Bluetooth Lamp

Language:	English  • 中文

Purpose Use a phone and Microduino-BT to communicate with Microduino-CoreUSB to control the color of a lamp. Principle Equipment Module Number Function Microduino-CoreUSB 1 Core board Microduino-Sensorhub 1 Sensor pinboard Microduino-BT 1 Bluetooth module Microduino-Lantern 1 colored light Microduino-BM 1 Battery management Document Android Client: Caution: The new BT 4.0 version can only be supported by Android 4.3 and higher. Here we offer Android App. APP download：'File:Microduino-LAMP-APP.zip Hardware Buildup Setup 1：Stack CoreUSB, BT and Sensorhub. File:CoreUSB Ble Sensorhub.jpg 600px Setup 2：Connect the lantern to the A0 pin of Sensorhub. File:Mic colorled ble.jpg 600px Software Debugging Setup 1：Build IDE, connect CoreUSB to your PC and download program code. ble_color_led Setup 2：Download Android Client, decompress, install and open it. Make sure that is operated with Bluetooth open. Setup 3：Click SCAN on top right, name it Microduino and click connection. Setup 4：It appears Serial Present on top right during initializing and then turn to Serial Ready, meaning normal communication. APP description: If you have multiple colored lights, you can switch to Multi Colore mode. The maximum is six. Control the brightness through the circular ring. Switch to turn on or off through the bottom button. Code description: One part for receiving Bluetooth information and the other for controlling color combination of the light via analog value. Reading Bluetooth information The use of BT serial port is baseed on the selection of serial jumper on the board. The default serial port is 0：Serial. #define my_Serial Serial void ble() { while (my_Serial.available()) { char c = my_Serial.read(); delay(2); if (c == 'C') buffer_sta = true; if (c == '\n') { color_en = true; safe_ms = millis(); } if (buffer_sta) { buffer[buffer_num] = c; buffer_num++; } // Serial.println(c); //Serial.println(color_en); } if (buffer_sta) { buffer_sta = false; sscanf((char *)strstr((char *)buffer, "C:"), "C:%d,%d,%d,%d", &sta[0], &sta[1], &sta[2], &sta[3]); for (int a = 0; a < buffer_num; a++) buffer[a] = NULL; buffer_num = 0; for (int i = 0; i < 4; i++) { Serial.print(sta[i]); Serial.print(","); } Serial.println(" "); if (-1 == sta[3]) { colorSet(strip.Color(sta[0], sta[1], sta[2])); } else if ((0 <= sta[3]) && (sta[3] < PIXEL_COUNT)) { colorSet(strip.Color(sta[0], sta[1], sta[2]), sta[3]); } } if (millis() - safe_ms > 3000) { safe_ms = millis(); color_en = false; } } Color change of the light. When there is Bluetooth connection, the color is: if (-1 == sta[3]) { colorSet(strip.Color(sta[0], sta[1], sta[2])); } else if ((0 <= sta[3]) && (sta[3] < PIXEL_COUNT)) { colorSet(strip.Color(sta[0], sta[1], sta[2]), sta[3]); } Otherwise, it will control color automatically. if (!color_en) { rainbowCycle(10, 255, 0, 0, 0); rainbowCycle(10, 255, 0, 0, 1); rainbowCycle(10, 0, 255, 0, 0); rainbowCycle(10, 0, 255, 0, 1); rainbowCycle(10, 0, 0, 255, 0); rainbowCycle(10, 0, 0, 255, 1); rainbowCycle(10, 255, 0, 225, 0); rainbowCycle(10, 255, 0, 225, 1); rainbowCycle(10, 247, 139, 5, 0); rainbowCycle(10, 247, 139, 5, 1); rainbowCycle(10, 255, 255, 0, 0); rainbowCycle(10, 255, 255, 0, 1); rainbowCycle(10, 0, 255, 255, 0); rainbowCycle(10, 0, 255, 255, 1); for (int i = 0; i < 3; i++) rainbow(30); } Result By Microduino, you can control colored lights through your phone and get any color you want. (You can build a beautiful frame with LEGO. ) Video
