Selection device
Staff at the Child Development Centre asked us to make a device to develop co-ordination with reward for the children.
A motor driven rotating arm, in the shape of an arrow, is mounted on a box and covered with a transparent cover. The stop position being controlled by a press switch. If stopped within the two marked positions a buzzer and light will operate. More stopping positions can be added if required.
The children respond well to this eye hand co-ordination task and appreciate the reward.
