A programmable apparatus for selectively reading machine readable codes, such as bar codes in a user defined sequence. Each code represents an action to be performed by the apparatus. In the apparatus, data representing read codes are generated and stored in a memory. A plurality of such data representing a user defined sequence of actions may be stored. Upon reading stored data, the apparatus can execute corresponding actions in the user defined sequence. Actions to be performed by the apparatus can include: starting, reversing and stopping of an electric motor; increasing and decreasing its number of revolutions; playing tones for generating melodies; and simulating everyday life sounds, such as the sound of a truck engine. The apparatus may be placed in a toy car or truck, in which it senses a tacho disc and synthesizes the sound of the truck's engine with a simulated number of revolutions corresponding to the speed with which the truck is driven.
