Here the circuit of this project uses RF module to control DC motors through a motor driver. The parallel signals generated at transmission end are first encoded (into serial format) by HT12E & then transferred through RF transmitter (434 MHz) at a baud rate of around 1-10 kbps. The same signals are acquired by RF receiver after which it is decoded by HT12D& sent to motor driver L293D. With a antenna to the TX & "no antenna" for RX it can cover a range of 60mts & with antenna for both TX & RX a range of 100mts+ can be achieved.
The main components used are:
434Mhz Transmitter & Receiver module.
LM7805 voltage regulator.
HT12D, HT12E for wireless control.
L293D for driving motors.
500rpm Motors.
9volt battery for the circuit operation.
7.2volt 36000mh battery for powering the motors.
