Thermo Cup

Language:	English  • 中文

Objective This cup can "sense" water temperature and present different colors according to program settings. Principle Temperature and humidity sensor detects environment temperature and humidity and make light present different color in different sections. Equipment Module Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board mCookie-BM 1 Battery management Microduino-Temp&Hum 1 Temperature and humidity sensor Microduino-Colored LED 1 Colored LED light Other Equipment: Two cells of battery Load the Code Setup 1：Connect CoreUSB and PC/MAC with a USB cable and open Arduino IDE. Setup 2：Click file > Program examples > mCookie >_206_ThermoCup and load the program. Setup 3：Choose the right board and serial port, download program to CoreUSB. Code Debugging Calculate temperature and humidity values--"readByAM2321()" function. You can open serial monitor and check the data. void readByAM2321() { AM2321 am2321; am2321.read(); sensor_tem = am2321.temperature / 10.0; Serial.println(sensor_tem); delay(100); } Define three temperature values and divide the temperature zone into four sections. You can change the values according to personal needs or add more temperature values. #define temp1 28 #define temp2 30 #define temp3 32 Based on the definition for relation between light color and temperature, we set four light RGB values for environment temperature higher than temp1, between temp1 and temp2, between temp2 and temp3 and higher than temp3. You can try to change RGB values or add more temperature sections and see changes. " strip.Color(R,G,B)" R, G and B represents three primiary colors. if (sensor_tem <= temp1) colorSet(strip.Color(0, 255, 0)); else if (sensor_tem > temp1 && sensor_tem <= temp2) colorSet(strip.Color(0, 0, 255)); else if (sensor_tem > temp2 && sensor_tem <= temp3) colorSet(strip.Color(255, 255, 0)); else colorSet(strip.Color(255, 0, 0)); About RGB. RGB value is method of defining light color. R(Red), G(Green) and B(Blue) are the three primary colors, whose values is 0-225. The value represents color intensity. Three different kinds of light can be superimposed together to form a variety of colors, such as (0, 225), that is green. Hardware Buildup Setup 1：Connect the temp.&hum sensor to the IIC pin of Hub and the colored light to A0. Setup 2：Connect the activated battery box with BM module. Setup 3：Stack all modules without fixed order and finish circuit buildup. Result The sensor detects different temperature data. You can also build a beautiful shell with LEGO. Video
