+
+LED Bar, common in volume display, is a common sensor component to display analog value. You can use a row of discrete LED lights to make division of this effect, you can also use our element mentioned here. 
+
+For more information, please refer to [Grove_LED_Bar][1]
+
+#Usage
+
+1. To judge certain key if touched
+
+    	unsigned char isTouch(int key)		// key- 0~6, if touched return 1
+
+2. Get touch state
+   
+   	bits 0 to 6 indicate which keys are in detection, if any. Touched keys report as 1, untouched or disabled
+    keys report as 0.
+
+		unsigned char getState()			// will touch state
+
+3. Get Touch Num
+
+		int touchNum();
+
+	if no touched, return -1. or will return the touched key number.
