wireless controlled robot without a microcontroller.
we can just control a lot of things using the rf module.the best part about the radio frequency is that it has a quite decent range and even it can work beyond the physical obstructions.
so we are making a simple robot to demonstrate how to use radio frequencies to switch anything
the following components we need to build the robot:-
2.HT12e (encoder ic)
4.L293d (motor driver)
5.7805 voltage regulator
7.resistors 33k and 730k
Circuit Diagrams and Explanation:-

for the transmitter side or we can call it remote
note-you can also use a LED on pin 14 to ensure the transmission is enabled.
for the robot circuit on the VC pin in l2934, we can use the desired voltage.
