This DC Motor Multiplexer allows you to control up to four DC motors in forward and reverse using one MOSFET and only 5 digital pins. For this intractable you will require: – DC motors (I used salvaged DC fans) – MOSFET (I used …
This Instructable will show you how to use a WaveShare motor/servo board with a micro:bit to power multiple servo motors. This board will make it possible to run more powerful servo motors than the micro servo motor that you can run directly from the micro:bit. Technical information for the WaveShare board is here: https://www.waveshare.com/wiki/Motor_Driver_for_mi… There is …

So I have yet again over-engineered a task, this time, a freeze-dried coffee dispenser. Why you ask, well the obvious first, it’s super fun and second, it’s the best way to learn new skills. I’m a real noob when it comes to the inner workings of microcontrollers but I really want to know how I …
Warning The Rancilio Silvia machine runs on high voltage. Any modification to it might be fatal to you or your machine, you act at your own risk and responsible for your modification. Any modification to the machine might void the manufacturer warranty. Make sure to disconnect the machine from the power line before working on …
One way to extend the functionality of the micro:bit is to use a board called moto:bit by SparkFun Electronics (approximately $15-20). It looks complicated and has many features, but it isn’t hard to run servo motors from it. Moto:bit allows you to run more powerful motors than the tiny micro-motor that you can run from the micro:bit …

DC motors are the most widely used motors. These motors can be found almost everywhere from small projects to advanced robotics. We previously interfaced DC Motor with many other microcontrollers like Arduino, Raspberry pi and used it in many robotic projects. Today we learn to control DC motor with AVR Microcontroller Atmega16. But before going ahead let’s know more about …

Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc. …

Stepper Motors are DC brushless motors which can rotate from 0 to 360 in steps. Stepper motor uses electronic signals to rotate the motor in steps and each signal rotates the shaft in fixed increment (one step). The rotation angel is controlled by applying certain sequence of signals. Unlike Servo Motor, stepper motors can be driven by …

Abstract The automated drink mixer takes orders from a push-button menu, and moves a regular 16-ounce glass under a series of inverted bottles while dispensing specified amounts of mixers to make perfect non-alcoholic beverages. Introduction If you’ve ever been to a crowded bar or restaurant and waited a long time just to get served an ill-prepared …
