Fiddling with knobs (Using Arduino and Processing to make pong)

Recently in our workshops at university we’ve started playing around with Arduino’s and all the different kinds of sensors you can plug into them. This is something I’ve been looking forward too for a while! I always love tinkering with things so combining electrical components and processing code is great fun for me. In today’s workshop Rob introduced us to potentiometers. With these you can input an analogue control into anything, twisting the knob outputs a number between 0 and 1023. After connecting the potentiometers to the breadboard and hooking them up to the Arduino I turned to progressing to try and get them to control something on the screen. Starting off with a dot I could move around onto the screen I thought I could then move onto a ‘visual representation’ of pong. After...
