'lo all,
I'm embarking on my first Arduino project; a number of light sources controlled by a number of rangefinders. I've built a relay switching part to control the lights, but the rangefinding part is causing me trouble.
I don't really want to shell out for a bunch of the Ping sensors, 'cos they're quite pricey, and it seems to me that you should be able to the difficult bit in software. Plus, I found a bunch of transducers on ebay for cheaps, and I reckon I'll learn more doing it this way: I've got a knowledge of the basics in electronics, but semiconductors and loads of resistors and stuff start to confuse me
Looking around the internet, I found this diagram for building such a thing with a different breed of PIC:
My questions then: could I build something like this with my Arduino instead of whatever PIC they've used? What, if anything, will I need to alter? Will I need to add any amplification to the receiver? If so, can I do that with transistors?
Any help gratefully recieved
