CIRCUITO.IO: A Platform for idea Development

Arduino is an open source hardware and software company that creates Single Board Controllers (SBC) and Microcontroller kits, and these kits come in a Do-It-Yourself (DIY) form. Arduino can be used by almost anyone because it is inexpensive and also easy for professionals and even amateurs to use. Despite the fact that Arduino kits come in a pre-assembled manner, one can get stuck trying to think of ideas f ...

CASUAL TETRIS COMES IN AT $9

[Michael Pick] calls himself the casual engineer, though we don’t know whether he is referring to his work clothes or his laid back attitude. However, he does like to show quick and easy projects. His latest? A little portable Tetris game for $9 worth of parts. There is an Arduino Pro Mini and a tiny display along with a few switches and things on a prototyping PC board. [Michael] claims it is a one day bui ...

Arduino-Using Shift Registers With Ultrasonic Sensors

The HC-SR04 Ultrasonic range sensing module is great for sensing distances that can be used as an input for your Arduino projects, but using multiple (more than two) can quickly cost you a lot of pins. This basic Instructable gives you the code and basic instructions to use the 74HC595 8 bit series to parallel shift register so you can connect up to 8 HC-SR04 modules (16 IO pins) while using only 4 Arduino ...

OTA FLASH TOOL MAKES FITNESS TRACKER HACKING MORE ACCESSIBLE

Over the last several months, [Aaron Christophel] has been working on creating a custom firmware for cheap fitness trackers. His current target is the “D6 Tracker” from a company called MPOW, which can be had for as little as $7 USD. The ultimate goal is to make it so anyone will be able to write their own custom firmware for this gadget using the Arduino IDE, and with the release of his new Android ap ...

Smart Kitchen Cube

Alexa controlled timers at a glimpse. A really fancy egg-timer with added temperature control. Story Idea Both of us like to tinker with electronics and the latest hard- and software. While most projects never get out of "early-Alpha", we wanted to create something with a prototype look&feel for quite a while now. Participating in The Alexa and Arduino Smart Home Challenge finally made us consider creat ...

LED Matrix Controller

In this project, we will use the digital pins and screen of the 4Duino to create a 5×7 LED matrix controller with a user graphical interface. An LED matrix is essentially many LEDs packaged in a dot grid format in order to produce pictures or large text. They’re commonly used for signage purposes in the public space. The LED matrix utilised in this project is made by multiplexing 35 LEDs together such that ...

Arduino Lab 2 – Morse Code Generator

Introduction An excerpt from OmniGlot.com about the origin of Morse Code: Morse Code was invented by Samuel F. B. Morse (1791-1872), a painter and founder of the National Academy of Design. He conceived the basic idea of an electromagnetic telegraph in 1832, and produced the first working telegraph set in 1836. This made transmission possible over any distance. The first Morse Code message, "What hath God w ...

Arduino Ping Ultrasonic Range Finder Code

The Ping))) is an ultrasonic range finder from Parallax. It detects the distance of the closest object in front of the sensor (from 2 cm up to 3m). It works by sending out a burst of ultrasound and listening for the echo when it bounces off of an object. The Arduino board sends a short pulse to trigger the detection, then listens for a pulse on the same pin using the pulseIn() function. The duration of this ...

Arduino Keyboard and Mouse Control Code

This example illustrates the use of the Mouse and keyboard libraries together. Five momentary switches act as directional buttons for your cursor. When a button is pressed, the cursor on your screen will move, and a keypress will be sent to the computer. Once you have the Leonardo programmed and wired up, open up your favorite text editor to see the results. NB: When you use these libraries, the Arduino tak ...
