A simple remote controlled switch, that works

with any infrared remote control. It has four

relay outputs. Its advantage is possibility of

being controlled with any remote control unit.

Teach-in procedure is simple reduced to a few

steps.

Functional description

The schematic of the remote controlled switch

is shown in Figure 1. The device should be

powered from any 12V external power supply

with power capacity corresponding to attached

load. Input voltage is applied to voltage

stabilizer 7805 (U1). The IR receiver is a

TSOP4836 integrated circuit. The switch

functionality is implemented by the ATmega

microcontroller. The main task of the

microcontroller is to receive the signal from the

IR receiver and to analyze the codes sent from

the IR transmitter. The output is buffered by

ULN2003A, which is powering output relays.

AVT 1815

4-channel remote switch controlled by any

infrared remote control

Specifications

• Enables and disables 4 devices

• operated manually or via infrared remote

control unit

• works with almost any IR remote

• very easy and intuitive teach-in procedure for

learning the pilot codes

• power supply: 9-14V DC

When switching on high power loads, attention

should be paid to the load of the PCB tracks. To

improve their load capacity, copper wire could

be soldered. The switch has buttons for direct

switching on and off of relays without the need

for a remote control. Briefly pressing the button

allows you to change the state of the relay.

LED1...LED4 are indicating which relay is

currently on. LED 5 informs of the operation of

the device, receiving the command from the

remote control and entering the programming

mode.
