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.

The MicroView is the first chip-sized Arduino compatible that lets you see what your Arduino is thinking using a built-in OLED display.
You’ve never seen an Arduino™ compatible like this. With a built-in OLED (Organic Light Emitting Diode Display) you can see what your Arduino is thinking without having to connect it to your computer.
No more cryptic “Hello World” LED blink sequences or shoehorning oversized displays onto your tiny Arduino™. Development is much easier when you can see what’s going on.

This is a small keyboard to use with Arduino and works with Scratch:
This project starts a few months ago. Juan Brito, author of the blog Desafio Ecuador, contacted with me to talk about Scratch and the opportunities that gives this programming enviroment in the world of education. In his own words:
I and Danny Macancela are convinced that increase the quality of education in schools and colleges do not require big budgets by governments. This ideal of change has led us to develop this project to teach children mathematics and programming. Children can learn maths with fables. The aim of this project is the search of the human talent growth, which starts in the classroom. As Fritjof Capra says, ‘Today we have the knowledge, technology and financial resources to build a sustainable future. All we need is the political will and leadership’

LANp combines an LED RGB Bar from an old scanner, an Arduino and Ethernet/SD Shield to make a full RGB Lamp.
It has a built-in webserver that has an RGB colour picker, which changes the LED bar in real-time.
There is some photos and a YouTube video to show it all working.

The “EasyPlug Shield” for Arduino makes it super easy to connect sensors to your Arduino. The EasyPlug shield provides an incredibly simple, clean, and quick way to connect sensors to your Arduino board. They have sensors for just about anything.
All of our sensors are designed to be easy to use, right out of the box. Plug in a cable (provided) and the sensor is ready to go. We’ve picked the most useful and fun sensors for you. But we’re adding more all the time, so you should be able to find a sensor to fit your needs.

Small USB development board for Android. Smartphone powered, USB 2.0 communication, direct connection, open sourced API.
It’s an ARM Cortex-M3 development board that connects directly to your Android smart phone micro USB port. It’s powered from the phone so it has enough power for all sorts of applications without extra batteries, and when the device is connected to the phone the appropriate application starts up automatically.

hackshed.co.uk has a tutorial on how to interface a Nokia 5110 LCD to Arduino:
We purchased one of these very cheap, very cool 84×84 LCD backlit screens off of eBay a couple of weeks ago.
It’s a very nice product for adding visual elements to your projects at a very low price. We paid £3.89 for the screen and it was delivered a few days later.
Take a look below for connection instructions and example code from Adafruit on how to get this up and running with your Arduino.
