His test circuit uses six 2N2222 transistors to protect the Arduino from excessive current. ... Posted in Arduino Hacks Tagged brushless, electronic speed control, esc, motor.

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 ...

Because of the third transistor’s amplifying action, very little current need be drawn from the arduino pin, or high-current bridge transistors can be driven. The four diodes are included, as they ...

The High Power H-Bridge Motor Shield for Arduino is equipped with built-in current sensing utilizing the ACS712, and is capable of driving any DC motor up to 15Amp. Watch the video below to learn ...

The Arduino Motor Shield project is currently over on the Kickstarter crowd funding website looking to raise $41,500 in pledges to make the jump from concept to production. Its creators explain a ...

I have a good background working with high voltage, which for me means over 10,000 volts, but I have many gaps when it comes to the lower voltage realm in which RC control boards and H-bridges live… ...

Here, pin D12 of Arduino is used to drive a standard 5mm LED, and D13 is used to drive an Electro-Magnetic Relay through a transistor-based relay driver. Everytime the tag values match, D13 goes high ...

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...
