Rhythm Lamp

Language:	English  • 中文

Objective Speak toward MIC, the lamp will change along with the sound rhythm. 600px principle MIC sensor introduction MIC sensor can turn sound signal to electricity signal. It can detect sound volume but can't detect certain sound. Rhythm Lamp Detect sound volume via MIC sensor and the system will judge which color range the sound belongs to. At the same, comparing with the pre-set trigger value and choosing to open or close light change, therefore, to control color change of the lamp. Equipment Moudle Number Function mCookie-CoreUSB 1 Core board mCookie-Hub 1 Sensor pin board Microduino-Sound 1 Sound detection sensor Microduino-Color led 1 Colored LED light Preparation Setup 1：Connect CoreUSB and PC/Mac with USB cable and open Arduino IDE. Setup 2：Download program:SHENGRI 600px Setup 3：Load code, copy program to IDE. Select the right boardcard and COM port and then download after passing the compiling. Program Description Read sound analog value (A0 pin), which can be defined by users. Then, print analog sound data via serial port monitor. int v=analogRead(A0); Serial.println(v); Detect sound volume every 100ms and distinguish the sound. Soudn range is defined in " zone_vol[3]", which is among 100-600. Users can change that according to personal needs. if(millis()-timer[0]>100) { timer[0]=millis(); if(v>zone_vol[0]) zone=0;//Red else if(v>zone_vol[1]) zone=1;//Green else if(v>zone_vol[2]) zone=2;//Blue else zone=9; } The analog value decides color combination. switch(zone) { case 0: if(color!=0) vol[0]=map(v,0,1023,0,255);//Red else vol[0]=10; break; case 1: if(color!=1) vol[1]=map(v,0,1023,0,255);//Green else vol[1]=10; break; case 2: if(color!=2) vol[2]=map(v,0,1023,0,255);//Blue else vol[2]=10; break; } // Some example procedures showing how to display to the pixels: colorWipe(strip.Color(vol[0],vol[1], vol[2]), 20); Hardware Buildup Setup 1：Connect MIC to A0 pin of Sensorhub and Colored LED to A6. Both sides of Sensorhub have pin description, which can be connected with sensors accordingly. Setup 2：Connect the activated battery box to BM. Setup 3：Stack all modules together without fixed order and finish the circuit buildup. Result Speak towards MIC and you'll find different effect. 600px Video
