連最簡單的 Analog output 都量不到，檢查
*V,G 有給，焊接沒有短路
- *3.3V/5V 試過，AN 用電錶量都是
- => 難道是電流不夠？
- *Current spec: Operates on 3.0V – 5.5V. The average (and peak) current draw for 3.3V operation is 2.1mA (50mA peak) and 5V operation is 3.4mA (100mA peak) respectively. Peak current is used during sonar pulse transmit
+ *3.3V/5V 試過，AN 都有值，
+ *5V ADC 量到最低值為 20, 距離更近量到的值都很大，5./1024**2C*1000/9.8 =25 inch urrent spec: Operates on 3.0V – 5.5V. The average (and peak) current draw for 3.3V operation is 2.1mA (50mA peak) and 5V operation is 3.4mA (100mA peak) respectively. Peak current is used during sonar pulse transmit
*USB 規範的電壓為5V 最大電流為500mA
*用 Arduino 給電測試，AN 有電壓變異，但是不太跟距離有管連
