Commande et mesure de vitesse d’un moteur DC par Arduino avec application androïd

Abstract

The development of technology leading to the use of machines that require precise and variable speeds, for example a high-speed train, the main advantage of DC machines lies in their simple adaptation to the means of adjusting or changing their speed, torque and direction of rotation as well as their direct connection to a power source (vessel batteries, batteries, etc. it) Despite its main problem arising at the level of contact between the brush or "carbon" and the rotary collector, a DC motor can still be used in many applications. In this project, we realized a DC motor control system and also a system that detects the number of revolutions and will convert it to speed and then send it to the Android interface on our smartphone, the motor value is displayed and can be modified by working on the application slider.
