DIY Arduino Lamp

cults3d

I built an Arduino decorative lamp.It shines with a pleasant warm light and looks nice in the background. You can turn it on and off by clapping YouTube Video - https://youtu.be/1b6CKg4IGfI Parts Sound Sensor- https://www.banggood.com/3Pcs-Sound-Detection-Sensor-Detection-Module-Electret-Microphone-p-943281.html Arduino Nano- https://pl.aliexpress.com/item/32341832857.html Relay- https://pl.aliexpress.com/item/32649659086.html 230v to 5v step down transformer- I removed it from a small phone charger Light Bulb- You can use any bulb you want. Arduino sketch int Microphone = A0; int Relay = 10; int clap = 0; long detection_range_start = 0; long detection_range = 0; boolean status_lights = false; void setup() { pinMode(Microphone, INPUT); pinMode(Relay, OUTPUT); } void loop() { int status_sensor = digitalRead(Microphone); if (status_sensor == 0) { if (clap == 0) { detection_range_start = detection_range = millis(); clap++; } else if (clap > 0 && millis()-detection_range >= 100) { detection_range = millis(); clap++; } } if (millis()-detection_range_start >= 400) { if (clap == 2) { if (!status_lights) { status_lights = true; digitalWrite(Relay, HIGH); } else if (status_lights) { status_lights = false; digitalWrite(Relay, LOW); } } clap = 0; } }
