Description
This is a gadget that connects to your Wi-Fi network and then you can "trigger" it to actuate something with a web browser. I made it to "dong" my bell but you could use it to dong something else, or push something, or pull something... You get the flava!
This is "configurable" in that you can set the position, length, and pause for the stroke through the web interface and the settings will be stored on the device, even after power is removed.
The components required are:
1 HiTec HS-422 Deluxe servo (or similar)
1 WeMos D1 Mini R1
1 WeMos Power Shield (unless you have a better way to power the D1 mini)
The WeMos components typically come as kits so you will need to be able to solder a bit and make tidy wire connections.
WeMos microcontrollers are compatible with the Arduino dev environment, so if you know how to program an Arduino this will be straightforward. You will need to configure your WiFi password in the code before compiling. Once it's running try to reach the device at http://dong2.local . If that doesn't work, look at your router to see what IP address it has and use that instead.
Needs 5-8V DC @ 0.1 A power supply or better. The chip in the WeMos D1 is pretty power hungry when connected to WiFi - not really suited to long term battery operation.
Happy donging!
