RASPI CONTROL

Control up to EIGHT remote control sockets from your Raspberry Pi or microcontroller.

This extra feature was added as an afterthought to our Module because we thought it would be useful. The eight sockets are controlled by the Raspberry Pi or microcontroller and not with the phone backlight.                                                              

The picture and diagram below are hopefully self explanatory.

Raspberry Pi Connections

To enable our Module to operate in this mode it is necessary to make pin D10 HIGH by connecting the 3.3v pin to it with the jumper wire. It's also necessary to have a common ground between the Raspberry Pi or microcontroller and our Module. These connections must be made with the power to our Module being disconnected. See diagram.

So when a GPIO pin on your Raspiberry Pi or output pin on your microcontroller goes HIGH (between 3v and a max. of 5v) our Module transmits a radio signal at 433MHz to turn a socket ON. When the signal from the Raspberry Pi or microcontroler goes LOW, our Module transmits another signal turning the socket OFF. The socket only remains ON for as long as the GPIO pin or microcontroller pin remains HIGH.

PAIRING OF SOCKETS TO OUR MODULE

Do this BEFORE you connect your Raspberry Pi or microcontroller.

Suppose you want to pair a socket to pin D2. You simply press the pairing button on the socket of your choice. Usually this will result in a flashing light on the socket.

You release the pairing button and then make pin D2 HIGH by connecting it with a jumper wire to the 3.3v pin temporarily. The socket will turn ON. When you disconnect the jumper wire from the D2 slot in the breadboard the socket should turn OFF.

Now every time pin D2 is set HIGH or LOW by the Raspi or microcontroller that particular socket turns ON or OFF.

You can then repeat this procedure for pins D3, D4, D5, D6, D7, D8 and D9 if you like.

WHY A BREADBOARD INSTEAD OF A PCB?

By using a breadboard we are able to give useful employment to a person with Special Needs who wouldn't be able to solder. The breadboard is highly reliable and safe as it only has 5v DC connected to it.
