I'm building a remote controlled robot. I'm stuck in building the remote.
I referred from think labs(**broken link removed**.)
i'm using r/f module(Tx & Rx) of 433MHz, HT12E/HT12D decoder and encoder
and L293D motor driver(to drive 12v motor around 500 RPM).
I constructed transmitter and receiver on bread board.
I'm attaching both the images of Tx & Rx.
I've tested motor driver IC by giving logical inputs and 25 to 30 v
i/p voltage, it's working.
What type of antenna should i use? They said to use any single stand wire
of 15-20 cm.
Please help me
