With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips”- for instance ... chip and insert it ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

Evil Mad Scientist Labs brings us this easy to make LED blinking circuit. The idea is to put ... all attached to a small section of perforated board. Duplicating this project should be easy ...

Here is the circuit for the Sparkfun Active Low style sensor. PIR Pin “+” connects to Arduino +5 one side of ... flash the on-board LED in front of digital pin 13. This is a good way to ...

Let it hit your red LED and you’ve lost a point ... Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.

Using properties of a series circuit, the sum of the voltages across the LED and resistor R must equal the supply voltage. \({V_s} = {V_{LED}} + {V_R}\) Now substitute the supply voltage (\(6V ...
