Cytron MD30C R2 5-30V 30A DC Motor Driver

Power

• Plus(+)/ Minus(-): Connect it to a battery (5V to 30V DC)
• GND: Connect it to arduino board ground.
• Terminal A and B: Connect to Motor

---

Signal

Connections for Arduino UNO

• PWM: Connect it to pin D3
• DIR: Connect it to pin D4

---

Code

Before we move into coding, first we need to install the Cytron Motor Drivers Library written by Cytron Technologies in the Arduino IDE. 

You can install this library by directly going to Tools > Manage Libraries which opens the Library Manager. In the library manager search for Cytron Motor Drivers Library using the search bar and click on the install button to install the latest version of the library.

After installtion go to File > Examples > Cytron Motor Drivers Library > select any one example.

We are using the example "PWM_DIR" from the example menu for the code below.

 ********************************************************************************
 * DESCRIPTION:
 *
 * This example shows how to drive a motor using the PWM and DIR pins.
 * This example only shows how to drive a single motor for simplicity.
 * For dual channel motor driver, both channel work the same way.
 * 
 * 
 * CONNECTIONS:
 * 
 * Arduino D3  - Motor Driver PWM Input
 * Arduino D4  - Motor Driver DIR Input
 * Arduino GND - Motor Driver GND
