Arduino with Python

Introduction to Arduino

Just to get out of the comfort zone when programming only in Python may be worthwhile. Arduino is a soft introduction to electronics, not without its own difficulties - but nevertheless enjoyable. Unless you have a specific goal in mind it is probably a good idea to start with a complete starter kit with an Arduino, breadboard, several modules and electronic components, a good sized multi-compartmented box cables and instructions.

What they don't tell you is you will need reading glasses, a magnifying glass, strong tweezers and a good lamp. You will also need the patience of Job, the strength of Samuel and tiny fingers.

Some suppliers such as Elegoo made a good offer with a good supply of materials. Their instructions were basic but none too exciting, but you could get a feel how each module functioned. There were three motors, one normal, one stepper and one servo motor and a power supply unit to drive them. If there was a suitable mounting system running both motors perpendicular to each other would produce an interesting experiment.

To progress further one needs a lucky break when searching the Internet, that or a good text book. The more advanced work mainly concerns robots, which requires a fair bit of hardware. The other route many take is to use the Arduino with its breadboard as a prototype, in the end scaling down with smaller integrated circuits, such as a micro Arduinos, or even just the main chip. Cleverer users may be able to replace the Arduino completely by electronic parts, still the lessons learnt with the Arduino and its sensor modules should be invaluable.

Part of the learning is the ability to relate to the results made with various sensors. The software that Arduino comes with is the Arduino IDE and this will be addressed further in IDE Fundamentals.
