This kit uses a single AA battery holder into which the user places a battery. LEDs then illuminate to show the remaining capacity of the battery. The circuit uses a quad operational amplifier to provide a reference voltage and comparators to determine which LEDs should go on. This makes it a great kit for studying operational amplifiers.
Testing of the kit can be performed using an adjustable power supply, or withacircuit tester (consisting of an AA battery holder, variable resistor & crocodile clips).
