Arduino Pin Turns On Transistor>>Transistor Turns On Relay>>Relay Connects Appliance To 120V Power Outlet. With that out of the way, you should also use a resistor to connect your Arduino to the transistor. This prevents the transistor from drawing excessive amounts of current and burning it ...
A relay transistor driver circuit can be considered a great example of a boost converter circuit. The flyback diode connected across the relay is introduced to short circuit the reverse back EMFs from the relay coil and to protect the transistor whenever it switches OFF. If this diode is remov...
The Arduino is a fantastic development board for testing ideas and products, but unless you learn how to connect it to external circuits, it is rather pointless! In this article, we will learn how to do just that!External Devices and Circuits...
Identify the hot power wire (red wire in the diagram above) in the cord leading to the light bulb and make a cut. Connect the side leading to the light bulb to the NO terminal of the relay, and the side leading to the plug to the C terminal. This way the relay is on the hot s...
The way the relay is used, is thus: if you want the relay to turn something off when signalling it from the Arduino, you must connect your application's power source - in this case the battery for our LED - to the normally opened (NO) pin. If on the other hand you want to use ...
In this tutorial we will learn how to control a brushless motor using Arduino and ESC. For this example, I have an outrunner BLDC motor with...
How to Connect a Schmitt Trigger to the Arduino Let’s see how to use a Schmitt trigger to debounce switches with an example project that increases the count of a counter each time a button is pressed. These are the parts you will need to build this project: ...
I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.

The words “digital” and “1-wire” make this sensor really cool and allows you, with a super simple setup, to read the temperature of one or more sensors. You can even connect multiple devices together, utilizing only one pin on your Arduino. The more I play with the Arduino, the ...
