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 – source. The circuit as you can see from its diagram is ...

Figure 1: Simple threshold circuit – which does not work with some references! When I designed this circuit I assumed that if I used 1MΩ as R fb the current ... These domestic maker circuits are not ...

Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop. All that’s needed for both outputs is an Arduino and an ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transis… ...

If you need to design a control circuit for your FPGA-based DSP system, these simple techniques could save you days of work. By Narinder Lall and Brad Taylor, Xilinx, Inc. ... Although much has been ...
