Programming an ATtiny w/ Arduino 1.0 This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are convenient for running simple programs. The ATtiny45 and ATtiny85 have eight legs and are almost identical, except that the ATtiny85 has twice the memory of the ATtiny45 and can therefore hold more complex programs. The ATtiny44 and ATtiny84 have 14-legs and more inputs and outputs. ATtiny45/85 vs. an Arduino Board The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. In short, then, if your project requires only a few simple inputs and/or outputs, you’re probably fine using an ATtiny. Materials and Tools For this tutorial, you’ll need: An in-system programmer (ISP), a piece of hardware used to load programs onto the ATtiny. For more information, see our list of materials and parts and our list of prototyping supplies. Connecting the ATtiny
Entwicklerplatinen: Arduino Esplora ersetzt das Breadboard Mit dem Arduino Esplora ersparen sich Bastler Lötkolben und Steckplatine. Die Entwicklerplatine hat ähnliche Hardware wie die Platine Leonardo und ist zusätzlich mit diversen Sensoren, Schaltern, Steuerelementen und sogar einem Joystick ausgestattet. Das Design orientiert sich an herkömmlichen Gamepads und lässt sich auch so nutzen. Der Mikrocontroller ist mit 16 MHz getaktet und hat 32 KByte Flash-Speicher, wovon 4 KByte vom Bootloader belegt werden. Die RX- und TX-LEDs auf der Platine zeigen die Datenübertragung vom Esplora auf einem Rechner an. Gamepad mit Sensoren Neben dem Joystick mit zentralem Druckknopf hat der Esplora auch vier Schalter, die rautenförmig angelegt sind. Für die Softwareentwicklung gibt es eine Bibliothek, über die sämtliche Komponenten des Esplora angesprochen werden können. Ohne Versand kostet der Arduino Esplora 42 Euro.
Arduino unveils Arduino SIM – a new cellular connectivity service for Arduino IoT Cloud Arduino has today launched Arduino SIM, a SIM-only service exclusively for IoT (internet of things) devices based on the Arduino platform, to give developers and manufacturers cellular access to the Arduino IoT Cloud platform from over 100 countries with a single data plan and competitive pricing. Arduino SIM aims to provide the simplest path to cellular IoT device development in an environment familiar to millions. The cellular service, provided by Arm® Pelion™ Connectivity Management, means a single physical Arduino SIM can be used in over 100 countries worldwide with one simple data plan. The Arduino SIM data plan is launching initially in the US, with availability in Europe and Asia to follow in summer 2019. New security-focused Arduino boards Arduino SIM is initially rolling out with support for Arduino MKR GSM 1400 (3G with 2G fallback) – a 32-bit Arduino board supporting TLS and X.509 certificate-based authentication through an on-board secure element and crypto-accelerator.

Thingiverse - Digital Designs for Physical Objects Lab3 - Laboratory for Experimental Computer Science Watchdog and Sleep functions This example shows how to make use of the Watchdog and Sleep functions provided by the ATMEGA 168 chip . These functions are useful if you want to build low power consuming devices operated by battery or solar power. The reduced power consumption is achieved by through a intermittent operation of the system .In case of Arduino your main loop will be executed once before the system is put into the sleep mode. When we assume that the time to measure a sensor and making some decisions will take 10 millisecond and the watchdog is set to 8 seconds the on/off ratio is 800 which extends the battery live time by this factor. Battery live time calculation Now we want to know long we can operate our device with standard alkaline AA Cells. In normal operation with a current of 20mA the battery will last 2000/20 = 100 hours or about 4 days.

Best of 2012: Arduino Projects As 2012 concludes, let’s look back at all the cool Arduino projects that we’ve featured on the site. There were a ton! We’ve been big fans of the Arduino since its release, and there are hundreds of posts on the blog as a testament to this love affair–with more to come in 2013! The following are some Arduino projects from 2012 that I especially liked: A Hacked Jaminator Band featuring an entire band of Yamaha Jaminator keytars! How cool would it be to have your own How-To: Build a Room-Sized Skill Crane? Pages: John Baichtal My interests include writing, electronics, RPGs, scifi, hackers & hackerspaces, 3D printing, building sets & toys. Related
DIY Self Balancing Robot using Arduino After being inspired by RYNO motors and other self balancing scooters from Segway, I always wanted to build something my own Arduino Segway Robot. Thinking for while, I decided to build a Self Balancing Robot using Arduino. This way I would be able to grasp the underlying concept behind all these scooters and also learn how PID algorithm works. Once I started building, I realized that this bot is a bit of a challenge to build. There are so many options to select from and hence the confusions start right form selecting the motors and remains till tuning PID values. But let me break it to you, once you build it you will agree that it’s not as hard as it sounds to be. Selecting the Parts for Self Balancing Robot Before I tell you all the options for building the bot let me list the items that I have used in this self balancing robot project Arduino UNOGeared DC motors (Yellow coloured) – 2NosL298N Motor Driver ModuleMPU6050A pair of wheels7.4V Li-ion BatteryConnecting wires3D Printed Body
Very low power LED firefly This is my version of an LED firefly, built with what I think is the smallest parts count and drawing the least amount of power that I can. Here is the entire parts list: 1 ATtiny13a MCU 1 Green LED (diffused lens works best) 1 1 Mohm, 1/8-watt resistor (1/4-watt works also, of course) 1 CR2032 coin-cell battery 1 CR2032 coin-cell battery holder Naturally, the MCU spends most of its time in sleep mode to keep the power drain down. Additionally, the MCU does not turn on the LED unless the light level is dark enough. The power draw for this device is below my ability to measure. Here is a group of three LED fireflies. Here is a closeup of the firefly wiring; pin one on the MCU is to the left. I used a Renata CR2032 battery holder with through-hole tabs, turned upside down, as a base for the firefly. It only takes about ten minutes to build up a firefly. Note that you want to use a diffused LED for this project; the LEDs with water-clear lenses don't let you see much of the blink.
Quarta revolução industrial: A Era das Máquinas Livres "Faça você mesmo científico" O movimento "Faça Você Mesmo" saltou das tarefas domésticas para os laboratórios de pesquisa. E o salto foi impulsionado pelos mesmos motivos: economizar dinheiro e obter exatamente o resultado que você deseja. Para Joshua Pearce, o "faça você mesmo científico" está dando início a uma revolução. Três forças convergentes, todas de código aberto (open-source), estão por trás dessa revolução, explica o pesquisador em um artigo publicado no número mais recente da revista Science: software, impressoras 3D e microcontroladores. Com essas ferramentas, pesquisadores de todo o mundo estão reduzindo o custo de fazer ciência, construindo seus equipamentos no próprio laboratório. Arduíno Tudo está sendo possível graças ao microcontrolador open-source Arduíno. "A beleza desta ferramenta é que é muito fácil de usar," disse Pearce, que é professor da Universidade Tecnológica de Michigan. Veja como funciona.
