I'm looking for someone with experience in coding Arduino C to create a stepper motor that can sense short-distance movements and have a speed controller. With this project, I hope to be able to utilize the stepper motor with sensors to detect short-distance movements and adjust speed according to my desired conditions. The project should also be built with a reliable source of power and various safety measures should be included as well. It should be controlled thru LCD display. Start and stop switches, start time switch (relays) - after pressing start, it will create motion and after example 5 seconds, it will move back. We can use stepper motors or air pistons. Both will work. If you have experience creating such a device and can show me your work portfolio, I'd like to...
I need integrate bluetooth comunication into flutterflow code.
I'm looking to have an ESP32 webserver developed in Arduino IDE, operating in STA mode (AP is my router) to store data either in a local database (WAMP server, localhost, mySQL) or a Firebase (google) database. Some ESP32 senders, in STA mode as well, send their data to a single ESP32 receiver via ESP-Now protocol. Each sender will have 2 momentary buttons, let's say A and B. The ESP32 receiver acts as a webserver, so it hosts a webpage. On that webpage, there are some squares (simple square areas, divs in css or whatever). Each square corresponds to one sender. When u press momentarily the A button of a sender, this square becomes green. If u press A again nothing happens. If you press momentarily the B switch, then the green square becomes red. If you press again B, no...

Hi Miguel Angel L., I noticed your profile and would like to offer you my project. We can discuss any details over chat.
Description of the code: The code defines a set of pins that control LEDs and switches connected to an ATmega2560 microcontroller. The LEDs can be turned on and off using the defined pins, and the switches can be used to trigger interrupts that change the state of the LEDs. The code is written in C++ and is intended to be compiled and uploaded to the microcontroller using an appropriate IDE and hardware programmer. Problem: The interrupts defined in the code are not working as expected. It is unclear whether the pins defined for the switches are compatible with interrupts on the ATmega2560 microcontroller. Additionally, there may be issues with the way the interrupts are configured and handled in the code. To resolve the issue, a developer with experience in microcontroller programming a...

I am building a wave buoy with Arduino Uno, Adafruit 9DOF IMU, Arduino Ethernet Shield and a 4G router. I am looking for a code that can accurately detect wave activity using the Adafruit 9DOF IMU sensor and output the results to the cloud platform. There are a few ways to accomplish this, but the one I understood the best was to use a combination of signal processing and data analysis techniques. First using the accelerometer and gyroscope readings from the IMU sensor to calculate the orientation of the device ( not sure whether only using the Z axis/ Heave, or combining pitch and roll ). We can then use the orientation data to detect peaks and troughs in the wave activity based on some threshold values... values that can be amended. Once we have detected the peaks and tro...
