Help me make a wireless RF remote
I want to control upto 8 dc toy motors wirelessly(clockwise and anticlockwise rotation).
I want to make my own transmitter and receiver circuits.
Can any one please help me for making this wireless remote control.
And you would be helpful if you provide me a working schematic diagram.
The TWS-434 and RWS-434 are extremely small, and are excellent for applications requiring short-range RF remote controls.
If you see inside china made remote control car. They use two small ICs- TX 2B and RX 2B. They are 5 channel 27MHz(read the packet if it is 27MHz) radio remote control transmitter and receiver. You will find necessary parts in the car and its remote control. Datasheet is available on net.
You can see here : 5 channel radio remote control circuit based of TX-2B / RX- 2B pair
See the above link for connection
Is number of channel denotes the number of switches?
And i need to make a dual frequency remote?
How can i do that?
by using two transmitters in the same housing and coupling them together to fire out both frquencies at the same time
like was said the tx ic is small enough to lose quite easily so losing two of them shouldn`t be a major issue
