FEZ Spider distance and obstacle detection


Hi all, am using FEZ spider, here is the problem. I need to connect a PIR sensor with my spider using an extender module but the problem is i don’t know how to do this please help me if anyone know how to do this (if I can do this without using PIR and using some other way around please let me know )
thank you…!!


PIR won’t help sorry. PIR is Passive InfraRed and means it can detect IR (body heat) in a room. You need something like a PING))) sonar detector


can i connect it with FEZ spider… if u have any sample please give me…


It depends on the electrical interface of the sensor.
SPI, analog, serial, …


Yes, you can use PING with Spider. Check my driver on codeshare. All you need is TristatePort.

Here is another distance sensor that uses I2C which is also possible on Spider:


While the code is not for Gadgeteer, here are some code entries for the Sharp IR distance sensors.The Sharp devices come tuned for different distances.

Sparkfun catalog:

If you want to use an ultrasonic device, there’s also a range of Maxbotix sensors

Sparkfun catalog:


Ultrasonic module is done and will be online in few days :slight_smile:


Even better! :wink:


thnx all i’ll try it … will send a feed back after trying all these things…


hi gus how long will it take to release with drivers,
