1w power led for rides so easy a handy circuit a few resistors and two transistors is done with MOSFET with 350mA current limit because 1w LEDs used in the circuit used IRFU9024 P channel mosfet instead of similar interventions in any P channel MOSFET can be used.

433MHz RF relay control circuit pic16f628
RF relay control circuit PIC16F628 microcontroller used in the donor card 433MHz RF transceiver module with 8 buttons (433.92 MHz) command is sent to the recipient. Sadder still used in the RF receiver in the receiver module and PIC16F628 has 8 relays.
The transmitter circuit in the receiver circuit relay 12v to 5v supply necessary for working with the required 5v 12v relay spot available in petite pic and relay supply in this way is equal.
