I was working on my WALL-E robot and just finished. I then installed all the electronics and the EZB and the blue light came on and a red one was blinking. A few days later, my EZB stopped working and seemed to have "blown out". I am unsure of how this happened as the chip was lit up with blinking lights before, although I never actually got to use the robot with my computer. It was working fine before for the past few days and suddenly it shorted out. More specifically, I hooked up the battery source of 6 (non rechargeable) AA's and the light came on and it appeared to work fine- then the blue light started to dim and then shut off. I then decided to hook up some fully charged rechargeable AA's to the unit. It then flickered and stopped working. I am horrified and worried that it's broken...Should I just buy another fuse? should it work again? What should I do? Please Help! Thank you...
