RX TX pair of small RC car Project

Hello Guys,

Had been away for a while..

Missed you all.

So this time I am working on a project of a RC car

Small on easy one yet i am stuck in the RC part of it...

I want it simple,

I know I can achieve this with Arduino XBees and all but this time I wanna keep this simple..

I want a TX RX pair with which i can just run the motor with the help of a switch..

thats it...

Just a button connected to TX and a motor connected to the RX along with the battery

It all started here... http://letsmakerobots.com/node/26267 Once again, I set out on a quest to build yet another controller. I don't know what to call it really, … Read more

Serial Pins on AXE020

 

On the tutorial Picaxe for dummies Fritsl says the following:

serial uart with only rx or tx not both

Can I deliver serial data from one direction to enother (2 mcu) only with tx :

MCU1                                       MCU2

      TX<-------------------------------------<RX

 

?

Arduino + a doorbell's wireless modules

hello, hope you had a merry christmas, and will have a happy new year!

I found a wireless doorbell, and i would like to know it it would be possible to attach the button of the doorbell, to the TX pin on the arduino, and the receiver to the RX pin, sorta like this:

I think i would then be able to serial print what ever i want, and serial read it with the other arduino. say controll severall motors, even if it just has one button, would this be possible?
