So, what exactly is this about?
Imagine: You are working on a project. You want to program in the Arduino language because of the simplicy. But you don’t want to use a 28 pin monster. Or you need peripherals like CAN or similar what the normal Arduino supported MCUs don’t have. So, what to do? Where are two alternatives:
1. Just don’t use the Arduino language and use things like bits and ports what you can’t understand.
2. Or continue reading this!

So, this instructable is going to show how to use the core files available from avr-developers.com. I’m also going to show you how to program the different MCUs and how to connect them to do so. At the end I’m going to give some ideas on what you can to with your new knowledge earned from this.

Blink_2_LEd_with_Arduino

This article is another step forward in learning more about Arduino. In our previous article, I have written in detail about blinking an LED using Arduino. We have demonstrated 5 simple led based projects using arduino, which will help you to learn its basic concepts.

In this blog post, I am providing you step by step instructions to build a very simple temperature and relative humidity meter for indoor use. All you need to build this project are an Arduino Uno or compatible board, a DHT11 sensor, and a MAX7219 based 8-digit serial 7-segment LED display. The temperature is displayed in degree Celsius and relative humidity in percentage.

When we learn a new programming language in computer science (say C, PHP or Java), we begin the learning curve with the classic “Hello World” program. We learn some essential keywords used in the programming language, then we learn the structure of the language and finally we begin to play with the language by making it display the two words “hello world” in our computer screen. So that’s how we begin to learn a programming language used to build computer applications. Our world of embedded systems is a little different. We create software to control hardware. In our world, we begin our learning curve by saying “hello world” using an LED. Our way of “hello world” is blinking an LED using the micro controller under study.

AVR

Microcontrollers are, without a doubt, amazing little things. They are versatile, powerful, and extremely tiny. Unfortunately, the latter trait is also shared by both my wallet and my programming skills. My understanding of C is poor, and I can hardly afford to buy something like an Arduino or a decent ISP. And in any case, the Arduino would be overkill for many of my projects, which only need simple IC’s.

But as many of you know, DIY always finds a way. This tutorial is meant for those among us with no budgets or programming experience who want to start using these little machines. It is not based around the ATmega328 (the Arduino Uno chip), but rather the Attiny line of chips (the Atiny85 and Attiny2313, to be specific). The total cost of this project can go as lower than $15 if you know where to buy from, and you can still use the original Arduino IDE and language to program your projects in the end. Keep in mind that you will need some soldering skills to get this project done.

SerialMonitor

ARPix has posted this instructable on constructing an external serial monitor device using the Atmega328 MCU and a graphic LCD. It allows a user interface to set the serial baud rate and start/stop functions using tact switches.

Sometimes I needed an external serial monitor like the Serial Monitor in the Arduino Editor, to see what is going on. So I made one. For the ESM I used an Atmel Atmega328 because it have an internal SRAM with 2KBytes. It’s necessary for the big data processing. So you need more than 1KByte SRAM.

I often use Arduino to test out my project prototype before complete it. Sometimes, I wanted to test more than one project at the same time. I would need more Arduino, but the original Arduino is over my budget for prototyping purpose. Therefore, I decided to make my own Arduino. Some of the benefits of making your Arduino (at least for me) are it is cheap, easy, learn to design PCB and electronics at the same time. Although there are a lot of guides on how to make your own Arduino, I decided to make one so as I can share with my readers, and at the same time document it for myself.

ZXLee built a simple sensor for Arduino which allows him to detect colors. The idea lies behind using red, green, blue LEDs and Light Dependent Resistor (LDR). Lee Zhi Xian writes:

Previously I have made a colour sensor using Arduino but don’t have the time to update it on my blog. Today I am going to share the details of this mini project. Basically, the sensor consists of three LEDs and Light Dependent Resistor (LDR). The LDR will detect the colour and display it to another RGB LED. Besides display it on the RGB LED, the colour will also display on PC. RGB LED is commonly used in display colours on LCD or OLED such as the monitor and television.

In this article, circuitstoday.com explain the basics surrounding arduino. As the title indicates, this article is for absolute beginners in the world of electronics and for people who are beginning with arduino boards.

Arduino is an electronics prototyping platform based on a micro controller. Arduino boards are usually made using Atmel’s Atmega series micro controllers or ARM micro controllers. Arduino is an open source hardware project which means the designs of board (the hardware architecture, CAD files) are available to public with open source license. Anyone can modify the hardware designs and the associated software.
