A Beginner Guide for Arduino

Arduino is a revolutionary open-source electronics development platform based on easy-to-use hardware and software. Arduino boards are able to read inputs — light on a sensor, a finger on a button, or a Twitter message — and turn it into an output — activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

There are a plenty of resources available online to learn and work with Arduino boards. Here we have compiled a list of tutorials in a logical manner so any beginner can learn the concepts of Arduino and can have hands on experience of it. So, let’s get started…

You should know exactly which arduino board is perfectly fit for your projects, which Arduino board has the features to make the smart device as you want. Know more about them here — Different types of Arduino Boards

3. Different ways to Power your Arduino

How many ways there are to power your Arduino Boards? It will be helpful to know every possible way to charge Arduino boards. When you need to power your Arduino, you can use an alternative way to bring the energy to Arduino. Best way to Power Arduino Board

4. What is Arduino IDE and Arduino Programming

In the world of IoT and technology, you need to smart your Arduino boards, you have to program them and Arduino IDE is the software where you connect and program your board. This development IDE feature as code editor compiler, programmer, serial console, and serial plotter. This has a simple and easy to use interface. — Beginners Guide to Arduino IDE

5. Arduino Timer Tutorial

Now it’s time to know how to use Arduino boards for your systems, and how numerous features it has on them. First, start with Timer. Timer is kind of interrupt. It is like a simple clock that can measure time interval of an event. In Arduino UNO, there are three timers for different functions.

Timer0 — It is an 8-Bit timer and is used in timer functions such as delay(), millis().

Timer1 — It is a 16-Bit timer and is used in the servo library.

Timer2 — It is an 8-Bit Timer and is used in the tone() function.

6. Arduino ADC Tutorial

After the timer pin, move on to the ADC pin. The Arduino board has six ADC channels, these can be used as inputs for analog voltage. The ADC of Arduino Uno is of 10-bit resolution. It means, it will map input voltages between 0 to 5 volts into integer values between 0 to 1023. This project will help in analog to digital conversion.

7. Arduino SPI Communication

Another pin on Arduino — SPI Pin is used for the SPI communication between two Arduino boards. Now, learn to do SPI (Serial Peripheral Interface) communication using Arduino SPI pin. SPI is a serial communication protocol. In serial communication, we send one-bit data through a communication channel.
