The code is pretty straightforward.ĭigitalWrite(7,HIGH) //Move motor in clockwise direction Programming the Arduino and DC MotorĪs far as programming is concerned, you need to set a motor to move in a particular direction and assign it a constant speed. But for assigning speed, we will source PWM pulses from Arduino to enable the L293D’s pin. This will tend to move the motor continuously in a particular direction at maximum speed.

Basically what we have done is, we have just applied a positive signal on one pin of the motor and LOW signal to another pin of the motor.

These signals will then be amplified and given to the motor. The L293D can drive two motors at a time and for each motor, it has two input pins (A) and two output pins (Y).Īt one input pin, we have to pass a HIGH digital signal and at other a LOW signal. It requires two Vcc’s: 5V (Vcc1) for its internal driver operation and 12V (Vcc2) for the motor.

Download all library-related files from GitHub. Follow the steps below to install it on your PC.ġ. Proteus doesn’t come with an inbuilt Arduino library, so you have to install it externally. How to Install an Arduino Library in Proteus If you want to work on a cool project which involves some circuit design, I recommend Proteus. If you are a beginner to Arduino and circuit design, then I recommend you try out TinkerCAD. TinkerCAD is also another tool that can be used for simulation.Developed by AutoDesk, it is a cloud-based software which is only limited to Arduino simulation. However, it is not only limited to simulation - you can also make PCB designs with it. I prefer Proteus for Arduino project simulation because of its extensive collection of libraries. The designs you make can be easily compiled and debugged through Proteus’s virtual meters (voltmeter and ammeter), oscilloscope, serial monitor, and more. It has an extensive number of components in its library which can be used to virtually design your circuit. It is a very useful tool as it ensures that the circuit design or firmware code is working properly before you begin to physically work on it. Proteus is a simulation and electronic design development tool developed by Lab Center Electronics. What is Proteus and How Does it Compare to Other Simulation Software?
