Schematic I2C Rotary Encoder Posted by Willem Aandewiel Website Willem Aandewiel (1955) has a background in electronics and digital techniques. However, most of his working life he has worked in automation where he has worked in just about all disciplines from programmer to project leader and project manager. Willem was one of the first Dutchmen with a micro-computer (KIM-1, 1976) at a time when the PC had yet to be invented. Nowadays he is mainly concerned with the design and production of small electronic circuits with microprocessors. His 'mission in life' is to make people enthusiastic about making their own electronic circuits, microcomputers and programming.
