07 Nov 08 The Robot: Phidgets USB Interface Board Kit works

The Phidget interface kit arrived and so did a few of the analog sensors that I ordered. I can’t believe just how simple they are to use and just how friendly and comprehensive their SDK is!

Here are some pictures:

Phidget Interface Kit

This is the interface kit itself. It’s a regular USB device and draws minimal power. Along the top of the board are the analog sensor inputs. Each is connected via a simple 3-pin wire, ground, data and +V.  Along the right hand side are 8 simple digital on/off inputs. Along the left hand side are 8 just as simple digital on/off outputs. In this case, I have connected the Phidgets analog light sensor which you can just about see on the left of the picture. Download the Phidgets Linux SDK from their site, compile, and run the examples. The range on the light sensor is fantastic. It advertises 0 to 500 range and does indeed live up to the promise. Pitch black and the sensor reads < 5, and pushed up close against a 400W light, the sensor reads > 480. Normal light conditions and the sensor reads between 30 and 180 – very very useful.

The SDK comes with plenty of examples and is incredibly user friendly! I would recommend these all day long.. it really is plug and play.

IR Distance Sensor

And here’s a distance sensor. It’s a simple IR mechanism that ranges from about 1m to 10cm. There are also 10cm to 5mm sensors available. Again, works great, really reliable.

So now these work, I’ve ordered some more and they’re on their way. One temperature sensor, two voltage sensors, some sonar sensors and more IR sensors – fantastic products.

In the mean time, I’ve ordered a load of clear acrylic and plan to start putting a body together shortly.

I’m still having a little trouble talking to the motor controller so if anyone has any I2C knowledge, please please let me know. I don’t want to buy a prebuilt base.. I think it’s cheating.
