We can make a simple touch switch using only two inverter gates, two resistors, and two capacitors. The schematic diagram of the circuit is shown in the figure below. At power up, the output (of U1A) ...

Working on an embedded project? An 8-bit microcontroller with a pulsewidthmodulation (PWM) peripheral can provide a low-cost and easy solution to adding natural voice to your next embedded endeavor.

I designed this relay circuit to function as a DPDT toggle which is controlled by a momentary switch. I strive to keep my circuits simple with little or no integration (555’s, transistors, etc). The ...

USB toggle switches make it possible to connect one USB device to multiple computers. Though the connected device can't be used with all the computers simultaneously, you can toggle between the ...

We all have too much stock of one component or another. Maybe you have more audio pots than you know what to do with, or maybe it’s zener diodes. For [technologyguy], that thing is a pile of toggle ...
