 26 Dec 2008 14:39 simple radio control |
|
|
|
|
I want to control a device by radio, three states: equivalent to left (01), right (10) and do nothing (00). Range about 3 metres in air but through a 10mm solid, so can't use IR.
Security is not an issue, but interference is - I don't want it activated by spurious transmissions. There are plenty of complex solutions involving ZigBee or KeeLoq, and plenty of solutions for radio control cars but with the possibility of interference. I need something in between.
Any ideas?

Hai Big_nige
Refer similar 2 projects from www.united77.com whose description is given below.
1.Multipurpose Four channel Radio Frequency Remote with 89C2051 microcontroller.
This is a remote controller which can be widely used in robotic application when in momentary mode. All the 4 channels can be individually programmed as latched outputs for lighting loads or momentary outputs for bell or any other automation requirement. Receiver side is equipped with four relays at the out put which can be wired in any configuration for the required operation. 4 individual addresses can be selected to operate more than one remote kit at a time.
2. Radio frequency based 4 channel Remote for robotics based on “Holtek” En/decoders. This is a remote controller which is widely used in robotic application where in momentary mode, 4 channels are available. Receiver side is equipped with four relays at the out put which can be wired in any configuration for the required operation. Individual addresses can be selected to operate more than one remote kit at a time.
Ready to assemble kits are available with PCB, Programmed Microcontrolers, schematics and component layouts on CD. Just requires to be assembled to make it work. Good luck

Hi,
You make with ZigBee of course.
Go to ST Microelectronics, and download ZigBee® REva kit library package: http://www.st.com/stonline/products/support/micro/files/um0389.zip
This is primary for the REVA ZigBee kit, containing libraries and sample applications for ST Micro's like ST7, STR7, STM32, and You can modify it according to Your needs.
And soon ST will provide a simple, USB dongle like ZigBee eval kit as well...
Robert
