Just finished touching up all of the joints, re-flowed everything to be sure, but the LEDs still just stay lit, with no flashing. I’m wondering if some of my components are damaged, but I’m not sure how to check a transistor using a multi-meter.
Edit: I looked up transistors (I’ve never worked with them before!) and get the measurements of 0.09v between the Base and Emitter and 0.55v between the Base and Collector on T1, and 0.01v & 0.77v on T2. My interpretation of a bipolar junction transistor suggests that they’re both working correctly, so I’m a bit stumped as to the problem!
