文件:Microduino Crash-rect.jpg Microduino-Crash Sensor Microduino-Crash Sensor is a sensor which can perceive collision. It is used to detect if there is collision or crash. Therefore, it can also be called crash signal sensor. Due to different collision position, it can classified as left-crash sensor or right-crash sensor. Crash switch can turn mechanical quantity to electricity. When this sensor collided with an object, it'll cause circuit switch close. So, the circuit loop will be opened, the LED will be lighten and the voltage between the two sides of the sensor will turn high level to low. Microduino-Crash judges collision by detecting the electrical level between its two side. It can used in limit and anti-collision such as 3D print motor limit switch and robot anti collision. Features Left-crash and right-crash LED collision indicator Small and easy to install Specification Electrical specification Operation voltage: 5V Input device Tech parameters Pin description: GND, VCC, signal input and NC(Empty). Digit input Size Size of the Switch: 12mm*6mm， Size of the Board: 20mm*20mm 1.27mm-pitch 4Pin interface connected with Sensorhub Connection method Include left-crash and right-crash 文件:Microduino-CRASH Sensor rule1.jpg 600px 文件:Microduino-CRASH Sensor rule2.jpg 600px Document Principle: 文件:Microduino Crash.Zip Development Preparation Make sure you build Microduino development environment. If not, please refer to: Microduino Getting started Choose the core module 1. Adopt Microduino-CoreUSB or mCookie-CoreUSB as the core board. 2.Adopt Microduino-Core or Microduino-Core+ as the core board and you also need Microduino-USBTTL to work with the core for program download. Program Open Arduino IDE, select File→Examples→Basics→DigitalReadSerial program example, select the right board, compile and download. 文件:MCookie-crashCodeExample.JPG 800px int pushButton = 6; Define input pin as D6(Also can be defined by users.) pinMode(pushButton, INPUT); Define pushButton as the input pin. int buttonState = digitalRead(pushButton); Read values of pushButton. Open the serial monitor after download. When there is no collision, the input value is "1" and the input value is "0" under the opposite circumstance. So we can judge if there is collision by input values on the serial monitor. Hardware Buildup Connect Microduino-Crash and the Sensorhub's digital port(D6) which is also the input pin of "pushButton".

Choose the right board and COM port, compile and download. Please refer to: AVR Core：Getting started Open the serial communication after download and you'll see button input values.
