1602 LCD 显示
这个浇花系统计划加上LCD显示,比如当前湿度等等
使用Intel Edison以及Grove Starter Kit附带的RGB Backlight LCD来实现这个非常简单
打开:Sketchbook_Starter_Kit_V2.0-master\Grove_RGB_Backlight_LCD
发现里边有各种示例
以下是Hello World的示例

除了显示以外,我们需要读取湿度传感器的数据
这个很简单,就是通过模拟口读回数值进行判断
可以用电位器模拟,代码如下:
// Demo for Grove - Starter Kit V2.0 // Prints the value of the potentiometer to the serial console. // Connect the Grove - Rotary Angle Sensor to the socket marked A0 // Open the Serial Monitor in the Arduino IDE after uploading // Define the pin to which the angle sensor is connected. const int potentiometer = A0; void setup() { // Configure the serial communication line at 9600 baud (bits per second.) Serial.begin(9600); // Configure the angle sensor's pin for input. pinMode(potentiometer, INPUT); } void loop() { // Read the value of the sensor and print it to the serial console. int value = analogRead(potentiometer); Serial.println(value); // Wait 0.1 seconds between readings. delay(100); }
