We have a collection of almost 500+ Arduino projects with Code, Circuit Diagram, and detailed explanations completely free for everyone to build and learn on their own. The IR sensor has a 3-pin ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

Overview : This projecr implements a car speed detector using an Arduino microcontroller and an IR sensor. The system measures the speed of passing evhicles by detecting interruptions in the infrared ...

1. Fig. 1: Author’s prototype for Automated Washroom Light Using IR Sensors Circuit diagram of the automated washroom light is shown in Fig. 2. It is built around Arduino Uno (Borad1), BC547 ...

you can calculate the speed at which the car travelled from IR Sensor 1 to IR Sensor 2 as you already know the time of travel. All the calculations and data gathering are done by Arduino and the final ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR ... energy usage and user convenience. The circuit diagram of the automation device using a motion ...
