No. This is an input pin to control the direction of the right motor.
(in short, it enables the right part of the IC ) Input 3 (Pin No. logic 0 or low voltage then the right part of the IC won’t work. This pin is an active-high when it receives high or logic 1 then it enables the right part of the IC and when it receives active low i.e. this voltage used to drive or to run both motors Enable 3-4 (Pin No. (Control signal received from a microcontroller or microprocessor)Ĭonnected to the power supply of range 4.5V to 36V. This is an input pin to control the direction of the left motor. It’s connected to the second terminals of the motor and it’s is high when input 2 is high else it will be low. (because its drive two motors that’s why it has an extra load to compensate that load it has two pins as heat sink otherwise the ic gets overheated and burn out) Output 2 (Pin No. 4 & 5)-:īoth pins are for heat sink and ground pins. It’s connected to one of the terminals of the motor and it’s is high when input 1 is high else it will be low. (Control signal received from a microcontroller or microprocessor) Output 1 (Pin No. (in short, it enablers the left part of the ic) At the end of the pin description, there are two important notes. logic 0 or low voltage then the left part of the ic won’t work. This pin is an active-high when it receives high or logic 1 then it enables the left part of the ic and when it receives active low i.e. The functions of all 16 pins which are mentioned in the above pin diagram of L293D is given below. In this article, we are going to learn about the Pin Diagram of L293D, Functions of pins L293D, Working Principle of L293D, and Interfacing of L293D with Arduino and their code. we can apply 4.5V to 36V at pin 8 and to run the whole IC 5V should be applied at pin 16. Now I’ll explain to you why I had said that it’s magical IC because of its Dual H-Bridge Configuration it can operate over two voltages i.e.
KONFIGURASI PIN ARDUINO UNO DRIVER
also, we can control the speed of the DC motors by applying the PWM signal at Enable pins shown in the pin diagram of L293D of the Motor Driver IC L293D. based on these control signals it controls the direction of rotation of the DC motors. It receives a control signal from microcontrollers such as Arduino, ESP32 Dev Module, etc. L293D can drive two DC motors simultaneously, with up to 600mA current in each channel.
In this blog, we will discuss about L293D Pin Diagram its working, and its interfacing with Arduino.
