I have tried to make a rf remote for my robo base plate.
four keys viz: forward, backward, left and right, produce 4-bit binary codes when pressed.
these codes are applied to the control lines of L293 motor driver IC.
D3 D2 D1 D0
F 0 1 1 0
B 1 0 0 1
L 1 0 1 0
R 0 1 0 1
I want to transmit these codes to the driver IC wirelessly using a RF module.
The problem is that the module i have got transmits data on a single pin and the encoder decodr pair i have used donot produce accurate conversion of the codes onto a single line(pin)
I need help in converting the codes faithfully into a voltage
and transmiting it over the module and then converting the voltage level recieved into a 4-it code accurately.
urgently require suggestions.
