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 ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

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 ...

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...
