he video above explains the basic theory that relates to data transmission, namely how electromagnetic waves are generated by antennas and how they encode 1's and 0's. Non essential information for a hobbyist, but really interesting none the less.

Component list:

•1 X Arduino Uno

•1 X 433MHz RF link pair

•3 X LED

•1 X Piezo Buzzer

•1 X Push Button

•1 X Resistor 330Ω

•50cm Single Core Wire

Equipment needed:

Soldering Iron


Observe the schematic and the completed circuit (video tutorial also available)

Make sure you do ALL of the following:

1. Connect the module in the following manner Vcc pin connects to Arduino 5V GND to Arduino GND and DATA to Arduino Pin 12

2.The button connects to Arduino pin 2 and needs to be earthed

3. The antenna needs to be soldered onto the module. The antenna is 35cm long and soldered into an antenna slot in the transmitter module.

4. The antenna is to be straight if possible.
