This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

This simple design produces a sinewave that ranges from 2Hz to 20Khz using a CypressMicro PSoC chip. More information on these versatile devices can be found on their web page at: If we set f to 1Khz ...

Connecting an LVDT (linear-variable-differential transformer) to a microcontroller can prove challenging because an LVDT requires ac-input excitation and measurement of ac outputs to determine its ...
