Arduino Nano与HC-SR04超声波传感器 1. 超声波传感器基本参数 使用电压:DC5V 静态电流:小于2mA 电平输出:高5V 电平输出:底0V 感应角度:不大于15度 探测距离:2cm-450cm 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 const int TrigPin = 2;
使用100nf电容器是可选的,仅用于保持 IC 电源,作为电源,我们使用 12V 2AmpLED驱动器,然后使用稳压器 IC LM7809 将电压降至 9v,并提供给 L139D 的第 8引脚与公共接地。 根据 Arduino、Cc 和 Arduino论坛,Arduino UNO 板支持 7 到 12 伏的输入,但放置 9V Max 更安全。 为超声波悬浮编程Arduino 代码非常...

ArduinoNano R3 × 1个 超声波传感器-HC-SR04(通用) × 5 使用便宜的HC-SR04超声波传感器和Arduino nano,我们可以为机器人构建低成本的传感器阵列。Arduino代码将轮询所有传感器,并通过串行接口发送带有索引和到要处理的Python应用程序的距离的字节数据包。
First we have to define the Trig and Echo pins. In this case they are the pins number 9 and 10 on the Arduino Board and they are named trigPin and echoPin. Then we need a Long variable, named “duration” for the travel time that we will get from the sensor and an integer variable...
This is our circuit with the HC-SR04 ultrasonic sensor and the TCS230 Color Sensor This Lesson will be a bit more involved, and I will take you through it step-by-step. I will need to break things into two parts. In today’s lesson we will cover the Arduino side. We will develop...
We see an Arduino Uno connected to the classic HC-SR04 ultrasonic distance sensor, an LED, and we have to assume a USB battery pack. [Lloyd] recommends the smaller Nano, we might reach for the postage-stamp models and swap the ultrasonic module out forthe much smaller laser time of fligh...
