This new lab is a complete introduction to analog and digital electronics, suitable for age 10 to adult. �Topics are presented in an increasing order of complexity, beginning with basic circuits using switches, a relay and a buzzer. Builders then advance to circuits using transistors, diodes and 15 integrated circuits. �This lab has serious educational value but provides hours of fun and entertainment. Students will build projects that reward with warbles, sirens, flashing lights, even circuits that make decisions. �Includes spring-coil connectors and breadboard for quick no-solder hookups. Documentation was written by best-selling author and science writer Forrest M. Mims III. �Requires 9V and 6 "AA" batteries, not included. Price include UK carriage.
