hello to all..i am a newbie here but in the following line i will explain my project idea any help about it will be greatly appreciated..ok i want build a r/c car control by optical control ..i want a very simple control for my first project ..i want be able to control just the forward and reverse only at this time..is there any idea about shematics with parts i should use ..also i specify i want to do it with low cost parts.. i forgot to mention i want build both transmiter and receiver for the car.


Thanks in advance

Sounds like a fun project. Radio control can be expensive ($30US) for a novice.

I suggest starting with a standard IR remote transmitter and learning about the signals that it sends. Plenty of articles here that describe how to learn this.
 
thanks for the reply

thanks for your reply ..ok since i am new here i like if someone can point me to the right place on the board to find how to build a simple ir transmitter and also receiver for my r/c car ...the car will itself will have low power (3v motor)


thanks again

thanks Nigel ..i checked this on your website but seem very complicated to me i am just a newbie..i was looking for somethings like shematics with parts description (just a simple things to build) because i just started..thanks for your help

Radio control used to cost hundreds of dollars, $30 is INexpensive.

Well the diagrams are simple enough, but you need to program the PIC's. You might try checking the Holtek range of remote control chips?.
 
Just a few suggestions:
You might want to look at the H-bridge circuits for your car's forward and reverse actions. Try this site for it:

When using say Infra Red, think of using a lense to amplify your signal.
A PIC could make life easier, but for your project I think it would be more fun to go without.
Take a look at the HS0038B, it's a IR receiver that may help alot.

Good luck.
