IR remote control

(1/1)

Hi guys,
I need to remote control one servo motor. I have some old remote controls lying around, which I want to control the servo with (both clockwise and anti-clokwise) . Do you have any ideas about how I can make/ where I can buy a cheap IR receiver that is easy to connect to a servo motor??

hgordon:
The IR remote modulates a bit pattern on a 36kHz or 38kHz carrier, so you need an IR detector that can receive and demodulate the incoming signal - here's an example -

We use a Vishay TSOP1738, which is functionally equivalent to the Sharp part.

After that, you'll need a processor or logic that can capture the bit pattern from the detector and convert that into servo commands.  Here's an example of a similar project.
