I need two simple (!) Arduino C++ sketches; the first sketch is for an Arduino Mini Pro (Atmega 328P, 8 MHz, 3.3 V) connected to a Lora Hope RFM95W radio module (915 MHz) and with 3-wire capacitative water sensor connected to the Mini Pro A0 pin (+Vcc 3.3 V + GND). The sketch for the Mini Pro must sense once each day (to save battery) the presence of water at the connected water sensor and then se...

Build IOT device to monitor temperature and position. For the first prototype, use comercial board (like Arduino, Linkit One, ESP, etc) with - DS18B20 temperature sensor - GPS - GSM/3G to send data - WiFi (optional) - Battery Data will be send to our server, we could discuss best way and the periodic to send it (better battery life versus accuracy)

把teensy2.0作为midi设备，从teensy2.0接出八个旋钮或推子控制音乐软件音量，有两个teensy2.0，一个发送，一个接收，也就是一个teensy2.0插在电脑上，另一个teensy2.0(接8个音量旋钮或者推子)通过无线(xbee)发送到这个teensy2.0(作为midi设备插在PC上)。 因此我想请大神帮我写这两个teensy2.0的代码，一个是发送代码一个是接收代码。 下面有一个文件是别人做好的代码，但是只能控制一个旋钮或推子(如果按照这个事例修改为控制八个旋钮或推子的话，就会互相干扰)的音量，我要的是八个。仅作参考
