How to make RF Controlled Robot.

with 1 Comment

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:-

1.RF module

2.HT12e (encoder ic)HT12E HT12D Encoder Decoder Pair

3.HT12d(decoder ic)

4.L293d (motor driver)2 piece l293d ic

5.7805 voltage regulator


7.resistors 33k and 730k

8.push switches

 9v battery

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.
