镭射激光逗猫神器

喵星人对于激光发射器发出的光点有着天生、难以抗拒的执着。它们就像一个个职业杀手一样直接的扑向那个小小的红色激光点。对于猫咪们来说狩猎是一项很好的运动。看着萌宠们发起攻击的样子，作为铲屎官的你会不会觉得是一件饶有兴趣的事情呢！通常你只要拿起你的激光发射器就可以做到，但是你总会预先知道激光点的方向。让我们给这个游戏制造一些混乱元素——可以平面移动或改变仰角的激光炮塔，并让它可以周期性地随机移动。先看看下面的视频~
第一步：准备项目组件清单
它需要用你惯用的任何舵机来配合驱动塔楼。这里有两种方案：
RobotGeek 云台:
如果你喜好添加一个摄像头或者附加一个的自带钓鱼杆的逗猫玩具，这款将是一个好的选择。
RobotGeek云台和舵机
镭射激光发射器和固定配件
Geekduino或者其他兼容Arduino UNO 开发板
传感器模块 (推荐，可简化接线)
7V 5A 电源
Mini 云台：
不错的低成本选择, 但是9G 的舵机输出的力量有限。
Mini 云台套件
9G 舵机 x 2
镭射激光发射器和固定配件
Geekduino或者其他兼容Arduino UNO 开发板
传感器模块 (推荐，可使简化接线)
6V 2A电源
第二步：组装炮塔
如果你使用的是RobotGeek云台，安装说明可以在这找到。
如果你使用的是Mini云台, 安装说明可以在这找到。
拿上激光发射器，让我们把它连接起来。
第三步：接线
设备 | 引脚类型 | 引脚编号 |
平移舵机 | 数字 | 10 |
仰角舵机 | 数字 | 11 |
激光发射器 | 数字 | 2 |
确保设定的输入电压能供更大的伺服7v运行。对于9G的伺服系统，你可以用5V或6V的电源。真的是超级简单的接线。赶紧编码起来吧！
第四步：编程
上传以下代码到你的 Arduino 主板上。

//write initial servo positions to set the servos to 'home' panServo.write(panValue); //sets the pan servo position to the default 'home' value tiltServo.write(tiltValue);//sets the tilt servo position to the default 'home' value
randomSeed(analogRead(0)); //set a basis for the random() engine, based off of analog0 which will be a random number because nothing is attached
digitalWrite(LASER, HIGH); }
void loop() { dazer_pause_roll = random(1, ROLL_MAX); //pick a random number between 1 and ROLL_MAX pause_length = random(PAUSE_MIN, PAUSE_MAX); //pick a random number between PAUSE_MIN and PAUSE_MAX delay(pause_length); //use the random number to pause for pause_length milliseconds
pan_goal = random(PAN_MIN, PAN_MAX); tilt_goal = random(TILT_MIN, TILT_MAX); dazer_speed = random(SPEED_MIN, SPEED_MAX); //perfom the loop while the current positions are different from the goal positions

把你的猫咪萌宠抓过来，开启它吧！（当然是开启你的塔楼啦，而不是你的猫咪啦！）你的萌宠可是自带电源的哦！可不要尝试给你的猫咪充电哦！
第五步：Done！就是这么完美！
现在铲屎的你只需坐下来，看着你的猫咪追逐和攻击那个“邪恶”的小红点啦！
