After some time off for exam preparation, I back to focusing on the hedgehog feeder. 

This project is unfamiliar territory for me, so it takes me a while to get back into the swing of things. 

Currently trying to code my project to weigh the hedgehog and if the weight falls in a specific range, this will turn the stepping motor. Sounds simple but the load cell is not 100% accurate and changes weight slightly even when a constant weight is applied, let alone when a hedgehog is shuffling about on it. 

Need to do a bit more digging in similar codes...
