Control circuits for input and output

Control technology is an exciting new area for many schools and there are many commercial solutions available to solve the two main problems of how to control your motors and how to get your sensors to send suitable signals back to the computer. Just which computer and software to use is another problem. The range of equipment available for PCs for instance is enormous (and so is the cost in many cases!). For most other 16-bit computers there is little available, with the notable exception of the Atari ST (on which this article was written) with the Robokit, although even Apple is waking up to the possibilities of control work with the RESOURCE ‘Beeb-in-a-box’ add-on for the Macintosh.
