Inconsistent result

                                              

I played with an ultrasonic motion detector that had been set up on arduino – I dropped a cigarette butt into the holes of the prototype I made - the motion detector picked up on this motion inconsistently, I changed the variable on arduino for different results, but it remained inconsistent and so Pete said we could try to find a different sensor that works better. 

He also suggested I make a different butt bin with closer and smaller cig holes this too could possibly produce a better result.

I thought this wouldn’t be such a bad idea because when I had asked a smoker why some smokers dropped their butts on the ground she said, “ it’s not that you want to, but there isn’t enough bins around” and so I thought if I designed another bin it could potentially be a prototype for a mass production to solve this problem J (I can dream right) lol
