Arduino: Introduction

 The Arduino is a collection of components that work very well together.

Some important features are the Arduino Uno, Digital and Analog I/O, Programming, Libraries, Sensors, Actuators, and Integrated Development Environment.

Then, we talk about prototyping.

The, the programming environment. This is where you learn about LEDs, resistors, and potentiometers, the most used components. 

Then there is implementation if the form of experience, such as detecting visible ultraviolet light and color.

After this, we learn about environment sensors and the movement and orientation so the gadgets know when they move. Then, we can make noise and make the arduino aware about the world around it.

Finally, we can display messages through the liquid crystal displays. Gaining knowledge means gaining independence.

Most importantly, we have the confidence of knowing that we can learn on our own, and we'll be able to create intruder alarms, LED cubes, environment monitors, among more.

There are absolutely basic and necessary course that are needed to reach Arduino. Obviously I need a soldering iron.

You need solder for a soldering iron, and there is a difference between leaded and lead-free solder. Leaded solder has much more health risk and implications, get lead-free if you are a younger person. I will need a contraption holding hands, that allows the securing of a device working on, so I can go ahead and do the soldering without having to change parts. So I get some kind of device to hold the board in place while doing the soldering.

Then I use breadboards, either a mini or micro soldering board. I can combine small breadboards when I need a little more real estate. 

Desolder removes solder from the part so that the part can be repaired, and it sucks the hot solder so it can remove it from the breadboard.

Small precision screwdrivers are necessary and some parts have potentiometers for calibration, and I need a screwdriver to be able to operate these small parts and potentiometers. Any small precision screwdriver will do. Then we need wire cutters to trim the soldering work done from a PCB. Sometimes we need to attach the header and solder it on. 

Tweezers are also very helpful since I am able to place parts, and these are magnetic and antistatic. Then we need lots of wires. Most wires are male to male but some are other types. Male to male are sticks on both sides. We never want to run out of jumper wires. 

Last but not least, we will need a very simple multimeter. We can try to find autoranging multimeter or other types. Those are the tools needed. Now, to the parts. 

As far as the components, this is everything you need. We'll be starting with the Arduino Uno, for people just starting with their adventures, and purchase a genuine Arduino. This is the first and most important part that I need for this course, and the second thing that is needed is a breadboard, with photoresistor (enables light detection), Thermistor (analog component to detect temperature), TMP36 (also used to detect temperature) and certain LEDs. 

Then RGB color LEDs make it possible to produce any color imagine, since it's got 4 pins RGB buttons. 

Potentiometers are used to produce analog outputs, and any sketch on the Arduinos. 

3V batteries are used to test LEDs and stuff. Then there are microphones, and you can use them to help the Arduino to detect sound. There's both analog and digital microphones. There are several light sensors, one detects ultraviolet light and the other TCS34725, detects the color of the object right in front of a sensor. Still, the passive infrared sensor allows us to detect a hot object in front of a sensor. 

Environment sensors are very popular among individuals, the BMP180 and BMP280 to name a few sensors. The MCP9808 is a very accurate temperature sensor. 

The ADXL335 are sensors that detect movement, that got many different types of features and characteristics. 

For detecting digit there is HC-SR04, an UV distance commodity sensor. 

We'll be using buzzers for making noise. These can be used for making music or different tones. Finally there are LCD screens.

These can display a lot of text in a number of columns. The easiest way is through a parallel connection, which requires a lot of pins to be occupied. This is why an adapter PCF857T LCD adapter works for this.

The backpack converts the parallel interface to a serial interface. The shield from adafruit connects onto an arduino can be soldered. There are lots of buttons that can create a nice user interface for the gadget.

Finally, I need tons of resistors, with certain values to use as pull downs and pullups (10KΩ) and 120Ω to power LEDs. 

Schematics help us through the wiring process.

You can also read Wikipedia, then subsequently resume with watching the lecture. Just do all exercises, lol. Another type of question is an opportunity to find mistakes, which help to stretch knowledge and brain muscles, serving as an effective way of learning. Include as many details as you can in the question.
