Learn how to interface the GP2Y0D810Z0F infrared distance sensor with Arduino Uno and a 16×2 I2C LCD to detect objects within 10 cm, with circuit diagram, code explanation, working principle, and real-world applications.

An Arduino Uno is used in this do-it-yourself RFID attendance system to track students and employees automatically. comprehensive project tutorial that includes LCD interface, circuit connections, programming code, and helpful implementation advice for beginners.

This tutorial is focused on bringing out all the different types of Arduino development boards and doing a quick comparison of their features and applications so that you will be able to make a better choice when you want something more than the popular UNO and nano boards.

In this project, we will make a sun tracking system which will help the solar panels to generate maximum power.

Often we see visitor counters at stadium, mall, offices, class rooms etc. How they count the people and turn ON or OFF the light when nobody is inside? Today we are here with automatic room light controller project with bidirectional visitor counter by using Arduino Uno. It is very interesting project for hobbyists and students for fun as well as learning.
