WebUnfortunately, the AND gate was needed for the XOR as well so two hacks were needed to get back on track with the entire PCB. The emitter of the low-side NPN was grounded and the LED + current limiting resistor moved between +5V and the collector. The single NPN circuit is an inherent logic inverter so we're slowly heading toward the logic gates. WebThese electrons can then cross the base-collector junction and a current flows between the emitter and the collector. As you increase the base voltage further more electrons flow into the base from the emitter, so … kids christmas table decor
