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 ...

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will ...

connecting Transistor Emitter to Relay and Base to Arduino Pin 2 and Collector to 5V in Arduino . connecting Push Button to Pin 8 in Arduino and Terminal 1a to GNR and Terminal 2a to 5V in Arduino .

Arduinoでトランジスタを活用する方法はいくつかありますが、主にトランジスタはスイッチやアンプとして使われます。ここでは、スイッチとしての使用例に焦点を当てて説明します。これは、Arduinoのデジタル出力の電流が不足している場合に、より大きな ...

A transistor curve tracer will tell you a transistor's electrical parameters if you know which pin to connect to which test lead. Usually you can figure this out from reading its type number and ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Suppose you are sitting in a room and feeling cold and you want your heater to be automatically turned on, and then off after some time when room temperature is increased, then this project help you ...
