Therething/parts list
These are the parts we used for the protoype. For the next version there will be the option of using an PCB with the Ardiuno integrated into the design.
The ultrasound sensors are URM37's, which have a built in processor that handles the timing of the ultrasound reflections. This allows our code to be much simpler as we simply ask the sensor for the distance in CM.
The crimp connectors are optional as you can just solder all the cables on. This will make the assembly a little more fiddly, but will save a few quid (especially if you don't already have a crimping tool).
The LCD display can be any 20x4 display that uses the HD44780 protocol.
