What do you need to build an Arduino Speed Sensor Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very simple ...

Let us move to the Components Assembly of Arduino DC Motor Speed Control. Arduino DC Motor Speed Controller - Hardware Setup Moving on to component assembly, since our circuit is very simple, we used ...

As shown in the circuit diagram we need only 3 Arduino terminal pins, pin 8 is for the push button which toggles the motor direction of rotation. Pins 9 and 10 are PWM signal outputs, at any time ...

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, ...

THEORY The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM outputs from the Arduino we can easily control the speed as well as the direction of ...
