Microduino Mobile Bluetooth Controls RGB Lights

Outline Project：Microduino Mobile Bluetooth Controls the Color of RGB Lights Microduino *Objective：The connection of Microduino BT and Microduino Core by cell phone to have Bluetooth communication and then to control the color of RGB lights. Difficulty：High Time-consuming： Maker：Microduino Studio-YLB Principle Mobile clients can simulate the color of the lights via three progress indicators which send the quantitative values obtained from simulation experiment to Microduino Core via BT. Thus, we can easily control the color of RGB lights by calculating since we get both the simulated values and analogWrite(). In order to have a better control experience, we need to connect pins of RGB lights to that of PMW（3、5、6、11) . Since Microduino BT and Microduino Core adopt soft serial port for communication, we can not connect RGB lights to pins (9,10). Otherwise, data chaos may appear. Bill of Materials Microduino Equipments Modules Number Function Microduino-Core 1 Core module Microduino-FT232R 1 Download program Microduino BT（2.1) 1 Bluetooth communication Other Equipments RGB lights 1 For display USB cable 1 For power supply and program download Small 3D print box 1 For beauty Document Android client： 文件:Microduino RGB.zip Notice：Make sure your BT is 2.1 version since Android client is only suitable for 2.1 BT temporarily Program Test： https://github.com/Microduino/Microduino_Tutorials/commit/46ebefd3f9739ccbede60e72d4463f998a33590f Debugging Step 1：Prepare all equipments 文件:Microduino BT RGB all.jpg 600px Step 2：Make sure your BT serial method. Using soft serial port (9,10) for program test. If you adopt serial port (2,3) And you use Core, please change “SoftwareSerial mySerial(9, 10);”to“SoftwareSerial mySerial(2, 3); ” Or if you use Core+, you need to change “mySerial” of loop to “Serial1”. If you adopt serial port (0,1) You need to change “mySerial” of loop to “Serial1”.and can’t fold BT in the download, or the serial ports will conflict. Step 3：Build a Circuit Overlay modules available Make sure common anode RGB pins The longest pin is positive or the widest one when you look at the RGB light in the head. Here no electric resistance is adopted and the pin will be connected to 3.3V. Players can directly measure the corresponding color of the other three pins through a multimeter or a module. And then connect the pins correspondingly. 文件:Microduino BT RGB ok.jpg 600px Step 4：Download test program and open it. First, make sure your BT serial port, which can refer to step 2. Make sure the RGB lights are of common anode. If not, you need to: Change the solution：The longest pin refers to negative and meanwhile, you need to connect it to GND. Change program: you need to change analogWrite(); eg: To convert “analogWrite(6, 255 - red);”to “analogWrite(6, red);” Step 5：After that, you need to compile program and then download . Step 6：Download Android client-side, decompress, install and open it. Step 7：Search equipments and connect. 文件:Microduino BT RGB BT.jpg 600px Step 8：If the connection goes well, then the lights can be easily controlled by mobile Bluetooth. Otherwise, you have to reconnect. After several times of failed connection, you can either power down and reset the system, or just shut off the client-side and restart. 文件:Microduino BT RGB result1.jpg 600px 文件:Microduino BT RGB result2.jpg 600px Result In virtue of Microduino, you can successfully control RGB lights through cellphone Notice Make sure the serial port of BT Figure out whether the RGB lights are of common anode or common cathode Pay attention to the connection method of RGB lights. If you find errors occur among color progress indicators and their corresponding RGB lights, you can also change pins of “analogWrite();” and make it right.
