Data rate 200bps to 3Kbps depending on the supply. Operating voltage: 5 Volts PIN DESCRIPTION Voltage Regulator 7805 Led Electrolytic Capacitor L293DE Motor Driver IC HT12D Decoder IC HT12E Encoder IC 434 Mhz Transmitter Receiver Kit Transmitter PCB Layout Receiver PCB layout HOW TO MAKE REMOTE Cut the Parts as given in picture above:   Remote will be shown like this   Connection made as given in picture above for DPDT Switch   CIRCUIT CONNECTION Switch Connection Transmitter (Remote Controller) connection Connect Pin 1 to 9 and pin 14 to the ground of HT12E IC Connect pin 16 and 15 via 1M resistor of HT12E IC Connect Pin 17 of HT12E to data pin of RF link transmitter and pin 18 to the 5v ( Positive rail on breadboard ) Connect pins 10,11,12,13 to the DPDT Rocker switch (s2 and s3 as shown in the photo. Connect Pin 1 of RF link transmitter to GROUND and pin 3 (VCC) to 5v and connect antenna to pin 4. Connect the ground pin of 7805 voltage regulator to the ground ,Vin to switch s1 one point and other point to 9v battery then c1(100uf)’s positive Vin and negative to ground and then Vo to Positive rail and c2 capacitor. Positive to Vo and negative to gnd. 1k resistor one terminal to ground and other terminal to negative of led and positive of led to the positive rail. Receiver (RC car) Connection Place the decoder IC(HT12D) the motor driver IC and the RF link receiver to the breadboard Connect the 1 to 9 pins of decoder IC to the ground Pin ten of ht12d goes to pin 2 of L293d, pin 11 goes to pin 7, pin 12 goes to pin 10 and pin 13 goes to pin 15. Pin 14 of ht12d goes to pin 2(data) of RF link receiver. Pin 15 is connected to pin 16 of HT12D via 50k resistor. Pin 17 is connected to 1k resistor one terminal and other terminal of resistor to the -ve of led and the positive of led to the 5v rail of breadboard. Pin 18 is also goes to 5v rail. Pin no. 1,8,9,16 of L293D goes to the 5v rail. Pin no. 4,5,12,13 to the ground. Pin 3 and 6 connected to motor m1 and pin no. 11 and 14 to the motor m2. All three ground pins in the RF link receiver goes to GND rail,vcc1 and vc2 to 5v rail and antenna is connected to Pin 8(ant). Now connect one 1N4001 Diode to breadboard connect Positive of diode to the one point of SPST Rocker Switch and other point of Switch to the 12v li ion battery positive point. Negative point of diode to the positive rail. If you want to make this RC car on PCB:
