Description

This is an electrical part such as a motor, light, LED or switch.

From the manufacturer:

This delightful kit constructs a model snail which follows its way leisurely along a black line drawn on a white paper surface, all the while waving its eyes adorably back and forth. When the snail finds a black line, its LED lights up green. It uses an infra-red LED and phototransistor to control the twin motors. The performance of the model can be adjusted using the speed switch (low or high) and sensor adjustment dial. Sensor, circuit board and motors come pre-wired. The kit requires screw attachment and some simple wiring to complete.

How it Works

When the sensor is positioned over a black line, the right motor moves into action, propelling the snail forwards and to the left. Once the sensor moves off of the line, the right motor stops and the left motor starts up, moving the snail forwards and to the right. When it finds the line again the process repeats, with the snail moving its way forwards in this manner.

*Please note that the line should be at least 3mm wide, and any turns of greater than 8cm radius.

Requires 2 R6/AA/UM3 batteries (sold separately)
