Arduino as ISP or how to burn bootloader

Often You need burn bootloader onto ATmega chip. You can always buy chip with preloaded bootloader or ISP programmer like USBASP, however any working Arduino can be used as one. You can do as follows: download ArduinoISP sketch in working Arduino (menu File/Examples/ArduinoISP) as any other sketch connect chip in following way (on right are […]

P4A – PHP for Arduino part 2

In the previous post we’ve finished with reading files from SD card. Now we have to pass them through our PHP :) and send the results to the client. To make whole process more simple, we’re assuming each of the files is known to us. This means, we’re registering every file (URL) with addCommand. How […]

P4A – PHP for Arduino part 1

If you already know Arduino stuff a bit, maybe you want to connect it with a network somehow. It could be some network-enabled home automation solution or a set of sensors sending data to a database. So, here comes the Ethernet Shield to help you. First, a bit of history. Initially, the Ethernet Shield was […]

A documentary movie about Arduino

Here’s a really interesting documentary devoted to Arduino project. It explains how the idea began and why its creators decided to spread it out freely. There are also demonstrations of some smart devices based on Arduino. You can watch it on the Arduino Documentary page in english (except for some spanish snippets, english subbed) or […]

Puff – The Magic Firefighter

This is Puff, Magic Fire Fighting Dragon Puff consists of: Arduino chassis and two motors servo moving its head motor with a fan two photoresistors as fire detectors The result? Autonomic robot (this means, controlled only by software from Arduino) detecting fire (this means, a bright light) and trying to put it out. It recognizes […]

Programming the Arduino Pro Mini with USB Mini

Everyone, who has been making a project based on Arduino probably wanted the board to be smaller than the basic unit. A variety of smaller, but compatible with Arduino, boards have been developed. One of them is SparkFun’s Arduino Pro Mini. Currently, it has ATmega328 onboard and its dimensions are 33 mm x 18 mm. […]

Remember the colours – a game

The following article is based on this entry on Newton’s blog (in Polish). All the pictures, program code and the video clip came from there. This project’s goal was to use as many parts from the Arduino Starter Kit, as possible. So, what is this project exactly? As the title itself suggests, it’s a game, […]

How to connect switches

Switches (buttons, pushbuttons, tact switches) are commonly used with Arduino. But, for beginners, it’s sometimes irritating when it comes to wire them up correctly. Some of their terminals are shorted with each other. Such a switch doesn’t work if putted in reversely. Because of that, here’s some words of explanation. For instance, we have a […]
