Requiero realizar la conexión automática entre dos ESP-01. Funciones deseadas: - Pulsar botón (transmisor-maestro), conexión automática entre el transmisor y el receptor - Mantener conectividad estable al estar cerca (1 o 2 metros) - Enviar a dormir el dispositivo ESP-01 (transmisor-maestro) para ahorro de batería. (siempre deben estar conectados) - Encender un led (receptor-esclavo) cuando se pierda la conexión (solo se debe perder la conexión si los ESP-01 están fuera de rango en metros)
Buenas noches a todos, quisiera hacer un control de asistencia de estudiantes que registre hora de llegada, hora de salida, registro de estudiantes (nombres - curso), capacidad de agregar o quitar estudiantes y registrar sus huellas, que genere un informe que se pueda visualizar en la computadora (sistema operativo windows), mediante wifi, para poder buscar si el estudiante asistio a la unidad educativa, y ver en que dias falto. para el proyecto cuento con: ESP32 dy50 fingerprint sensor arduino uno.
I want an arduin esp32 code where it connects with wifi and sends data over mqtt. It will check the internet connecton, wifi connection and of any failure it would try to re-establish itself. We should not need to reboot the device from outside, it should get back online whenever the problem is solved. The machine may restart after a long time when it is needed ,but remember on any failure it should not keep rebooting.
i am having a relay which communicates with this protocol IEC 61850
The Controller is PIC16F628A, more details will be shared in private chat.
I'm working on IoT project. I'm not very technical. I need help to write a python code to allow raspberry pi to automatically connect two Bluetooth devices to specific serial ports rfcomm0 and rfcomm1. and then I want the python script to automatically start on reboot. would require Video call to show everything in details. I might not be very clear about this so please ask me any questions.
We have few sensors connected to esp32 and we would like to show the values in hdmi monitor via esp32. You need to establish uart, I2c or any other (not mqtt) connection between esp32 and I2c and make them displays le. You don't need to worry about sensors, your project will be only to connect esp32 and raspberry and display via hdmi port
We are looking for an arduino expert to write code for arduinos. Experiance with actuator, servo, stepper motors, various sensors, key pads, LCD screens, batteries, and other electronic components is essential.
Hi, I want to develop 10Msps, 1MHz arbitrary waveform generator. The device should have a PCIe interface to connect to Raspberry CM4's PCIe bus. The following components must be used. CH368, STM32F4 or G4. 10Msps DAC. Deliverable: * Hardware design (EasyEDA, KiCAD, or Altium) * Linux Driver * Demo Python CLI application Timeframe: Until before Dec starts
I have an ESP32 chip with the code attached. The problem is that it works perfectly when pairing it the first time, but when I restart the chromecast v3 or it unpairs or it also happens that it unpairs the remote control from the chromecast having to factory reset it.
Need to know Mplab Programming for PIC16F628A. Compiler is CC5 x compiler. Details will be send by chat.
I'm seeking help setting up a process to upload our programing to an Olimex (Arduino) board using TAG. I have some "TAG" type hardware but I have not been able to connect all the dots. Freelancer must be available during USA business hours.
For this project an Arduino programm is needed which measures the frequency of a speed sensor is measured and forwarded until a certain frequency. For a higher frequency manipulated values must be given to output. Program should be automatically in manipulation mode but should be possible to disable and enable by getting double input high low hig within 2 seconds. pin7 = input enable disable Pin 8 = input sensor Pin3 = Output additional inforamtion and calculations are done and will be provided.
Need to perfectly time the LED lights on a cycle wheel to form an arc irrespective of the RPM of the wheel. we expect you to:- - Design the PCB - Provide circuit diagram - Suggestion on better sensors that can be used to perform this activity
The pcb design that i made has an small error and i need someone to help me figure out the issue. Its a combination of Arduino Nano MCP328P + MCP2515 CANBUS board but in a smaller size with lots of extra arduino nano stuff removed as i will not be needing it. MCP328P chip and FDTI chip do communicate with PC and all digital/analog in/outs work quite well so no issues there, however the MCP2515 part is not able to receive nor send CANBUS messages so i am guessing within this simple pcb design i made an error that i cannot figure what is.
I have a motorized TV lift, i am able to control the lift by nodemcu. But now i want to make this device in production as want to sell this module. And my client will easily connect it with google home and alexa, and control the lift
the system will comprise a raspberry pi zero with 433mhz receiver to receive code hoping remotes. it will also have 4 relays to controll gates etc when the activated by remotes. The system must have a web interface for managing of remotes and assigning it to different users and 1 of the 4 functions The system must also keep a log of remote presses The web must also have a user management system where only admins are allowed to add / manage users, normal users are only assigned remotes
Project based on IOT and PCB designing. Need a IOT engineer who can design me a compact PCB for home automation project it should be successful with all the elements perfectly placed and should give a best outcome. please look the reference videos pcb gerber file - youtube video- ----------------------------------
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.
Need help flashing firmware for rk3399 LCD display
Hi, i have an ESP32 device and i found a library that interface with Alexa, the library is Fauxmo, sometimes it works well, some times it does not work well. I can send my code and hope you can find the bug and fix it soon or help me to find another solution. I have to send commands to Alexa and also use the Alexa app To be sure you read all this requirements , when replay start with "Hi Andrea, ..." Thanks

Hi, I need to get the circuitpython library for my device into the circuitpython community bundle The instructions are here Are you able to do it?
HI, we have existing ESP32 firmware. https://www.amazon.com/gp/product/B08246MCL5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The main tasks are: 1) Drive a stepper motor via TMC2226 - mostly working 2) Monitor a thermo module for overheating, if overheating, stop motor - mostly working 3) SD card module to store data - not implemented 4) MPU6050 to monitor linear movement in one dimension (Y) and use it for automatic start in case of shaking, or stall guard, in case linear motion is blocked, switch of motor - partially working - with bugs 5) 2 fan motors for cooling driven by transistor coupled to a step down/up converter for voltage smoothing and noise reduction. 6) UI via webserver, mostly working for basic and advanced control, OTA firmware update iffy, the file upload dialo...
