IR RF Transceiver Circuits 8 Channel Remote Control

IR and RF transceiver circuits PIC16F628 microcontroller based on the software assembly prepared by the donor of the above değşiklik without just sittin ‘with IR or RF controls can be made 8-channel and 4-channel different circuits there buyers card relay controlled RF modules price is high, the IR transceiver be used for long-distance or the RF circuit module is used. Asm source code control system could also solve the enlightened can help.

The circuit, which includes the PIC16f628 microcontroller, is very flexible. You can decide which receiver outputs are latched and which are momentary. The Manchester coded transmitter output is great for the cheapest ASK radio modules or infrared control. The units can be configured to a unique address that must be matched to control the devices.

The only difference between the 4 channel and 8 channel versions is the software inside. The 8 channel transmitter has one button (S1-S8) per channel. The 4 channel transmitter uses buttons S1-S4 to turn on and buttons S5-S8 to turn off channels 1-4 (use with the latched outputs on the receiver). Diodes D1-D4 and jumpers J1-J4 are optional and are used to set the transmitter address.

The higher supply voltage provides higher transmit power, but the V+ range for the PIC MCU is 2-5.5VDC. When V+ is higher than 5VDC, use separate power for the mcu.

Diodes D1-D4 and jumpers J1-J4 are optional and are used to set the transmitter address. The V+ supply voltage should be between 2.5-5.5VDC. It is practical to use two or three AAA batteries.

Select the V+ supply voltage between +6-15VDC according to the relay voltage values. Use +6VDC for 6V relays and +12VDC for 12V relays.
