It’s hard to start this article. I’ve been playing with my new Arduino Starter Kit for a few days, and I think the best way to define it is: an electronic Lego<\/a>. An excellent toy for those who enjoyed the blocks years ago.<\/p>\n

<\/p>\n

Arduino is a microcontroller easily programmable from the computer using Arduino IDE<\/a>, where using C++<\/a> language, you can give intelligence to electronic circuits.<\/p>\n

But what makes it so interesting? Arduino is an OpenSource<\/a> project, meaning its operation and structure are public, so anyone can even build their own Arduino. This has allowed it to be available in many flavors and given it a large community of contributors who have made everything from libraries to tutorials for dummies.<\/p>\n

The image above shows the classic Arduino UNO<\/a>, but Arduino tools work on all existing varieties, including those seen in the photo below, where even on the right you can see one in the shape of a gamepad.<\/p>\n

You can connect an endless number of accessories to all of them, such as: buttons, all kinds of sensors, variable resistors, and lights. Whether analog or digital, you can somehow use them with this toy.<\/p>\n

Personally, I’ve been playing with my Arduino UNO for a few days, and my initial knowledge of electronics was only Ohm’s law. I want to share what you can achieve after a few days.<\/p>\n

Experiment N1: Change the state of the lights.

Experiment N2: Reading a pressed button.

Experiment N3: Change of state of variables using an input.

Experiment N4: Advanced state change.

The tutorial I followed to do this was the one available at this link<\/a>. The experiments are not exactly what they explained; in fact, in Experiment N4, I had to change the button resistor from 10,000 ohms to 100,000 ohms.<\/p>\n

I hope someone gets excited about getting into this world of electronics. I’m having a blast. If anyone has any questions, I’ll do my best to help you, just ask below.<\/p>\n

Cheers!<\/p>\n
