Hey Guys - I've got a basic project which lights 32 LEDs which are set up in series of 4 all in parallel as shown below. As each LED is 3V / 20ma, I didn't add in resistors or anything to each series. Unfortunately, I've twice now run into an issue (thermal runaway?) where the LEDs are only runni…

Phew...
Thank goodness I didn't build it to test
