It is an advanced lighting driver based on wireless transmission 433MHz implemented on a popular family of circuits from Princeton. A set of three wireless sockets with remote control – from which the remote control and RF receivers were used.
The main element of the driver is popular PIC16F84A. It controls 6 channels of lighting by analizing the states of decoder PT2272.
The remote control has 4 pairs of buttons ON/OFF, only three pairs were used because there are only three receivers in the set.
What it is for:
The driver can be used for a chandelier with six light bulbs: you can separately switch on/off each bulb using only one pair of the buttons on the remote control. Each pair of the buttons can be used to control lighting in hall, kitchen, room etc. You can lit any number of bulbs in each room. Thanks to that you can save energy, because there is always exactly as much light as you need. You can control not only a chandelier, the possible application depends on your individual needs.
How it works:
Pressing the ON button on the remote control causes switching on a bulb in the selected chandelier, another pressing ON switches on another bulb and so on, until all 6 bulbs are on. In that moment, another pressing ON causes all bulbs switch off and after some time a bulb switches on again. This is a cycle. Pressing the OFF button in any moment will switch off all bulbs, pressing both buttons simultaneously always switches on only one bulb.
