Arduino Programming:-
For anyone new to the world of basic electronics, the first Arduino system might look somewhat cobbled together. But that's because it was!
Consisting of little more than an 8-bit Atmel ATmega168 microcontroller, a basic PCB, and a cable to connect it to a computer for programming, it was very 'rough and ready.
The first Arduino board
As a concept project, though, it was perfect -- the chip was very capable for the team's needs and also very cheap. You can buy them now for around $2 apiece!
Now, there's a whole host of different Arduino models to choose from: the basic Uno model, sporting another 8-bit Atmel microcontroller, to the likes of the Arduino Zero, which packs a 32-bit ARM Cortex chip and 256 kB of Flash memory.
You don't have to buy them pre-made; thanks to the open-source nature of the system, you can download schematics and make them yourself, too.
The popular Arduino Uno -- just $20
Each model comes with a number of analog and digital pins, for powering electronic components and sending/receiving inputs/outputs to and from the controller. The data pins are essentially 1 bit (a low or high voltage) but that's more than enough to use it to do a wealth of things.
For example, Uno can be easily hooked up to a digital temperature sensor and programmed to calculate the temperature, based on the signals received. Hence, this would have introduced you to Arduino IoT. To learn it in brief check out our Youtube Channel for a complete series of videos of Arduino.
