MODES OF OPERATION

How does the module operate?

Mode 1 Mode 2 Modes 3 Mode 4 Mode 5 Mode 6 Mode 7 Mode 8 Raspi Mode

PAIRING: The first thing we have to do is to pair the socket to our Module. The easiest way to do that is to make sure the power is disconnectd from the Module. Then temporarily connect the 3.3v pin to pin D10 with a jumper wire, which is actually Raspi Mode.

Turn the power on to the Module. Then 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 temporarily to the 3.3v pin with a jumper wire. The socket will then turn ON. Remove the wire from the D2 slot on the breadboard and the socket will power OFF. Your Module is now paired with the socket. Turn the power off and disconnect the wire from pin D10. You can then choose whichever Mode you want by connecting the jumper wires to D2, D3 and D4.

MODE SELECTION: We select the desired mode by making pins D2, D3 and D4 either HIGH or LOW. We do this by connecting the pins to the 3.3v pin using the jumper wires supplied. You can then operate the Module in 8 different modes described below. The power should be disconnected when you are connecting the jumper wires. 

IMPORTANT:Disconnect the power supply  before connecting the various pins.

You need to supply an old mobile phone/cell phone. The backlight on the screen must stay illuminated for as long as the phone is ringing. We call this the receiver phone or Rx. To turn the socket ON or OFF you make a call from any type of phone, mobile/cell phone or landline or even web phone. We call this phone the transmitter phone or Tx. You need to find out how long the back light stays on, on the receiver phone Rx, for a given number of rings from your transmitter phone Tx.

The critical thing to find out is how many rings of Tx will keep the backlight on Rx, ON for 20 seconds or more. For example, when I ring the my old phone which is attached to the Module, it takes 5 rings to keep the back light on for just over 20 seconds. Remember that the backlight will probably stay on for a while after you terminate the call. You will need to test this yourself because your phone may be different. With most phones two rings from the transmitter phone will turn the back light on for under 20 seconds and seven or eight rings will keep the backlight on for longer than 20 seconds and  under 40 seconds. 

The Module is attached to your old mobile phone by means of the LDR (light dependent resistor) and black tape. When your mobile receives a call the backlight comes on for a period of time. This is sensed by the LDR which activates the socket depending on the amount of time the backlight stays lit.

Mode 1  turns the socket ON with a long number of rings and OFF with a short numbers of rings.

Mode 2 turns the socket ON with a short number of rings and OFF with a long number of rings.

Modes 3 to 7 operate like a countdown timer. If the times mentioned don't suit your particular application please let us know and we will adjust the countdown times to match your needs.

Modes 3 turns the socket on for 1 seconds.

Mode 4 turns the socket ON for 30 seconds

Mode 5 turns the socket for 60 seconds.

Mode 6 turns the socket for 30 minutes.

Mode 7 turns the socket on for 60 minutes.

Mode 8 toggles the socket on and off.

Please follow the links for a detailed description of each mode. As you can see, Modes 3 to 7 operate like a countdown timer turning the socket OFF automatically when the time runs out. Mode 8 toggles the socket ON and OFF with each alternate phone call.
