Here is a simple project on how to control fan or dc motor speed uisng pic 16f877 microcontroller. There are numerous ways to control the speed of motor(or fan). Varing current,voltage and resistance etc. But when it comes to controlling the speed using microcontrollers. Then the PWM(Pulse width modulation) technique is used. In Pulse width …

Introduction Controlled by a PIC 32, the automated ice cream topper stores individual ice cream topping preferences, outputting the user’s ideal solid, liquid, and whip cream topping amount with the push of a button. Our project demo can be viewed here:Ā Project Demo. The automatic ice cream topper as demoed had three basic topping capabilities that …
Introduction For our final project we built a dynamometer that measures various performance characteristics of small electric motors, such as torque, rpm and efficiency. The final goal was to be able to produce a motor efficiency map like this one, but for this class project the goal was just to get everything designed and functioning: …
Introduction When sailing a boat, one of the most important factors is the direction of the wind. If they want to keep a steady heading, sailors need to be able to dynamically adjust the direction they steer as the wind changes. Unfortunately, the ability to tell exactly which direction the wind is blowing can be …
Introduction For our final project, our team built a touch screen controlled Etch-A-Sketch we call Touch-A-Sketch. The Touch-A-Sketch is the first of its kind that allows users to draw on the touchscreen and sketches the drawing on the Etch-A-Sketch by controlling the knobs on either corner of the toy. There are four main components that …
Due to continuous developments in power electronics and advanced semiconductor devices, the brushless DC motor (BLDC), also known as the electronically commuted motor, is seen in commercial and industrial applications. If you are looking for a brushless motor design, this might aid your requirements. TheĀ STEVAL-PTOOL1V1Ā from STMicroelectronics is based on theĀ STSPIN32F0B controller, which is an advanced …
Introduction The inverted pendulum is an interesting case in the study of control systems because of its unstable nature. A pendulum is considered inverted when its center of mass is placed above its pivot point, meaning that its only equilibrium point is when its center of mass is directly above the pivot point. This is …
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 …

Introduction Bot Ross is a moderately sized 2-D contour plotter, capable of drawing images with a resolution of roughly 1 mm. The design consists of a pen with degrees of freedom in the x and y directions, actuated using threaded rods controlled by two stepper motors. The pen may be raised or lowered using a …
