Boe-Bot IR Frequency Dectection

obnauticus

Does anyone here have a program for the boe-bot to dectect or "lookup" any frequency on IR·and store it into a variable for later use, or any feasible· method way of dectecting·an IR frequency and storing it into a variable?


Thanks in advance [noparse]:)[/noparse]

Look at the description of the COUNT statement in the Basic Stamp Manual. This can count the number of pulses that occur in a specified time frame. You'd need an IR phototransistor to provide the pulses.

Why do you need this? Most IR remotes deal with from 38 Khz to 42 Khz, but are not particularly picky about it.

Meaning, even a 38Khz IR Detector will react to 42 Khz signals, usually.

We are trying to take advantage of other bots that are using IR for navigation (i.e. send them the frequency that they are sending out). An other idea is to just generate power over the spectrum that creates so much noise that they cannot see their IR anymore.

First of all, that sounds like a 'rude' thing to do. Second of all, 'jamming' another robot's IR is not hard at all, if they're using an off-the-shelf IR-Detector -- just use FREQOUT IRLED 38500 -- oh, except outputting that constantly can't be done with a BS2, if you want to do anything else like drive your robot.

It's interesting that the first or second thing some people think of when they get a robot is "Now, what can we crash into?"
