Project: Ultrasonic distance monitoring device Description: I've based our first version of it on an ESP8266 MCU. attached to this are; - An 18650 battery - An 100mm diameter solar panel - An HC-SR04 ultrasonic module. - An SD05CRMA MPPT Automatic Solar Charge Controller Board Requirements: - The design does not need USB support - The complete functionalities of the ESP8266 NodeMCU board is to be transferred to the New board - The PCB design should be as small as possible not bigger than 8.5cm diameter (the board can be any shape however) - The components should all be on one PCB with the exception of: ○ The battery which will be attached with wires by an easily detachable header connector. ○ The ultrasonic sensor which will also be plugged in using a simple header. ○ T...
Hi, I am needing the code to connect multiple smart home sensors to a dev board. All I need to be written is the code needed to run a water sensor, vibration sensor, HC-SR501 Infrared Sensor, Sound Sensor, and Two-Way Relay Sensor to a SparkFun ESP8266 Thing Dev Board utilizing the Arduino IDE + ESP8266 Add-on and the Arduino IoT Cloud (for collecting and outputting the data).

I'm attaching the full goal of the final project in the description for context but I only need the code that will connect the sensors and dev board to the Arduino IoT clout and allow them to run. Links to Adruino IDE Add on and IoT Cloud in document. I need someone who can write code for Arduino.
I have a PCB with two MCUs 1. R5F100GEAFB#30 (48LFQFP.) 2. CY8C4014SXI-421 (SOIC 16) PCB is used to control relays based on input received on touch pads. Additionally, an ESP8266 can be connected externally and used to control and sync relay on/off status with the cloud. The functionality will be discussed in detail in a google doc.

I need a simple Arduino code to make an Instagram and Tiktok follower counter. Components initially designed ESP8266 and Led Matrix. I listen to alternative proposals. I need to be able to easily enter the Wi-Fi data, password and Instagram profile ID
There’s some things I didn’t specify in this drawing. The esp8266 has 15 pins on both sides, The lcd adapter has 4 pins to the left and 16 pins at the bottom. Then I’ll need another 16 pin vertical female header for the lcd screen (pin 1 from the adapter would need a trace going to pin 1 on the lcd adapter board, 2 with 2, etc.) As for the components I’ll just need holes so I can solder them. I’ll just need it printed as for which hole is which. [Removed by Freelancer.com Admin]
This project is based on ESP8285 microcontrollers and programming should be done in Visual Studio Code (PlatformIO) Background: This is supposed to be a monitoring system. It involves detecting sensor values at multiple locations (at least 25, with more to be added, on demand). Each sensor location is connected to an ESP8285 wifi board on UART1 (soft serial). All of the 25 individual wifi modules will connect to a central hub - which is another ESP8285 module. This central hub will be connected to a cloud server through a broadband router. It will send the data of all the 25 sensors to the cloud server. The cloud server will also reply back some data which needs to be transmitted back to the 25 sensor modules. Based on this data, the individual 25 sensors will perform some action, like ...
We want a Visual Studio code for our ESP8285 board to do following: 1. Automatically connect to user's WiFi settings (by first starting its own Access Point, then accepting user's SSID/Password) 2. Connect to a hosted server (URL will be shared later) and GET/POST the JSON message. We will share all necessary details. 3. The JSON message to be sent to server should contain: a. The unique Device ID (can be MAC address, or anything unique), b. A user defined name for the device (should be editable) c. A float variable value which is generated within the code This part will be handled later. For now, we just want to see a float value sent as JSON is accepted at the server 4. The JSON message returned from the server will contain two float fields with names: a. M...
The aim of this project is to design and implement a system for wireless communication between a slave / GW ESP8266 device and 20 + masters ESP8266 devices using the ESP-NOW protocol. Each master device will be interfaced with one or two DS18b20 or one or two DHT22 sensors (user selection) , battery voltage indication and RSSI indication.

Have a sketch that use MAX7219 8x8 led matrix, 2 encoders and 4 buttons connected to ESP8266 Wemos D1 mini. All works great. Need to convert this sketch to have it working for ESP32 Devkit (also ESP32-POE). I tried and faced with errors like missing avrpgmspace.h and other errors too. Need help to convert it fast and quick.

Necesito programar el Nodemcu esp8266 Arduino para que envíe a través de wifi las pulsaciones de 2 botones distintos a una base datos instalado en mi Nas Synology. Y otro de botón de reset para poner los contadores de las pulsaciones a 0. Debe de disponer de un pin que cuando llegue corriente indique que el aparato entre encendido. En la base de datos deben figurar Id. Fecha y hora del conteo de los botones, en número de veces pulsados los botones y fecha y hora de encendido y/o apagado, realmente no creo que las conexiones sean así como aparecen en las fotos, por eso necesito un experto

Hi Nevamal P., This is regarding the project that I had posted on Freelancer and discussed with you regarding the use of ESP8266 to create a drinks mixer. It had two NEMA17 motors and I wanted to replace one with a linear actuator/Servo and wanted to get a board made for that too. I was trying to hide my project from further bids but it got deleted. Would you be able to do that and also create a board for me?
Hello, I want to make two weather station based on EPS8266 and LORA sx1278. For this purpose I plan to use this project. 2 ESP8266 and 2 lora sx1278. + 1 ght11 temperature sensor. And maybe one DS3231 to wake up the transmitter to save power. My plan is to mount one lora high above me about 6-7km away in the mountains - that way I will have a direct line of sight with both devices. All the data after receive have to be upload to The Things Network Server
Hello, I need to develop a code for an esp8266 project in which = Read the IR sensor and when active, start the servo motor, when inactive, return to the starting position. (During each status, trigger an LED as well) If the ultrasound is at a distance of 8 cm, it is in a condition to check if the load cell is above 4 kg and if so, activate a led. Check if the weight is still above 4kg after 5 days, if so, activate an LED. Its similiar with this project =

...will operate from the webpage. The default mode will be Auto. If in Manual mode and either Open or Close button has not been activated for 5 mins the ESP8266 will revert to Auto mode with appropriate indication on the Auto button on the webpage. Feedback for the Digital Outputs will be 4 Digital Inputs derived from magnetic Limit switches which will indicate the controlled device has reached its final position, either open or closed. There will be two Digital Inputs for Open position feedback There will be two Digital Inputs for Close position feedback It is envisaged that the two Open/Close limit switches will provide an input to the ESP8266 within 2 seconds, if there is a delay > 2 seconds this will indicate a mechanical fault with the controlled mechanism, an appropr...
