Abstract

The invention discloses a Scratch development board which comprises a core board and an expansion board. The core board comprises an Atmega32u4 chip, a crystal oscillation module, an analog input interface circuit, an analog output interface circuit, a digital output interface circuit, a download interface circuit and a USB power supply interface circuit. The expansion board comprises a USB interface area, a sensor input area, an expansion interface area, a motor interface area and a core circuit area. The USB interface area comprises one USB interface; the sensor input area includes a slide bar sensor, a light sensor, a sound sensor and a button sensor welded to the expansion board; the expansion interface area comprises four horizontal four-pin fool-proofing interfaces welded to the expansion board; and the motor interface area comprises a four-pin fool-proofing interface under the expansion board. The core circuit area is positioned in the middle of the expansion board, and the core board is connected to the expansion board in an inverted buckling way in the core circuit area. Thus, use is convenient, the appearance is friendly, and the Scratch development board can cooperate with Scratch software to improve the innovation and operation capability of students.

Description

Technical field [0001] The invention relates to a Scratch development board. Background technique [0002] Scratch software is a simple programming tool for teenagers designed and developed by MIT. The Scratch control board can realize the interaction between the virtual scene and the physical scene. It allows users to learn programming language concepts and programming and hardware interaction without knowing it. [0003] However, the Scratch measurement and control board currently on the market is relatively simple, and can only realize the feedback of the values ​​of several sensors, which is difficult to meet the teaching needs. There is also no interface for external expansion modules. Summary of the invention [0004] In order to solve the above-mentioned shortcomings in the prior art, the present invention provides a Scratch development board, which provides an extended interface to connect external sensors and actuators, realizes more functions, and meets modern teaching ...
