RB-20 CLASSPACK of 12 Robot Car Kits at $10.00 each. Save $5.00 each, total saving $60.00

This Robotic Car is a great introduction to soldering as well as the basics of sound control and mechanical motion. The car has a electret mic that feeds noise to the control circuitry. When a loud enough sound (like a clap) is heard it will cause the car to stop moving forward and reverse itself turning slightly left for a few seconds. Then the car will resume forward motion in a different direction. You can adjust the circuit sensitivity so that very soft or very loud noises will reverse the motion.

Specifications:

• Power: 2 AAA batteries (not included).
• Includes sound activated circuit.
• Circuit board requires solder assembly.
• Unassembled printed circuit board Soldering required.
• Learn motor theory, transistor switching and R/C time constant circuits.
• Changes direction with a loud sound such as a whistle, a clap or when it hits an object, it will then automatically reverse itself for a preset time and then resume its new course.
