Infrared proximity sensors are very fun to play with. In the past we have used them to make Digital Theremins and Control Robots, always using its proximity sensing (how far away an object is from the sensor) as the main feature. Today, we’re going on a quest to use an infrared proximity sensor, to control […]

Description There are lots of designs on the Internet for DC power controllers using Pulse Width Modulation (PWM) to control the speed of a motor or power to a resistive load. Most of these use analogue methods to generate the PWM signal which in turn drives a power MOSFET or transistor. When I wanted a

Background From the first robot I ever made, I have always felt that when designing the motors, wheels and drive train, it will almost always be important to know where you are – that is, to have some sort of encoder feedback. So the first robot I built used stepper motors, but I found that

Background There are a number of other projects that have been documented for brushed motor ESCs. The good starting point for other ESCs is this rcgroups thread. The information in the Microchip AN847 is also very useful. Most of these designs are very similar, the variation between designs is typically in the PIC used to

Parallel Port 3 Axis CNC Driver, Opto-Isolated, Unipolar Steppers Controls 3 Unipolar Stepper Motors, for use with CNC Machines. Simple driver with automatic coil shutdown, to ensure efficient operation. Opto-isolated for protection of the P.C. Supports most parallel port based CNC software, such as KCAM. Supports up to 20 watts per Phase. Or 2 Amps
At home I have a few electrical Rolling Shutters that are controlling via a switch with which you can let them go up or down. When the Rolling Shutter reaches the end of its up or down movement, the motor of the Rolling Shutter stops automatically and you can put the switch that controls it

Brief Description: The main goal of this project is to design a DC motor controller, We had a DC motor controller that its control circuit has been damaged. Here we are attempting to design a new control circuit for the controller. But before we can design the control circuit, we needed to know the power
