Semiconductors
Resistivity
According to Ohm's Law, the electrical resistance
of an electronic device is defined as the ratio of the potential
difference across the component to...
Use BJTs
Transistors are 3 terminal semiconductor devices which is able to
conduct relatively high power across their two terminals, in response to
a significantly low power input at the third...
Connecting BJTs and MOSFETs
The interfacing of power devices like BJTs, and MOSFETs with Arduino
output is a crucial configuration which allows switching high power
loads through low power outputs of an Arduino.
DC Biasing in BJTs
In simple terms, biasing in BJTs may be defined as a process in which
a BJT is activated or switched ON by applying a smaller magnitude of DC
is...
595 Shift Register
595 series shift registers come in many flavors. SN74HC595 is the most usual.

Introduction
A single, analog signal to drive a string of 10+ LEDs, which can be configured into either bar mode (where all LEDs below a certain...
Termistors, how they work
A thermistor is a semiconductor temperature sensing
module, its value of the resistance is larger than the conductive
substances and less than the insulators. The materials used for the...
