Ever wondered how a simple transistor can power an entire computer and run complex code? Discover the amazing world of ...

The electronic touch switch circuit require few external components ( four transistors and four resistors ) and is very simple do build even for beginners . Very simple electronic touch switch – ...

The transistor acts like an insulator or a switch that is turned off ... You’re going to build two simple transistor circuits, each using a single transistor. These circuits will allow you ...

This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...

A very simple but highly efficient combination lock circuit is shown in ... state "0") to prevent grounding the transistor's base. Setting any of these switches to "1" grounds the transistor's ...

Q1 is a simple PNP transistor acting as a pull-down switch until C1 charges and switches ... unplug and replug scenario will leave C1 charged and the circuit in effective. Are you sure there's ...

The switch circuit consists of two basic components ... With the addition of a simple transistor and a resistor on its base to limit current, we can invert the signal needed to turn on the ...

Thermocouples and their leads often have to detect open-circuit or short-circuit faults. However, it is very difficult to distinguish a valid millivolt temperature signal from an open/short ...

When they first came on to the scene in the 70’s, the single button soft switches were built using a set of transistors and ... of the switch is fairly simple, though he did run into some ...
