learn.adafruit The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better. We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! Lots of other little improvements such as a polarity protection FET on the power pins and a big prototyping area. Lets check out these specs again: 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter!

How to control a Servo In this one, servo is programmed to be controlled by two buttons, one turns servo to the left and the other one turns it to the right. When the servo is turning, corresponding LED will be switched on to indicate the operation. Result: Because Arduino has built-in library for controlling servo, which makes servo a really easy kit to use. In this project, I will be using a servo to turn the IR sensor around constantly. This is the circuit Diagram: This is the code: #include Servo myservo; // create servo object to control a servo // a maximum of eight servo objects can be created int pos = 90; // variable to store the servo position const int maxDeg = 160;const int minDeg = 5; const int leftPin = 3;const int rightPin = 2; const int led1Pin = 6; // indicatorconst int led2Pin = 5; // indicator const int outputPin = 9; // pwm function will be disabled on pin 9 and 10 if using servo int leftPressed = 0;int rightPressed = 0; If you find this article useful.

Arduino Shield List: Samurai Circuits Mama Shield Photo by Tully Gehan Shield URL: Mama ShieldTags: Maker: Samurai Circuits The Mama Shield was designed for high-speed prototyping, and has 5 slots for inserting daughter-boards. Each slot has a 36 pins. The slots contains all of the Arduino pins plus 8 shared bus pins. The bus pins allow cards to communicate between each other. The shield also has a switchboard so you can easily reconfigure the pin mapping.

Microsoft on Wednesday began the long, long process of trying to make the world forget all about the disaster that was Windows 8. By all accounts, the company has done a good job so far, not just by skipping 9 and jumping right to 10 for the software’s name, but also by creating a new operating system that actually seems like it was designed to run on a laptop or desktop, rather than just a tablet. While July 29th marks the start of the Windows 10 rollout, there’s no guarantee that you’ll get the new software today — or even this week — if you sit around and wait for Microsoft’s updater. MORE COVERAGE: Windows 10: The first 5 things you need to do immediately after you install it Tech bloggers have been tripping over themselves to sing Windows 10 praise. Whatever the case, it’s finally time for the public to get its hands on Microsoft’s release version of Windows 10.
centipede_shield [macetech documentation] The Centipede Shield is an add-on PCB for standard layout (Uno, Duemilanove, Diecimila) Arduino microcontroller boards. It uses the Wire I2C interface on analog pins 4 and 5 to provide 64 general purpose I/O pins. Any pin can be configured for input or output. The shield uses four Microchip MCP23017 16-pin digital I/O expander chips. Each I/O port corresponds to one MCP23017 IC. The 20-pin 0.1“ headers allow access to 16 I/O, two GND pins, and two COM pins. By default, the power for all chips on the Centipede Shield is drawn from the Arduino 5V bus. If the PWR jumper is shorting the 5V position, then the Centipede Shield will be drawing its power for operation from the Arduino 5V bus. The MCP23017 I2C interface can have up to 8 unique bus addresses. The Centipede Shield uses the official Arduino designation of I2C pins, namely the alternate functions of Analog 4 and 5 on the original Arduino pin configuration. The INTA pads are connected to the MCP23017 interrupt A output pads.
Of drone strikes: “Did we just kill a kid?” Drones are one of those pills that even being somewhat effective, are hard to swallow. PHOTO: REUTERS “Did we just kill a kid?” asked Bryant, a drone sensor operator.“Yes, I guess so!” Brandon Bryant’s recent exposé of drone operations killing hundreds of innocent civilians during his service, which led to his post-traumatic stress and retirement, explains the dark side of the CIA led US drone operations in Afghanistan, Pakistan, Yemen and Somalia. Adding to Bryant’s shock and surprise, his peers believed that they had killed a dog and not a kid that day, and thus it was nothing to worry about. Bryant worked as a drone sensor operator for the USAF from 2006 to 2011, mainly operating from a dark container at a facility in New Mexico. Bryant claims that the operations that he participated in killed more than 1,600 people; the USAF, however, disputes this claim stating that the number killed, in Bryant’s operations alone, are far less. So, are drones good? But then, are they bad?
Libraries Reference Language | Libraries | Comparison | Changes The Arduino environment can be extended through the use of libraries, just like most programming platforms. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data. Standard Libraries EEPROM - reading and writing to "permanent" storage Ethernet - for connecting to the internet using the Arduino Ethernet Shield, Arduino Ethernet Shield 2 and Arduino Leonardo ETH Firmata - for communicating with applications on the computer using a standard serial protocol.

Drone carrying drugs crashes near US-Mexico border 22 January 2015Last updated at 07:18 ET The six-propeller drone crashed in a car park A drone carrying more than six pounds (2.7kg) of methamphetamine has crashed near Mexico's border with the US. Mexican police in Tijuana say they were alerted to an unidentified object in a car park of a shopping centre. "The drone had packages taped to it and was covered with plastic bags containing the drug known as crystal", the local police chief said. Authorities are investigating where the flight originated, who controlled it and where it was bound for. Authorities are investigating who controlled the drone Police say it is not the first time a drone has been used for smuggling drugs across the border. In April, US authorities in South Carolina found a drone outside a prison fence which had been carrying mobile phones, marijuana and tobacco. Other attempts to smuggle drugs have included catapults and ultralight aircraft.
