many of which have simple circuit-based on/off control for lights. [Paulo Borges] has created something quite different, however, with his in-the-wall servo-controlled light switch. This build ...

The other requirements for the project were to use a microcontroller and to keep it simple. [Vadim] chose an ATtiny2313 to handle the RC-5 IR protocol and switch the light. The circuit still has ...

the switch will close, setting off our alarm! Practise drawing the following series circuits using symbols: A simple circuit with a bulb and battery. A series circuit where the bulb doesn't light ...
