Radio Shack Electronics Learning Lab  (Black)

Build your own electronic circuits with the Electronics Learning Lab. It has over 200 projects that teach you about transistors, diodes, capacitors, oscillators, electronics circuits and schematic symbols. Plus, it has light-emitting diodes, an LED display and an analog panel meter that gives more visual options when building projects. Easy circuit connectors allow you to test project connections Light-emitting diodes and LED display Switches, push buttons and volume control add more options to projects Analog panel meter show project levels 69 contact springs for easy connections Battery compartment for AA cells and 9-volt battery (batteries not included) Sets of ICs, resistors, capacitors, diodes and transistors Speaker and piezoelectric buzzer element and a relay and transforme
