Fartlight

thingiverse

This is my brand-new creation:\r\n\r\n**Fartlights!**\r\n\r\nIt shows people at a glance whether a doorlock is locked or unlocked.\r\nIf the lock is engaged, Fartlights switches to red and plays a random farting sound effect.\r\nIn addition, it displays a countdown of how long the door has been locked.\r\n\r\nThis setup holds electronic components securely in place.\r\nTo build one yourself, I've included schematics above for your reference.\r\n\r\n**BOM:**\r\n\r\n- Wemos D1 mini module\r\n- MP3 player module (DFPlayer Mini)\r\n- Doorlock switch\r\n- 4.7kOhm resistor\r\n- 10 kOhm resistor\r\n- MicroSD card\r\n- Speaker\r\n- 4-digit, 7-segment display (i2c interface)\r\n- RGB LED ring (12 LEDs, 5V)\r\n- Perfboard with 2.54mm pitch holes\r\n- AWG crimp tool\r\n- 0.14mm flexible wire\r\n- Pin header\r\n\r\n**Code:**\r\nhttps://github.com/flazer/fartlight\r\n\r\n**Video:**\r\nHere's a video I recorded while building this project (Sorry, German only):\r\nhttps://youtu.be/6wjK-_I-JkU
