$50 robot tutorial
A picture tutorial
between these 2 tutorials you should be able to modify your servo. Basically there are 2 things that need to be done. The first is modifing the servo so that it always thinks it at the zero position. The second is clipping off a piece of plastic so that it can go 360
For this little project you will need:
screwdriver
superglue
sharp knife (sharp wire cutters might work)
maybe a file, depending on how well your cutting turned out
your programming board, and a few wires to connect the servo
