Further, the Arduino Opta can process analog and digital input data. The micro-PLC has eight analog/digital inputs and four electromechanical relays (EMRs). For the project build, one digital input ...

Fortunately, both the speed and direction of a DC motor can be controlled via an Arduino microcontroller. Let’s get into details. Direction control A circuit known as an H-bridge may be used to alter ...

Arduino and L293D Circuit Diagram Now that we have completely understood how the L293D motor driver IC works we can connect all the required wires to the L293d Arduino, and we can write some code to ...

The speed of the DC motor (both directions) is controlled with the 10k potentiometer which is connected to analog channel 0 (A0) and the direction of rotation is controlled with the push button which ...

3) Relay Module: Controls the power supply to the motors, acting as a switch. 4) DC Motors: Provide the driving force for the car. 5) Motor Power Supply: A battery pack or other power source for the ...

Figure 1. Arduino Uno. available to control a DC motor [8]. The Arduino Uno is one of the most common starter boards that are being used to control multiple kinds of motors, especially DC motors, ...
