Elenco's PK-201 Experiment #25: Battery Immunizer

 
This is an experiment to show how to design a circuit immune to a voltage drop (weak battery). In the video, when one LED is lit, the circuit is connected to a modified 4.7 volt supply. When both LED's are lit, the circuit is connected to the 9 volt supply. The LED that lit both times is representing a circuit immune to voltage drops.
