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 ...

For that reason, [Hulk] designed a simple relay module in order to cut the amount of time he spends implementing this solution in his various other projects.

From the circuit diagram of the module, it is clear that, apart from the module only a few external components are needed to build a relay-driver circuit. Yes, there is a chance to realize one simple ...

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

Introduction:In Arduino environment, it's convenient to access BT SPP like a serial port and react to the command string sent from the BT serial port. Many Arduino projects have utilized this way ...
