两款有创意的作品

今天在Adafruit上看到两款有创意的产品,特分享给大家:

第一款 - 电路游乐场(Circuit Playground)

先看看下面的这个从视频中的截图:

其主要构成及功能:

10 x mini NeoPixels, each one can display any color

1 x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)

1 x Temperature sensor (thermistor)

1 x Light sensor (phototransistor). Can also act as a color sensor and pulse sensor.

1 x Sound sensor (MEMS microphone)

1 x Mini speaker with class D amplifier (7.5mm magnetic speaker/buzzer)

2 x Push buttons, labeled A and B

1 x Slide switch

Infrared receiver and transmitter - can receive and transmit any remote control codes, as well as send messages between Circuit Playground Expresses. Can also act as a proximity sensor.

8 x alligator-clip friendly input/output pins

Includes I2C, UART, 8 pins that can do analog inputs, multiple PWM output

7 pads can act as capacitive touch inputs and the 1 remaining is a true analog output

Green "ON" LED so you know it's powered

Red "#13" LED for basic blinking

Reset button

ATSAMD21 ARM Cortex M0 Processor, running at 3.3V and 48MHz

2 MB of SPI Flash storage, used primarily with CircuitPython to store code and libraries.

MicroUSB port for programming and debugging

USB port can act like serial port, keyboard, mouse, joystick or MIDI!

第二款 - 加上电能工作的工程尺,下面的图片是从视频中的截图:

两款有创意的作品

ATSAMD21E18 32-bit Cortex M0+ - 256KB Flash, 32 KB RAM, 48 MHz 32 bit processor

Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts.

Can be used with Arduino IDE or CircuitPython

Four capacitive touch pads.

Lots of LEDS - Built in green ON LED, red pin #13 LED, RGB DotStar LED, plus red/yellow/green/blue matching LEDs for each capacitive touch pad

5 GPIO header pins are available and are not shared with USB or the touch pads/LEDs - so you can use them for whatever you like! Digital I/O with pullup/down. 3 ADCs, 1 DAC, 2 PWM, 3 extra captouch sensors

Can drive NeoPixels or DotStars on any pins, with enough memory to drive 8000+ pixels. DMA-NeoPixel support on one pin so you can drive pixels without having to spend any processor time on it.

Native hardware SPI, I2C and Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging). You can have either one SPI device or both I2C and Serial.

Reset switch for starting your project code over

Power with either USB or external output (such as a battery) - it'll automatically switch over

后记,小编朋友研发了一个游戏化的少儿编程在线课程(5-12岁),游戏化教学结合scratch(一款在线少儿编程工具,类似乐高的积木拼搭),我家娃娃学了几次课,非常喜欢(超预期),16次课才200多块钱,对锻炼孩子的思维能力和动手动力很有帮助。
