Bergilfan 0 Posted May 1, 2019 Share Posted May 1, 2019 I have made a little music box using two piezoelectric buzzers (each one connected to P1.2 and P1.3). I also have a blue led connected to P1.1. if I wore my breadboard directly from the programmer board it works fine! But when I place the msp430 IC on the breadboard it doesn't seem to power on. I use 4 AA batteries connected to a DC regulator that outputs 3.3V to VCC. The regulator works fine. I've even tried the 5V and still nothing. I took everything off except the led and the led would not turn on via the mc. Has anyone else have any issues with this? I am new to all this so it's probably something I did wrong.
