[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a ...

The tester itself is relatively simple to build ... is hooked together, the NPN/PNP pair causes the LED to light up, but the circuit is broken whenever one of the transistors is removed.

The development board and the circuit board with the potentiometer from the Raspberry Pi Pico Experimenting Kit from Elektor ...

The diagram illustrates the basic design of an NPN junction transistor ... You’re going to build two simple transistor circuits, each using a single transistor. These circuits will allow ...

This transistor switching circuit uses an npn transistor, a voltage divider (consisting of a \(5 kΩ \) resistor and thermistor) and a \(5 V\) power supply. Use the information in the table to ...
