Today we start the first of a series of monthly blogposts dedicated to Intel Galileo. Stefano Guglielmetti, who’s already blogged about the Arduino Yún some time ago, shared with us his tutorial about how to get started with the Arduino Certified board.
IMPORTANT: Connect your Intel Galileo to the 5V power supply before any other connection or you will damage the board.
During the Maker Faire Rome, I was lucky to get an Intel Galileo. But when I had to use it, it was suddenly clear that it’s not as straightforward as Arduino. I had to resort to desperate measures and do something that really only a very restricted class of noble people do, I had to read the manual. (more…)
Some days ago RS Components published the 5th and last video in a series of 5 video tutorials about Arduino Robot. After learning how to get started, to remotely control the robot, avoid obstacles and follow lines, you can now learn how to use the TFT screen to deal with images and how to make music and listen to it with the Robot.
In the video below David and Xun show examples and give your tips on how to navigate through these features: (more…)
Once again Xun and David in this fourth video tutorial on the Arduino Robot released by RS Components, are exploring one of the most used techniques in Robotics: following a line, just like factory robots do to get an orientation when they carry objects from one place to another without human intervention.
Watching the video you’ll learn how to create a racing track drawing a black line over a white surface and understand how the different sensors read data that will be used to feed a PD algorithm: (more…)
How does it work? Easily explained:
- User1 sends a tweet with #givejacksweets
• Processing searches for the hashtag, sends a tweet thanking them and passes ‘sweets’ to Arduino
• Arduino activates sweet dispenser for 0.5 seconds
• Photoresistor detects when User2 collects them, and passes to Processing
• Processing takes a photo of User2 and tweets this to the User1
• User1 and User2 both smile
I’ve also cobbled together bits of code from other sources, including: (more…)
This week I’m going to introduce George Koulouris who loves playing, testing, making with others especially at the ‘Petit Fablab de Paris’ where he thinks is a great place to do exactly that! He’s been experimenting with the Arduino Yún focusing on his main interest: the integration of technology to everyday objects. The following post was originally posted on his blog. Read other guest posts on Arduino Yún.
I have two small problems in my house. An ever-increasing electricity consumption bill and a girlfriend which likes to take hot baths at unpredictable times during the day.
Until recently, we left our water heater switched on, 24/7. But then we took a look at our electricity counter readings. Needless to say, we switched it off immediately! An old water heater can indeed make the electricity counter wheel spin fast, very fast…!
So we started switching it on and off whenever we needed to take a bath. The problem was that we weren’t always at home and the water took almost an hour to heat-up! So I decided to connect it to the internet! (more…)
In this third video released by RS Components, Xun and David are going to show you how to deal with ultrasonic range finders, infrared range finders and a trick using ultrabright white LEDs and LDR sensors and in general how to use different technologies to detect obstacles in the way of the Arduino Robot.
In some way ultrasound and infrared operate in the same way: a signal is sent, it bounces on objects and the received echo is used to estimate the distance. With ultrasound, the speed of sound and the time difference between the sent signal and the received one is used, while infrared is more direct as it gives a stronger or weaker reflection depending on how far the signal travels. The estimation of the distance is done via software.
RS Components released the second video focused on the first steps with the Arduino Robot with Massimo Banzi, David Cuartielles and Xun Yang:
In this video you will see where to find code examples on the IDE. The robot library comes with two folders named “learn” and “explore” with examples on how to use the software to program the top board – this is the board you will mainly interact with while the motor board runs its original firmware.
One of the first examples of coding on the Arduino Robot is called “LOGO” which is very similar to an early educational programming language that controlled a virtual turtle moving across the screen with simple instructions. This time however, instead of having a small virtual turtle running on a screen, we have a robot that can respond to commands demonstrating a basic example of movement.
“LOGO” invites users to interact with the robot using the keypad to tell the robot whether to move forwards/backwards or to turn left/right. The program can store a series of commands that will then be executed one at a time. (more…)
Last year, Arduino and RS Components, collaborated in the creation of 10 video tutorials focused on the Arduino Starter Kit. Some months ago they were released in Creative Commons and are available also on our Youtube channel.
During Maker Faire Rome, at the beginning of October, RS Components together with Massimo Banzi and David Cuartielles, unveiled the release of other five exclusive video tutorials introducing the Arduino Robot and exploring various characteristics of this new open-source hardware on wheels.
