n this tutorial, we will Control a 16x2 LCD Display using Raspberry Pi. We will connect the LCD to GPIO (General Purpose Input Output) pins of PI to display characters on it. We will write a program in PYTHON to send the appropriate commands to the LCD through GPIO and display the needed characters on its screen.

Learn about different types of transformers, including step-up, step-down, isolation, and autotransformers. Explore their working principles and practical applications in power systems, electronics, and industrial use.

Build an automatic toll gate system project using Arduino with RFID, IR sensors & servo motor. Complete circuit diagram, code & step-by-step tutorial for beginners.

In this arduino based project we are going to interface a 5 RGB (Red Green Blue) LEDs with Arduino Uno. These LEDs are connected in parallel for reducing PIN usage of Uno. Check out the complete tutorial here.

Learn how to create a basic gas leakage detection system with Arduino and MQ-5 sensor. A useful DIY project for monitoring flammable gases like LPG and methane. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

This tutorial shows some of the basic capabilities of an Arduino and it’s integration with Ubidots. After doing it, you'll learn what an Arduino is, what it does and how you can set it up to turn an LED (or any other actuator) on and off from your Ubidots account. All you need to get started is an Arduino board and the official Arduino WiFi Shield.
