I am going to save us a lot of bullshit and just jump into one of the main koko of the thread- how to use an Arduino board. Wait!! Do you know what an Arduino board is? Hahaha!! Sounds funny and ridiculous – I know. But no offence!! Even Sheldon Cooper doesn’t know everything! Let us briefly talk about it. Arduino is a microcontroller development board. A microcontroller is an IC (Integrated -circuit) that is really smart. It has its own memory inbuilt and quite small- since it is actually a more specific something. A microcontroller works on the principle of logic gates and ….well; let us just stop there for now. Have you ever wondered how eateries and shops and supermarkets do their this ‘sliding message’? have you ever wondered how the car key remote works or how the automatic pumping machine works? Or how the DVD know where you stopped the particular disc or how a microwave knows that a particular temperature has been reached and should make a sound and display the status? Well, like I promised, I am here to do my best in clearing these ‘HEADACHES’ you have been having. The answer to all of the above is something we call: A MICROCONTROLLER. It is small and have some legs (some have just 6 while some have over 30) and can be used for virtually any cool thing you can think of. The problem however , with microcontrollers is that it does a specific job and its memories (RAM and ROM) are very much limited and so small that they are most measured in ‘kb’ (kilobyte). Imagine your PC having a 1kb RAM/32kb ROM. Funny!! Luckily, your PC has a microprocessor not a microcontroller. Instead of having its memories built in, it has a RAM slot and HDD-Hard disc drive or SSD – Solid state drive SSD. A microprocessor also has the ability to do many things at a time. These are the direct opposite of a microcontroller, and are the major differences. So our dear Arduino is one of these. As time goes on, we will see more wonders of Arduino/microcontrollers.
