HI , i want to make a wireless remote controlled car without using microcontroller . how should i go about it .
You can use RF transmitter and reciever for the same. For that u vl be needing an encoder circuit at transmitting end and a decoder circuit at recieving end. Make a remote to control your robot and connect it to the encoder along with transmitter. At the car end make a simple L293D based motor driver card and attach it to the reciever along with decoder.
hi, me and my friend are trying to do a rc car with atmega8 controller and a arduino uno board we have a 433.92mhz receiver and transmitter with ht12d and ht12e encoder decoder pair... can anyone pls tell me the pins that we need to connect from the microcontroller to the encoder and decoder.. were using arduino uno as transmitter and another atmega8 board as receiver..... our encoder and decoder have no dip switches and only 4 data pins... thanx in advance for any usefull reply........
to make a car ther is no need of microcontril
you connect D0,D1,D2,D3pins of ht12d
decoder to L293d motor driver
her all pins are by default HIGH
to move forward or backward you need to press
two switches simultaniously
i tried it and its working
use the circuit in EGLABS
connect d0,d1,d2,d3 to L293Dmotor driver
instd of leds
You may also go for readymade RF modules which are readily available in Mumbai and Pune, rest I dont know. These RF modules are very easy to use and satisfactory as well.
