本帖最后由 bitter 于 2024-9-27 21:48 编辑 【Follow me第二季第1期】任务提交 很高兴能够参加本期由得捷电子和eeworld社区共同举办得本次【Follow me第二季第1期】活动，想想前前后后也参加过好几次follow me活动了，这次应该是第三次了，还是很感谢得捷电子和eeworld社区提供的机会，期待后续活动再能出现一些有意思的板子～ 由于最近比较忙，收到板子后也是拖了比较长的时间直到最后几天才开始相关的活动，时间比较匆忙，完成的不是很好，希望各位审核大大能够手下留情、高抬贵手。 物料清单 我购买物料为活动必备物料开发板、推荐物料舵机、排针，还有一个传感器适配器，还以为是传感器本身，到手一看才发生是一个适配器。   物料展示      项目视频演示 【Follow me第二季第1期】任务提交-【Follow me第二季第1期】任务提交-EEWORLD大学堂 入门任务：开发环境搭建，板载LED点亮 按照Arduino | Adafruit Circuit Playground Express | Adafruit Learning System里的教程一步一步搭建arduino开发环境，并点亮板载LED。 官网下载IDE，https://www.arduino.cc/en/software 安装完成后，打开IDE，点击Tools->Board->Boards Manager，安装Arduino SAMD 安装完成后输入示例代码，使用MicroUSB 线连接开发板，选择对应得端口，点击upload即可烧录程序，观察到如下输出即代表烧录成功。 烧录成功后，重启开发板可以看到开发板上得红灯开始闪烁。 // the setup function runs once when you press reset or power the board void setup() { // initialize digital pin 13 as an output. pinMode(13, OUTPUT); } // the loop function runs over and over again forever void loop() { digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second }  演示图片：   软件流程图：   基础任务一：控制板载炫彩LED，跑马灯点亮和颜色变换 在本次任务中，我们使用到了Mini NeoPixel LED，需要借助Adafruit NeoPixel Library这个库。下载完成后，点击->Sketch->Include Library->Add .ZIP Library…，将对应得库文件导入即可。 #include <Adafruit_NeoPixel.h> #define PIN 8 // 定义按钮引脚 #define BUTTON_COLOR 4 // 调节亮度 Adafruit_NeoPixel strip = Adafruit_NeoPixel(10, PIN, NEO_GRB + NEO_KHZ400); int currentColor = 0; int brightness = 50; void setup() { pinMode(BUTTON_COLOR, INPUT); // 设置按钮 strip.begin(); strip.setBrightness(brightness); strip.show(); } void loop() { // 检查按钮状态 checkButtons(); // 执行当前效果 switch (currentColor) { case 0: colorWipe(strip.Color(255, 0, 0), 50); break; case 1: colorWipe(strip.Color(0, 255, 0), 50); break; case 2: colorWipe(strip.Color(0, 0, 255), 50); break; case 3: colorWipe(strip.Color(0, 0, 0, 255), 50); break; } } bool checkButtons() { bool buttonPressed = false; static int lastButtonState = LOW; int buttonState = digitalRead(BUTTON_COLOR); if (buttonState == HIGH && lastButtonState == LOW) { delay(50); if (buttonState == HIGH && lastButtonState == LOW) { currentColor = (currentColor + 1)%4; buttonPressed = true; } } lastButtonState = buttonState; return buttonPressed; } void colorWipe(uint32_t c, uint8_t wait) { for (uint16_t i = 0; i < strip.numPixels(); i++) { strip.setPixelColor(i, c); strip.show(); if (checkButtons()) return; // 如果按钮被按下，则中断循环 } }   该程序主要是实现了每按一次按钮后，彩色LED在红、绿、蓝和灭四种状态转换。 演示图片：            软件流程图：   基础任务二：监测环境温度和光线，通过板载LED展示舒适程度 在本次任务中，我们除了需要使用上一个任务使用得Mini NeoPixel LED，还额外需要使用温度传感器和光传感器，需要借助Adafruit_CircuitPlayground这个库。安装方式按上一个任务将对应得库文件添加即可。 #include <Adafruit_CircuitPlayground.h> void setup() { CircuitPlayground.begin(); Serial.begin(921600); } void loop() { displayTemperature(); delay(250); displayBrightness(); delay(250); } void displayTemperature() { uint8_t ledCount; float temperature = CircuitPlayground.temperature(); uint32_t color; Serial.println("current temperature is"); Serial.println(temperature); ledCount= (int)temperature/5; color = CircuitPlayground.colorWheel((11-ledCount)*25); for (int i = 0; i < 10; i++) { if (i < ledCount) { CircuitPlayground.setPixelColor(9 - i, color); } else { CircuitPlayground.setPixelColor(9 - i, 0); // 关闭LED } } } void displayBrightness() { uint16_t brightness = CircuitPlayground.lightSensor(); uint8_t overallBrightness = map(brightness, 0, 500, 0, 100); Serial.println("current brightness is"); Serial.println(brightness); CircuitPlayground.setBrightness(overallBrightness); //调整所有灯珠亮度 }   该程序将通过串口实时输出当前的温度和环境亮度。根据当前温度将会实时点亮不同个数的LED并显示不同颜色；根据当前的环境亮度将会调整所有LED的亮度。 演示图片：             软件流程图：     基础任务三：接近检测——设定安全距离并通过板载LED展示，检测到入侵时，发起声音报警 在本次任务中，使用了Mini NeoPixel LED、红外发射器和接收器，还有蜂鸣器。 #include <Adafruit_CircuitPlayground.h> #define SAFE_DISTANCE 450 const int alertTone = 1000; const int irTransmitterPin = 25; const int irReceiverPin = A10; void setup() { CircuitPlayground.begin(); Serial.begin(921600); pinMode(irReceiverPin, INPUT); pinMode(irTransmitterPin, OUTPUT); } void loop() { sendIRPulse(); int distance = analogRead(irReceiverPin); displayDistance(distance); checkForIntrusion(distance); delay(300); } void displayDistance(int distance) { int ledCount = map(distance, 290, SAFE_DISTANCE, 1, 10); uint32_t color; Serial.print("Distance: "); Serial.print(distance); Serial.print(", LED Count: "); Serial.println(ledCount); color = CircuitPlayground.colorWheel((11-ledCount)*25); for (int i = 0; i < 10; i++) { if (i < ledCount) { CircuitPlayground.setPixelColor(i, color); } else { CircuitPlayground.setPixelColor(i, 0); } } } void checkForIntrusion(int distance) { if (distance > SAFE_DISTANCE) { Serial.println("Intrusion detected!"); playAlertTone(); } } void sendIRPulse() { for (int i = 0; i < 32; i++) { digitalWrite(irTransmitterPin, HIGH); delayMicroseconds(13); digitalWrite(irTransmitterPin, LOW); delayMicroseconds(13); } } void playAlertTone() { CircuitPlayground.playTone(alertTone, 1000); }   在靠近的过程中将逐渐点亮不同个数的LED并显示不同颜色，超过安全范围时蜂鸣器将会发出警告。 演示图片：       软件流程图：   进阶任务：制作不倒翁——展示不倒翁运动过程中的不同灯光效果 由于条件有限，没办法制作相应的不倒翁，所以我实际上是用板载陀螺仪检测板子的姿态，然后给出对应的灯光效果：即往哪边倾斜就点亮哪一边的LED，水平则全部点亮。 #include <Adafruit_CircuitPlayground.h> #include <math.h> void setup() { CircuitPlayground.begin(); Serial.begin(921600); } void loop() { float x = CircuitPlayground.motionX(); float y = CircuitPlayground.motionY(); float z = CircuitPlayground.motionZ(); int ledToLight = -1; Serial.print("X: "); Serial.print(x); Serial.print(" - Y: "); Serial.print(y); Serial.print(" - Z: "); Serial.print(z); z -= 9.8; if(abs(x)<2 && abs(y)<2 && abs(z)<2) ledToLight = -1; else if(y<-2 && abs(x)<2) ledToLight = 0; else if(y<-2 && x>2) ledToLight = 1; else if(x>2 && abs(y)<2) ledToLight = 2; else if(x>2 && y>2) ledToLight = 3; else if(y>2 && abs(x)<2) ledToLight = 4; else if(y>2 && x<-2) ledToLight = 6; else if(x<-2 && abs(y)<2) ledToLight = 7; else if(x<-2 && y<-2) ledToLight = 8; uint8_t color= map( ledToLight, 0, 9, 0, 255); if (ledToLight == -1) { for (int i = 0; i < 10; i++) { CircuitPlayground.setPixelColor(i, CircuitPlayground.colorWheel(85)); //水平时都点亮 } } else { for (int i = 0; i < 10; i++) { if (i == ledToLight || (ledToLight == 4 && i == 5) || (ledToLight == 0 && i == 9)) { CircuitPlayground.setPixelColor(i, CircuitPlayground.colorWheel(color));//点亮对应位置的 } else { CircuitPlayground.setPixelColor(i, 0); } } } Serial.print(" - LED To Light: "); Serial.println(ledToLight); delay(100); } 演示图片：                   软件流程图：   创意任务二：章鱼哥——章鱼哥的触角根据环境声音的大小，章鱼哥的触角可舒展或者收缩 由于时间和外部条件的限制，没有制作章鱼模型。本次任务是使用麦克风识别环境音量，根据环境音量的大小点亮不同个数的LED并显示不同颜色。除此之外，根据环境音量的变化逆时针或顺时针旋转舵机。 #include <Adafruit_CircuitPlayground.h> #include <Servo.h> float SoundLevel,lastsoundLevel; // 舵机定义 const int servoPin = A3; // 舵机连接的引脚 Servo myServo; int Speed=90; void setup() { CircuitPlayground.begin(); Serial.begin(921600); myServo.attach(servoPin); myServo.write(Speed); } void loop() { uint32_t color; int ledCount; float soundLevel = CircuitPlayground.mic.soundPressureLevel(10); ledCount = map(soundLevel, 50, 100, 0, 10); color = CircuitPlayground.colorWheel((11-ledCount)*25); Serial.print("Raw Sound Level: "); Serial.println(soundLevel); for (int i = 0; i < 10; i++) { if (i < ledCount) { CircuitPlayground.setPixelColor(i, color); } else { CircuitPlayground.setPixelColor(i, 0); } } if(fabs((lastsoundLevel-soundLevel))>1) { static uint8_t i=0; if(i++ % 2) Speed -= (int)(lastsoundLevel-soundLevel); else Speed += (int)(lastsoundLevel-soundLevel); } else Speed = 90; lastsoundLevel = soundLevel; myServo.write(Speed); Serial.print("Speed:"); Serial.println(Speed); delay(200); } 演示图片：       软件流程图：   项目总结 总的来说，由于时间匆忙，没有很深入的了解这款开发板，但是即使是在有限的条件下也了解了这块板子的多样性和强大功能。第一次使用Arduino，也学会了很多。 最后，感谢得捷电子和eeworld社区提供的机会，期待后续活动！
