Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

These domestic maker circuits are not particularly novel, but they do illustrate some uses of references and op-amps in simple analog control and measurement – and in particular highlight a problem ...

Systematic methodology is the key to quickly and effectively troubleshooting control circuits. Even the most experienced troubleshooter must rely on a systematic troubleshooting process to solve ...

Two process control signaling schemes were to be supported ... The current loop output is only slightly more complicated. An identical circuit on a separate Arduino output generates the ...

Although much has been written about how to use FPGAs as signal processors, not much has been published about building control circuits within such systems. There are perhaps two key decisions to make ...

Nevertheless, a single-adjustment tone control often can be useful for fine balance adjustment or where multiple controls are impractical or unnecessary. A simple ... the circuit would be ...
