I have an Esp8266 D1 Mini Wemos Wifi Module card and a SSD1306 oled display module for wemos d1 mini 0.66" inches 64x48 I have a ticker to display the Bitcoin price on this screen that works very well by collecting the value from the Coindesk API (but only limited to Bitcoin. The internet connection is made through Wifi defined in the source code, that is, whenever a network changes I have to load the updated code on ESP8266 Changes I want: 1) Inform the Wifi data by cell phone through a screen connected to Esp8266 instead of defining the username and password by the source code. 2) On the same cell phone screen, select which currencies should appear on the ESP8266 screen: Bitcoin, Ethereum, Doge, EOS, Tron, Litecoin, BNB, Cardano, Solana, Monero e Stelar (to get these values y...

Required a c code developer for STM 32 microcontroller with GSM/GPRS module , TO operate three phase induction motor, for more information we will discuss in chat box
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
Hello, I need to design a software that can program an STM32 microcontroller using function block diagram (similar to a PLC) and is capable of storing data on a cloud platform. The device will have 4G module/ Ethernet module to upload data.
Summary: Off the shelf micro based control unit using Arduino, etc. Unit takes 2 pulse inputs and interprets to speed, these are 5 volt PNP inputs. Unit has multiple relay outputs for alarms, 4-20 ma analog output, serial output (fixed length ASCII), Ethernet Modbus and Profibus interfaces (slave). The unit has no keypad nor display, programming wil be via bluetooth running an app on IPhone and Android devices. App writing is required. Unit has 2 modes of operation. Stand alone single pulse processing and differential detecting from 2 pulse inputs. Thru Hole and SMT, coding, testing and all drawings and source code.
Требуется С, С++ разработчик для написания программного обеспечения модуля управления и телеметрии на базе микроконтроллера ESP32 или STM32. 1. Устройство должно подключится к торговому аппарату по протоколу MDB версии 4.2 в режиме SLAVE, и представляться как считыватель банковских карт. 2. Устройство должно подключится к банковскому платежному терминалу по протоколу MDB версии 4.2 в режиме MASTER, и представляться как торговый аппарат. 3. Пример работы устройства: - торговый аппарат делает запрос на оплату на устройство - устройство в зависимости от бизнес-логики делает запрос на оплату на платежный терминал или же сразу отвечает торговому аппарату отказом. -если был запрос на оплату на терминал устройство дожидается ответа и в зависимости от бизнес логики отвечает тор...
C, C++ developer required to write control and telemetry software based on ESP32 or STM32 microcontroller. 1. The device must connect to the vending machine using the MDB version 4.2 protocol in SLAVE mode and present itself as a bank card reader. 2. The device must connect to the bank payment terminal using the MDB version 4.2 protocol in the MASTER mode, and present itself as a vending machine. 3. An example of the operation of the device: - the vending machine makes a payment request to the device - the device, depending on the business logic, makes a request for payment to the payment terminal or immediately responds to the vending machine with a refusal. - if there was a request for payment to the terminal, the device waits for a response and, depending on the business ...
Hello, we had to change our original project, so now we are going to order something a little different. We need a PCB so that it can control an electropump, a solenoid, a safety float and, in addition, it has a safety system to prevent the opening of the box that contains the pcb, that is, if someone opens the box, I want Let me know via wifi or via Lte. It doesn't matter what everything is developed with, it can be arduino or whatever.

Hi, I am looking to align with a strategic partner who can develop a BLE device with the following requirements: - Powered by batteries (>12months service life) - Transmits: "name of the device" and a "magnetic field reading in the z-axis" - Advertising interval can be up to every 2 seconds Further context: - Frequency of reading by central device (Smartphone): once per day --> once per week - Beacon cannot be physically interacted with - The data transmitted will need to be post-processed by a mobile application - Magnetic field reading will change slowly over time (3-12 month period) - Up to 50 units to be within range of the central device at any one time - need to ID exact BLE device - Intent is to produce the beacon/sensor at scale If you believe ...
I need a simple audio hardware design/schematic to manage 8 zones of already wired left/right speakers in my home and two out by the pool. I think I would like a page on my iPad and iPhone which gives me all options of what music I wish to stream, (only one stream for all 8 zones at a time). Off/on for each zone, and volume. Do I simply need an app, a good amplifier, solid wifi connection, smart speaker selector…? No problem if this isn’t the type work you do. Thanks just the same, Steve

Need a STSPIN250 motor driver with current control via PWM. A D.C motor's torque needs to be controlled via regulating the current limit using the STSPIN250 motor driver. Your task is to make a PCB including the STSPIN250 motor driver. It should have two output terminals for D.C motor connection and two input terminal for sending a PWM signal from a MCU to the motor driver for regulating the motor current in real time. There should also be power terminal connector to power the motor driver and the motor. Please refer the below link for the motor driver:
