This is a modification of Arduino XMAS Hitcounter and a page crawler was added. By using this project, you can be notified by the bell ring whenever the pledged amount is changed. I hope this is helpful and enjoy!

1. lighter
2. acrylic (roughly 15cmx7cm, thickness:3mm, any shape would work)
3. bell
4. SG90 servo
5. Arduino Uno R3
Bend the acrylic with lighter
1. connect Servo to pin 14 of Arduino
2. attach bell to the servo
3. assemble as long as the servo is free to rotate
A page crawler code is added. You can download the source code at the introduction page. You would have to change the URL to your KS project link.
The main loop of Arduino is to monitor any byte from serial port. If any, ring the bell.
The code is tested with the real world. I hope this help and enjoy.
