Another ATMEGA4808 Development Board turned out looking very well but highlighted some issues with supply and sourcing of components. Story ATMEGA4808 – An Improvement on my previous design? Or Not… When I first started playing around with the ATMEGA4808, I was impressed as well as disappointed by the Arduino Every “Clone” that I got online. […]

In this final part of the series, I look at the ATMEGA4808. This may just be the replacement for the ATMEGA328 that I have been looking for. Story The ATMEGA4808 provides a very attractive solution to replace the trusted ATMEGA328 or standard Arduino UNO /NANO. These chips are slightly more difficult to get hold of

Story This project is my implementation of an alien themed slot machine using two ATmega328P-PU micro-controllers. I was inspired by Cory Potter’s Alien Invasion Slot Machine, and I wanted to expand on that idea. The slot machine is for entertainment and educational purposes only. I tried my best to make the game simulate a real slot machine

Background I’ve written dozens of programs using the Arduino IDE and using other tools like the ARM mBed toolchain. My priority for this week was to familiarize myself with avr-gcc and the Atmel libraries. Week 4 Board Programming I had already programmed my Week 4 board with the provided serial echoing program so I was
In this step-by-step tutorial we will learn how to build a standalone Arduino UNO compatible ATmega328p board. ATmega328P Bare minimum configuration Before building our standalone ATmega328P chip Arduino compatible board, let’s take a look at the awesome Arduino UNO board and see the main components that used to build that beautiful thing. The first main

Project Introduction Our project is a spatial audio map of Collegetown that allows the user to use a joystick to virtually travel around the Collegetown crossing area and hear surrounding, directional sound. Our project takes inspiration from Street View, an interactive technology featured in Google Maps that provides users the ability to visually explore the
Introduction Sound Byte The Snorecorder detects snoring sounds from a sleeping person and records the time and intensity of each snore. The data is written to an SD card, which can be easily viewed on a personal computer. Synopsis The Snorecorder determines and records snore events and functions in two modes, “trigger” and “continuous”; Trigger

Introduction ProxiMIDI is a MIDI code generator, that takes its inputs from a user using Atmel’s Capacitive touch and Proximity technology. It can generate sound signals for 4 notes of 3 instruments and vary the tempo, volume and sound depending upon the proximity inputs. The signals generated from ProxiMIDI can be connected to any MIDI

What We Did We created an autonomous robot that explores the world in linear trajectories while avoiding obstacle using IR range-finding. The robot is a Venom RC car altered to be controlled by an Arduino Uno programmed in AVR Assembly (a very low-level programming language specific to the type of hardware used). The Arduino communicates

Introduction Printed circuit boards (PCBs) are the backbone of every electronic gizmo out there. They’re not flashy like those microprocessors, or abundant like resistors, but they’re essential to making all components in a circuit connect together just right. We LOVE designing PCBs here at SparkFun. It’s a love that we want to spread. It’s a
