Building simple circuits | Model Railroad Hobbyist magazine Interestingly, you do not need to understand how a circuit works to build it. If you get the parts connected the way the schematic specifies, it will work. Probably, unless a component got damaged, or the circuit was a dud in the first place. For that reason, I suggest you try all new circuits in a solderless breadboard before turning the iron on. Simple Solar Circuits : 11 Steps (with Pictures ... The circuit doesn't deliver a DC voltage to the LED but a high frequency pulse. This creates the same brightness from the LED as a constant DC voltage while needing less than 50% of the energy enabling a single 1.2 volt cell to be used. Since this circuit does not have a resistor for the LED it further increases the circuit’s efficiency.
