You can salvage some nice motors out of optical drives but they can be tricky to control ... His test circuit uses six 2N2222 transistors to protect the Arduino from excessive current.

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

The Arc Controller has been specifically designed to provide power to the Maker by adding high Amp motor control to your projects. Watch the video after the jump to learn more about the Arduino ...

UPDATE: There are some cheap motor driver boards for Arduino projects at the end of ... bottom two are common-emitter connected. If both control connections are pulled high at the same time, all four ...

3. DIY Projects: Perfect for DIY enthusiasts who want to add motor control to their Arduino projects, such as remote-controlled cars or home automation systems. 4. Educational Purposes ...

ClearCore CLCR-4-13 is an industrial IO and motion controller that can be programmed using the Arduino IDE. It handles up to four axes of step-and-direction motion control (500kHz max step rate), and ...

So I needed a way to map the RC receiver’s two sets of motor control ... on the PNP transistor. A positive signal would then go from the battery, through the transistor to the Arduino.

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...
