Yes, there is a chance to realize one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the little circuit ...

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...

PNP transistors and n-channel transistors function similarly to “signal turns switch on” relays and tubes; likewise NPN transistors and p-channel transistors function similarly to “signal ...

Buzzer Basics: Technologies, Drive Circuits, and Live Sound Demos The positive temperature-coefficient (PTC) thermistor in the pnp transistor’s current-control circuit prevents short-circuit damage.

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR gate… ...
