Motor Driver

01 Dec: Peak Current vs Continuous/Rated Current

Introduction - Important Vocabulary Peak current Continuous current Current when motor starts moving from stationary or when changing direction. Current that is supplied continuously while the motor is running, regardless if motor is loaded or not loaded. This condition usually happen for just a short while and will not cause any damage to the motor driver. The motor driver must be able to withstand the continuous heat dissipated from the MOSFET for a long period...
Espresso Lite V2.0

06 Sep: Smartphone Controlled Wheel Robot

ESPresso Lite V2.0 is a Wi-Fi development board based on the ESP8266 chipset that also supports the Arduino environment. With this board, users can build systems capable of transferring data wirelessly through internet. In this tutorial, we will demonstrate a method of controlling geared DC motors' rotation with MQTT Websockets Panel to create a wheeled robot. The command entered on the panel will commands the robot to move in the desired direction. Our robot uses...

26 Jul: Raspberry Pi: Control DC Motor using MDDS10

There are several methods to control DC motors using Raspberry Pi. The suitable method for your application depends on how many PWM outputs you have and what performance you expect out of those outputs. There is only one hardware PWM output on the Raspberry Pi, so it difficult to control two DC Motor simultaneously. In this tutorial, we will use software PWM method to control 2 DC motors. There are some updates in RPi.GPIO of...
