Two-Arduino UART Chat Kit with LED Indication – Learn Serial Communication

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine two Arduino Unos talking to each other: you type a message on one computer's Serial Monitor, and it instantly appears on the other, with LEDs flashing to signal incoming data. This kit turns that idea into a hands-on project you’ll build in under two hours, mastering the same UART communication used in embedded systems everywhere.

What You'll Build

A working serial text chat link between two Arduino Uno boards. You'll send messages from one Arduino's Serial Monitor to the other, with LEDs that blink each time data is transmitted or received, giving immediate visual feedback on the communication.

What You'll Learn

• Configure UART serial communication between two microcontrollers
• Write and upload Arduino sketches that handle sending and receiving single characters
• Connect TX/RX pins correctly and set matching baud rates on both sides
• Use LEDs to visually confirm serial activity with simple digital write commands
