guys,
I need your help...actually i have build a robotic arm using 2 stepper motors and it is programmed using at89s52 microcontroller...uptil now the arm is working properly..but now i want to control this micrcontroller using rf module which in turn will control the stepper motors...so which ic and what type of rf module should i use and also please suggest me a little bit algorithm that could be useful for me to program th mc....THANK YOU

you can try zigbee or microchip rf modules

Zigbee is costly. You can use simple 433 ask tx and rx with Encoder and Decoder

agree with Nandhu.. use this RF module with HT12D and HT12E pair of decoder/encoder ICs.
