Step 1: Material Preparation
In this tutorial, the items needed to conduct this project are:
- 2 Arduino UNO
- 2 LORA SX1278 Wireless Transceiver
- Red LED
- Blue LED
- 220 Ohm resistors
- Touch button
- Jumper wires
Step 2: Hardware Installation
Step 3: Source Code
- Download the test code and open it by using Arduino software or IDE.
- Make sure that you have choose the right board and the corresponding port (In this tutorial, Arduino UNO is used).
- Then, upload the test code into your Arduino UNO.
- Transmitter file upload to one of the Arduino UNO and receiver file upload to another Arduino UNO.
