Physical Coding using Python

and Scratch

Coding is more important than performing front end stuff on the screen. You could also manage electrical equipment attached to the GPIO pins of your Pi using programming.

When people speak of 'programming' or 'coding,' they of10 think regarding software - and rightly so. However, coding can even be about much more than the operating system: it can significantly affect the world via hardware. This is termed physical computing.

Physical computing, as the title indicates, is very much about manipulating real-world stuff through your initiatives: hardware, not software. You are utilizing physical computing whenever you adjust the software to your washer, adjust the weather on your programmable heating system, or push a button at the traffic signals to cross the lane easily. Thanks to one major element, the Raspberry Pi is indeed a good product for studying regarding physical computing: the general-purpose input/output (GPIO) header.

Establishing the GPIO Header

Placed at the upper portion of the Raspberry Pi circuit panel and appearing like two lengthy rows of metallic pins, the GPIO header is to attach equipment such as light-emitting diodes (LEDs) and connectors to the Pi for command under the software you make. The term can seem somewhat complicated, but somehow it explains the part well. The pins can also be used for either input or output; they have really no defined function. They are recognized as headers whenever columns of pins are displayed on a circuit panel. Thus termed as general-purpose input/output header.
