Ultrasonic sensor

Need to get the ultrasonic sensor up. Anyone want to have a go at it?

Code: http://www.raspberrypi-spy.co.uk/archive/python/ultrasonic_1.py

Basically, the code goes as follows:

• Imports for Sensors/GPIO
• Setting up GPIO ports as Trigger (out) and Echo (In) which basically is the sensor sending out a signal, it bouncing back and then depending on how long the signal was active until it was picked up again, measure the distance
• Calculating distance by triggering ultrasonic sensor and picking it up again with echo. The sensor is seto false and time has been imported.

I will create some simple code as soon as possible

Nice one! I wrote some code for a speed gun here: https://github.com/STJRush/rpi/blob/master/ultra.py
