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 ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

The objective of this experiment is to use a PIR motion sensor to control a fan as a on/off switch. The PIR sensor will be used to detect if there is someone in front of the fan where then the raw ...

Resistor(s) (to keep from frying the LED, 220 Ohm should work for basic LEDs) Jumper wires Breadboard Arduino USB cord (to upload code) *alternatively, you can use a strand of pre-made LED string ...
