Doorbell 4.0
Updated: 2022-10-28
Summary
- ESP32 Based (sketch for arduino ide)
- DY-SV8F MP3 board for chimes and sound effects, it has 8MB? of storage built in (manual).
- ESP32: GPIO23 - INPUT triggers doorbell, GPIO17 - TX, connect to RX on MP3 Board
Features
- It's possible to make OTA firmware updates on the ESP32
- ESP32 broadcasts the doorbell ring to the network and a Discord webhook in #doorbell
- You can trigger various sound effects (try sending the doorbell MOO\n, BAAH\n, TRASH\n, PLAY some_number\n as UDP packets)
- Customizable chime (connect USB micro to MP3 board, replace 00001.mp3 with your chime).
Quirks
You can send a UDP packet to the device `PLAY 2` for example would play file #2 on the device. The file system does not always order things as you expect. This dedicated library gives a good overview of the issue and possible mitigations. Absolute worst case you can send UDP packets, iterate through files, playing them, make note of the appropriate file and update the ESP firmware if needed!
Doorbell 3.0
Unknown
Doorbell 2.0
Arduino-based, includes lights and a customizable tone.
To do
* mount in a stable enclosure * move transistor (sound) from pin 12 to another pin so we can use ethernet. (4,10,11,12,13 are used by ethernet/sd card. 5 is buzzer signal, 7 is LEDs) * run an ethernet cable to the doorbell * Improve and expand doorbell code!
Troubleshooting
* Check that the speaker is connected to the green terminals of the arduino, and an audio cable is plugged into the intercom box by the top door. * Hit the reset key on the Arduino * Ring the door bell. Does it work? * Re-upload or modify the Arduino sketch
If this fails you can revert to doorbell 1.0.
Want to improve the doorbell? Change the chime? Here is arduino code. Hack it!
You'll need a USB mini cable to connect. The board is a [1], but choose Uno in the Arduino IDE.
Improvements & ability to alter light and sound patterns via ethernet will be coming soon.
Doorbell 1.0
Via original intercom box.
Fallback instructions.
Go to the intercom box by the top door:
* Ensure the buzzer switch on the top is set to 'On' * Unplug the audio cable from the side of the intercom box by the door.
Doorbell 1.0 functionality should work
Pacific Electronics 3403 Door buzzer system.
