Need more Arduino board? Do not spend more money for another one. Why not try to build your own DIY Arduino board? It is easy and simple. DIY Arduino Step 1 Get an Atmega328–PU or Atmega328P-PU (with bootloader inside). atmega328p A brief introduction on the Atmega328 chip: 8-bit MCU 32kB Flash Memory 1kB EEPROM 2kB […]

This how-to takes you through all the steps of making your own arduino on a perfboard or perfduino! Arduino microcontrollers are great for learning about physical computing and are very useful for rapid prototyping. Arduino’s simple programming language makes it a favorite of hobbyists and diy-ers around the world. Because arduino boards range in price

The DIY industry is booming, despite the desperate blackmailing of society by finance capitalists. Companies like Adafruit and Makerbot are grossing well over a million dollars a year, and Evil Mad Science Laboratories just recently dedicated themselves to running a full-time kit business. Making kits is fun, but starting a business can be scary. If

In this introduction I will show you a overview of this project whit Arduino Uno. The purpose of this instructable is move a electric roller shutter by Arduino Uno. The prototype that I made is my first electronic project with Arduino and I hope this instructable and the solutions that I found are useful for

I got my start in microcontrollers with the Arduino, as many of us outside of electrical engineering did. (And still do!) The ease of programming that little board makes it a great gateway… and like any gateway, sometimes you go through. Most of my projects now don’t use Arduinos directly. For simple microcontroller applications, it’s

Here’s a simple Arduino-based datalogger I’m currently developing: This test-of-concept model is based on the Arduino Pro Mini (ATMega168). It runs on a 1.5-V battery, using a voltage up-converter from Sparkfun.com. For a sensor, it’s using a 3-axis accelerometer on a breakout board, also from Sparkfun. It has one button for control. When the device

I’m teaching “Electronics for Scientists” this semester, and I wanted to allow each student to have their own Arduino to play with for microcontroller lab exercises and possibly use for their final projects. The Arduino is not very expensive at roughly $30 per, but they add up quickly when you have a whole class of

Ah yes, it’s time for another Instructable involving an Altoids tin… But this time it’s not about what’s inside the Altoids tin, it’s about the Altoids tin itself. In all its greatness, the Altoids tin we all know and love has one rather major flaw for DIY electronics use: it’s electrically conductive. To combat this,
Electrically Insulated Altoids Tin Continue Reading
This example simplifies the task of collecting data from the Esplora’s accelerometer and graphing it with your computer. The Esplora sends keypresses to a connected computer about the state of the accelerometer. If you open a spreadsheet application, you can log the data from the accelerometer. To start and stop the datalogging, press the down

The Haptic Proximity Module (HPM) seeks to enable people with low vision, or other vision impairments, to engage with their direct surroundings through vibration feedback from a range detector, and do so cheaply with readily available components. The aim of this instructables is to share the parts and process of creating this device in the
