          Scratch Sensor Board (Picoboard), a sensor interaction board developed specifically for educators and beginners to interact with a variety of sensors, can be used with scratch software , a more lively and interesting animation project with Scratch, is the recommended product for the Steam Education Innovation Forum. With the Scratch programming language, you can easily create simple interactive programs based on the input sensor. The Picoboard integrates a light sensor, sound sensor, button and slider, with 4 additional analog input ports, which can be used to test resistance sensors through a dedicated alligator clamp connection line, and Picoboard is a good way to get into the basics of programming and reading sensors. Scratch is a simple programming tool for teenagers designed and developed by the Massachusetts Institute of Engineering (MIT). MIT has done quite a lot of research and targeted design development for interface preferences. It is not only easy for children to use, but also fun and entertaining, so that children can enjoy their creations. The 2012 was widely popularized in China. Cognitive levels for children over 8 years old can be used to create interactive stories, animations, games, music and art.

Officially provide a complete network learning Exchange community, currently, there are more than 1 million scratch-based projects on the community site sharing, enthusiasts can not only free access to the site, download other people's work, learning other people's program code, but also through the sharing of friends around the world, programming together to create, Together to create an international exchange of learning atmosphere. (1) Install Scratch: Install "Scratchinstaller1.3.1.exe" in the accompanying information (this article explains how to use it in the Windows environment), find the driver in the data and install "Cdm_2_06_00.exe". (2) with the mini USB cable Connection Picoboard and the computer, if the driver is installed correctly, you can open the "Control Panel", and then view "Device Manager", in the Device Manager interface will appear as shown in the virtual serial port number, in My Computer, Give the assigned virtual serial port number when COM1. <ignore_js_op> (3) Open the Scratch software and locate the Sensor button under "Reconnaissance Command", right-click and select "Show Scratchboard Monitor";<ignore_js_op>  (4) can be seen on the interface as shown, the sensor value monitor <ignore_js_op>  (5) on the "Sensor value Monitor" Select "Select serial number or USB interface" and select the corresponding port number, in this case select COM1. <ignore_js_op><ignore_js_op>        (6) After selecting the correct end number, you can see that the "Sensor value Monitor" has a number beating and can slide the slide bar , block the light sensor and speak to the mic, you can see that the number will be beating with your movements, of course, this time also indicates that your sensor board has started to work properly. <ignore_js_op> [size=14.0000pt]1.Case demonstration using the original image of the routine pong, modify the presentation; Modify the script as follows:<ignore_js_op> can not only use the slider to operate the baffle, to achieve the rebound of table tennis;
