When all the prerequisites are installed, hardware setup can be performed.
For this purpose, a simple circuit is built using a breadboard and a few electronic components.
A Complete Guide to Understanding This Blockchain Concept
The hardware components are listed as follows: LED: The abbreviation of Light Emitting Diode, this can be used as a visual indication for an event.
Resistor: A 330 ohm component is required which provides resistance to passing current based on its rating.
It is not necessary to understand the theory behind it for this experiment; any standard electronics engineering text covers all these topics in detail.
Breadboard: This provides a means of building an electronic circuit without requiring soldering.
T-Shaped cobbler: This is inserted on the breadboard. photo and provides a labeled view of all General Purpose I/O (GPIO) pins for the Raspberry Pi.
Ribbon cable connector: This is simply used to provide connectivity between the Raspberry Pi and the breadboard via GPIO.
