Setup 2：Click Files > Examples > mCookie > _101_BirthdayLight, download program. Or download: Setup 3：Select the right board card and COM port, download program. Program description Function “playNote()”Volume control “colorSet()”Color control “blink()”Judge if the key is pressed Define pin #define PIXEL_PIN A0 //Colored led int key_Pin = 2; //Key int speakerPin = 6; //Buzzer Check switch and see if it is pressed. Use file " key_get(key_Pin, 0)" to detect if the key is pressed. " key_Pin " is the pin that connects with the key, which can be change by users. "0" means triggering once pressing the key. "1" means triggering after you press and loosen the key. Each time the key is detected to be "pressed", the True and False values of " play_pause " will change once. Therefore, you can control the music and light according to the values of "play_pause". void blink() { if (key_get(key_Pin, 0)) //Press the key { delay(200); //Shockproof play_pause = !play_pause; // Status changes one time. } } Light change (Red-green-blue-yellow) “colorSet(strip.Color(R, G,B));” R, G and B are three primary colors. Users can change that according to personal needs. add++; if (add == 5) add = 1; if (add == 1) colorSet(strip.Color(i * 10, 0, 0)); else if (add == 2) colorSet(strip.Color(0, i * 10, 0)); else if (add == 3) colorSet(strip.Color(0, 0, i * 10)); else if (add == 4) colorSet(strip.Color(i * 10, i * 10, 0)); Play music Save fixed notes and change the pitch in program definition. int notes[] = { NOTE_C4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_F4, NOTE_E4, NOTE_C4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_G4, NOTE_F4, NOTE_C4, NOTE_C4, NOTE_C5, NOTE_A4, NOTE_F4, NOTE_E4, NOTE_D4, NOTE_AS4, NOTE_AS4, NOTE_A4, NOTE_F4, NOTE_G4, NOTE_F4 }; Hardware Buildup Setup 1：Connect Buzzer to D6 pin of Sensorhub and Colored LED to A0, crash switch to D4. Setup 2：Connect the activated battery box to BM. Setup 3：Stack all modules together without fixed order and finish the hardware buildup. Setup 4：DIY your LEGO birthday lamp. If modules do not work normally, please try to cut off and power supply and restart it. 600px Result Press crash switch, play birthday song and get lighted. The light will get brighter and brighter. Then press the switch once more, the music and light will be turned off. Video
