Microcontroller Jobs

We are trying to develop a prototype for our idea. We require a skilled worker to help us use the arduino and microphone to consult on our basic design and help us improve it. We would like to pay per hour of consultation. The consultant should ideally be based locally in London and have knowledge of microphones, arduino hardware and circuit design.

Hi, After a PCB design and possible coding for a WS2812B clock. Similar to attached image. Basic Functions - WS2812B leds around clock, 60 for inner circle, 12 for outer circle. - Text on front of clock for the 'hr'. - Buttons on back for reset wifi / set time. - Button battery for holding the time when no power. - Light sensor to 'dim down light at night', and make brighter during the day. Advanced Functions. - Integrated Camera module at centre of clock. Code Integrations - ESP32 WiFiManager (code exists) - ES32 CAM remote viewer (code exists) - Web Based page for modification of lighting. -- Adjust dimming (light sensor) -- WS2812 colour picker wheel for setting, hour, minute, seconds. Thanks Tristan

* This project is built with Micropython on ESP32-PICO-V3-02(compatible with normal ESP32) * It requires to read a value from a pressure sensor (I2C connection) * Tricky is that need to run on ESP32 UltraLowPower processor while the MCU is in sleep mode. IMPORTANT! Please see attached PDF files, I explained the whole requirements and suggestions. Please NOTIFY ME! what MCU and I2C sensor will you use for this project.

Embedded software design and coding for Microcontroller for operation of BLDC motor

I connected a Tuya Zigbee Smart Switch with a Tuya Zigbee(3.0) Wireless Gateway through Smart Life App, and it works perfectly with the app (ON/OFF). I need someone to help me to control the same Tuya Smart Switch with my ESP8266 through the Tuya Zigbee Gateway, without using the Smart Life App. (ESP8266 and Tuya Zigbee Gateway are connected to the same wifi network, so there is no need for internet) So the command should go from my ESP8266, to the router, to Tuya Zigbee gateway to the Smart switch, as shown in the attachment. If you do not have the Tuya hardware, you can connect to my Computer using Anydesk to download to my esp8266, then we can check it if it works with Tuya
