#17 - Arduino projekty: Keypad a robotická ruka

08/09/2014 21:57
Dnešní díl bude věnován praktickým aplikacím Arduina. V první části si předvedeme, jak pracovat s keypadem s dvanácti tlačítky. Vytvoříme si velmi jednoduchý zabezpečovací systém a také si ukážeme, jak si při programování zkrátit čas - vytvoříme si klávesnici pro programátory. V druhé části se dostaneme k servomotorům. Ukážeme si, jak se ovládají a poté si sestavíme kreslící robotickou ruku...

#16 - Náš první klon Arduina

11/07/2014 00:31

Po krátké odmlce Vám přinášíme další díl seriálu článků o Arduinu. V dnešním dílu si ukážeme, jak se dají pomocí Arduina programovat jiné čipy od Atmelu. Na začátek si předvedeme, jak pracovat s malými čipy z řady ATtiny, poté se dostaneme k větším čipům z řady ATmega a jak už název článku napovídá, vytvoříme vlastní klon Arduina.

The Crazyflie is a tiny open source nano quadcopter designed for hacking and flexible development. It weighs only 19 grams and measures 9 cm motor to motor. The development platform is open source. It’s designed with development in mind and has an expansion header that enables developers to expand the platform as well as good software development support. Its small size makes it perfect for developing new software. The Crazyflie can also be easily flown inside. Additionally, it is capable of lifting a payload of up to 5 - 10 g. Here is a CZ User Manual for Crazyflie Nano.

XBee Shield V2.0 is a stackable shield compatible with Arduino. It is easy to stack any modules from the Bee series onto it. You can easily build a wireless network for your project. The shield is also equipped with a function of level conversion, which enables a double-way conversion between high and low IO levels. The reserved digital pins facilitate users to select TX/RX port using jumper caps.

GPRS Shield - EFCom is a serial GSM/GPRS wireless module based on SIM900 4 Frequency GPRS module. This shield is compatible with all boards with the same form factor (and pinout) as a standard Arduino Board. You can the shield control via AT commands, SMS or phone dialing. In addition, EFCom supports LCD5110 display and serial keypad input.

The Arduino WiFi Shield is capable of connecting your Arduino to the internet wirelessly. The WiFi Shield can connect to wireless networks that operate according to the 802.11b and 802.11g specifications. The shield has an onboard micro-SD card slot. It is compatible with the Arduino Uno and Mega. The onboard microSD card reader is accessible through the SD Library. Arduino communicates with both the WiFi shield's processor and the SD card using the SPI bus (through the ICSP header).

2.8'' TFT Touch Shield V2.0 is a multifunctional Seeeduino/Arduino/Arduino Mega compatible resistive touch screen. It can be used as a sketchpad or a display device. Compared with the previous version, 2.8’’TFT Touch Shield V1.0, the screen driver has been replaced with a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Because of this change, programs developed for the original version need to be altered before being moved to the new version. Additionally, an SD card module has been integrated, so this shield reserves great room for other expansions to your project.

This wireless charging module can be used for close wireless charging or as a power supply. It can serve as a replacement for the Wireless Power Supply – it provides stable 5 V output voltage and maximum 600 mA output current.

Wireless Charging Module

This is a small and efficient DC/DC step-down voltage regulator that converts inputs between 3,2 V and 40 V into a smaller voltage between 1,25 V and 35 V. It is capable of driving a 3 A load with excellent line and load regulation.

Monster Moto Shield is essentially a ramped up version of Ardumoto Motor Driver Shield. The L298 H-bridge was replaced with a pair of VNH2SP30 full-bridge motor drivers. The support circuitry was also improved; this board is capable of driving a pair of high-current motors! The VIN and motor out are pitched for 5mm screw terminals (not included), making it easy to connect larger gauge wires.

The Wake-on-Shake combines the ADXL362 low-power MEMS accelerometer with the ATTiny2313A to allow your project to remain inert for long periods of time while waiting for a bump or a shake and sipping <2uA at 3.7V! Its power consumption is so low, that aging-related self-discharge of the batteries is most often the limiting factor for lifespan.

Wake on Shake

This comprehensive Arduino kit walks you through the electronic basics in a hands-on way. You build creative projects by learning using the most common and useful electronic components and with a selection of 15 projects that start from a low complexity, in order to let you learn the basic of electronic, to a major one, using components that let you control the physical world throw different kind of sensor. Once you have mastered this Arduino school, you have a palette of software and circuits that you can use to create something beautiful, and make someone smile with what you have invented, that is the reason why you find more components than the required from the projects of the book. Then build it, hack it and share it. Because Arduino is you!

The Arduino Starter Kit

This Sparkfun Inventor's Kit is a great way to get started with programming and hardware interaction with the Arduino programming language. The SIK includes everything you need to complete 15 circuits that will teach you how to read sensors, display information on an LCD, drive motors, and more. You don't need any previous programming or electronics experience to use this kit.

This gasketed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.
