If you want to develop it by yourself and it is a school project where you are supposed to prove you have the skills, why would you need our help?

Am very sorry if my request offended someone :relaxed:, but wat i meant is i want help in using atmega32u4 on pcb/breadboard and boot loading it please help me
am developing a glove using accelometer in it to control mouse pointer the gloves is uncomfortable with leanardo development board thats why i want to build pcb .
