1 4-channel remote switch controlled by any infrared remote control • works with almost any IR remote • Enables and disables 4 devices • operated manually or via infrared remote • very easy and intuitive teach-in procedure for 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. learning the pilot codes control unit Specifications • 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. 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.
