Design pcb to house an esp32 module and associated electronics to make distance measurements from 10mm to 140mm. Accuracy within +/-10mm. The ultrasonic sensor needs to be mounted external to pcb via a connector. Do not want ultrasonic modules on pcb, u must design that circuit yourself. The esp32 will be going into deepsleep, so u must shutdown any current that will drain the battery. Pcb must accept battery holder. Deliver the following: pcb, schematic and libraries (kikad or eagle) Manuf gerbers Excelfile with bom (digiket, mouser or RS links)

I made an RGBW led lamp and I want an Android App and a iOS App able to receive udp messages and control the lamp and groups of lamp trhough udp messages. The lamp firmware is based on ESP32. I made a pdf to better explain how the app should be. The images are taken from existing App like Magic Home or Magic Hue. The use should be quite the same... I'm from Italy so we will need to understand how to test the App without having the light.

RFID based Washing machine & Dryer project. This project is regarding controlling a commercial washing machine & dryer using rfid technology. The data of all rfid’s issued will be stored in a database (aws-light sail). When a user swipes the rfid card the terminal, esp32 which is connected to rfid will communicate with webserver & database & will check if the card is present. Depending on the prerequisite conditions, server will send data weather to run the machine or not. If the user has all pre requisites then data base sends communication to run the cycle. Adjacent link can give some idea. When the server sends data to run machines, then two actions are supposed to happen. Action 1: Send a square pulse of certain wave length. (Will be recorded

My project consists in a circuit board which is responsible for communicate with the internet and triggering 4 ele...the circuits of the locks are isolated from the microcontroller circuit to avoid crashes/bugs. The board must have a circuit of lithium battery which must provide an autonomy of at least 8 hours. This circuit will be activated when the site is without power. To connect the ESP32 to the internet, a 4G modem is connected to the board. The board must have a female USB connector to power the 4G modem. The female USB connector must have a circuit capable of having its power interrupted by a command sent by an ESP32 I/O port (After a few hours of initerupted use the 4G modem loses its internet connection and it is necessary to turn it off and on to get it ...
