Simple Arduino SPI Experience
.
In signal conditioning unit,
the output of the sensor may be amplified, filtered or modified to the
desired output voltage. For example, if we consider a microphone it
detects...

SPI implementation on Arduino
SPI stands for Serial Peripheral Interface and it is a way to send data between microcontrollers and other small devices. It is a synchronous data bus, meaning...
Arduino with 595
As my goal only to demonstrate different approaches I connected to LEDs only 4 out of 8 outputs of 74HC595.
595 Shift Register
595 series shift registers come in many flavors. SN74HC595 is the most usual.
There are many ways to drive multiple LEDs, which in sum would require...
