Ultrasonic Ranging Module HC-SR05: This is a similar module to the HC-SR04 with minor differences, it has a wider detection range of up to 4.5 meters and a higher accuracy. HC-SR04 Ultrasonic Sensor interface with Arduino HC-SR04 Ultrasonic Sensor interface with Arduino HC-SR04 Ultrasonic Sens...
1.Arduino版 2.超声波传感器 – HC-SR04 3.舵机 – SG90 4.面包板 5.杜邦线 设备制作 首先,制作一个纸板固定超声波传感器,并且使其固定在舵机上。我将纸板建成长方形,在其『长』的黄金分割处的左右各剪一刀,每刀应为『宽』的1/5。然后将两边折起,并用胶水黏住。再将其对准舵机叶片,钻上一洞,使其稳定...
We will first look at an example that does not use an Arduino library. Next, I will show you how you can use the NewPing library to create a more compact code.Cheap ultrasonic distance/proximity sensors are great but in some projects, you might need a waterproof sensor like the JSN-SR04...
