as many have suggested arduino you can go on amazon and buy project kits and sensor kits fairly cheap. i bought one that came with 50 different sensors lasers ir receivers ect. you can also buy a components kit you will get a breadboard jumper wire diodes resisters encoders capacitors all that stuff. you can go on banggood or other chinese purveyor of knockoff goods to get a soldering iron cheap. i use a ksger i picked it up for around 50$.
