I am working on a circuit that drives some 7-seg displays and a relay based on a sensor reading. I have the circuit built and I am powering it with an old variable supply I built in a class. The supply is at 5V when its not loaded and when I connect it, it drops down to about 2V. So I adjusted it up to 5V. My relay clicked on but nothing works on my 7-seg displays. Now I realized that I somehow shorted the msp430s VCC and GND pins together and the same thing for the launchpad which gets really hot when its connect to the usb now. I cant figure out what I did that caused this and I am looking for some help. Ive attached a basic schematic of my circuit plus the relay driver that I am using. Thanks!
