The battery source(s) is an 18650 shield which provides both 3.3V and 5V. Since the original birthdaycard comes with 3 LR1130 batteries for a total of 3.6V we need two dropper diodes which both drop about 0.7V. The 4K7Ω resistor limits the current. The 47KΩ and 18KΩ voltage divider ensure we get 0 to ~3.3V on pin A0 which we can then use to read the voltage and even report it back to home.\n\n## BOM\n\n- 1x [18650 shield](https://www.aliexpress.com/item/4001251319520.html)\n- 1x [Wemos D1](https://www.aliexpress.com/item/1005001344360716.html)\n- 1x [Never-Ending Birthday Card](https://www.coolgift.com/nl/Never-Ending-Birthday-Card)\n- 2x 1N4001 diode\n- 1x 2N2222 NPN BJT\n- 1x 4K7Ω resistor\n- 1x 47KΩ resistor\n- 1x 18KΩ resistor","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobthree%2Fhappybdayprank","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frobthree%2Fhappybdayprank","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobthree%2Fhappybdayprank/lists"}
