Ardublock Graphical Programming for Arduino Starter Kit

 

Arduino open source characteristics which can support of a large number of fans on the Internet,there have been a lot of learning communities. As ArduBlock are the building blocks ofprogramming, largely reducing the threshold of learners do not need specialized knowledge, noengineering background, as long as you like, you can play. Especially now that the great emphasison training the next generation of people, this is for you and your child one of the best ways toparent-child interaction.

Designed for the Arduino a graphical programming software, created by the Shanghai Newcustomer development workshop. ArduBlock official Arduino programming environment softwareis third-party software, must be attached to the Arduino software currently running, the textdistinguishes Arduino programming environment, ArduBlock is the way to build a graphicalprogramming blocks, in such a way makes visualization and programming Interactivity enhancedprogramming threshold is reduced, even without programming experience can also try to Arduinocontroller programming.

Makey Touch Key USB SHIELD Analog Touch Keyboard for Arduino

Many people may have seen the recent Makey Makey analog touch keyboard and video. Video boards can be connected to any electrical conductor by touching the conductor, to give computer keyboard events. To play different games, or effect.
One is through the principle of the single chip microcomputer simulation keyboard, raises a few keys, and use touch form instead of the switch. Now we use a piece of the arduino and Touch the key USB shields, and this effect can be achieve.

Touch key USB shields with Touch as input method, which adopts double contact of the Touch switch, will Touch the client and server-side derivation, connected to two electrodes Touch, Touch two pole, because of the human body resistance, the Touch between the electrodes is, to some extent, current flows through the size can be detected by measuring the current Touch events. Makey's virtual keyboard is also use this method.
