Arduino-Nexa

Overview

Use Arduino, 433Mhz transmitter,receiver and Nexa remote switch to turn on and off real lamp.

Step 1: Material

  • Arduino uno board

Step 2: Set up Arduino with 433Mhz transimitter and receiver

alt text

This link has a pretty explanation about datasheet about transmitter, and this one for receiver. After you read through the datasheets, you should be able to understand how to connect the pins to the arduino.

Step 3: Use Nexa with Lamp

Step 4: Receiver test

Run rf_receiver.ino on Arduino, you should be able to see output. Mine looks like this

sender 15556058
no group
on
recipient 13

sender 15556058
no group
off
recipient 13

Step 5: Final step! Hack

Change the data in homehackingeasy.ino according to the result we got from the above.

unsigned long sender = 2051610;
unsigned int recipient = 0;
bool command = true;
bool group = false;

Now run^^
