Control DC Motor with PIC16F877A Wirelessly

[lokster]

Hey guys, i have a project to do where our engineering teacher gave us the problem of making a mobot for a flood and wireless

i thought of making a little boat with a depth sensor using ultrasonic transducers

i want to have a remote control where i can control the servo for direction and a dc motor for speed

how is this possible? what do i add to my circuit to send and receive transmission from a remote control. e.g servo left and right to control direction and on/off to control the speed.

Any help will be appreciated

You can have a look at the TWS-434A transmitter and RWS-434 receiver all controlled by the PIC.
You can also use the Holtek HT-12E 4-Bit Encoder IC and Holtek HT-12D 4-Bit Decoder IC to send and receive and just have the uC oversee it.

Have a look at this site:

If the boat design will require an onboard microcontroller, then using 802.15.4, ZigBee, MiWi or similar transceivers might be the most straight forward method.

As not-a-moderator mentioned you can use a simple ASK type TX/RX with proper encoding/decoding, however the depth sensor, servo and DC motor control would require additional sensors and microcontroller to implement a method of control.
