The DFRduino Nano USB Microcontroller V3.1 (ATMega 328) is a breadboard ready version of the Arduino mini with integrated USB. The Nano has everything that the Diecimila has (electronically) with more analog input pins and an on-board +5V AREF jumper. The Nano automatically senses and switches to the higher power supply, so there is no need for a power select jumper.
The nano's pin layout works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other). The DFRobot DFRduino Nano USB Microcontroller V3.1 (ATMega 328) can be powered via the mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

- Potentiometers and the Arduino Uno
Variable resistors come in all shapes and sizes, and they all do the same basic job. They allow you precisely control voltage/current flow within a circuit. The most common type of variable resistor we see in DIY electronics is the Potentiometer, or ...

If you could operate your switch without physically toggling it on and off, you would open yourself up to an entire section of electronics. Relays are one of the best ways of doing this. A relay is essentially just a switch, controlled by an electrom...

Hey guys! First time poster. I've been working on a blaster for my girlfriend's costume, and I thought I would share it with everyone. When triggered, it plays a selected sound effect and flashes the light. Pretty simple :)
- Coffee Grinder With Arduino
Using a few bits and pieces, this ordinary coffee grinder now has two presets to run the motor for a programmable length of time. The idea being that the grinder running for a set amount of time will deliver a certain amount of coffee each button press meaning the beans can be stored unground, keeping them fresher for longer. I completed this project for a friend, Ian, who lives for coffee. Ian wanted the same functionality in h...
- The Hipster Coaster
We wanted to make a interactive display of the fun that can be had with DIY projects to take to Sydney Mini Maker Faire. We decided to do so by utilising the TinkerKit Braccio from Arduino.org, alongside some 3D Printing ingenuity, for an engaging display for all ages. Enter the Hipster Coaster in all its glory. All the parts were printed seperately on our family of Lulzbot 3D Printers, later stuck together using a mi...
