Necesito reparar el código Arduino de dos aparatos que no están funcionando bien: Aparato 1: Báscula Objetivo: Al poner el peso correcto encima, el electroimán debe desactivarse Problema actual: El electroimán se desactiva con el peso incorrecto, y con el peso correcto se abre aleatoriamente, a veces si, a veces no, a veces al rato. Aparato 2: Teclado con música Objetivo: Desactivar la música de fondo del aparato. Problema actual: El aparato funciona bien, pero tiene una música de fondo que no deja de sonar y es muy molesta. La quiero desactivar.

TENGO UN CODIGO ARDUINO EL CUAL LO QUIERO PONER A TRANSMITIR POR BLYNK

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.

Need to get wifi into an outbuilding (namely a static caravan) from the main house on the land which is approx 30-40m away. We already have an ethernet cable running underground which works great, but when we plug in a router or extender it works for a couple of days and then stops, presumably because one router is resetting it's codes or something like that?

I need help with Calculations of AM signals and entropy in Huffman encoding. i will share more details in the chat.

Our goal is to build a bluetooth device which can record calls for our CRM app. Build a device that can do the following 1. Connect to a phone as a Bluetooth headset 2. Has an output 3.5mm for connecting a wired headset 3. Answer calls 4. Record calls 5. Transmit recordings to a mobile App via bluetooth 6. Have a rechargeable battery Device should look like a small square box, with 3.5mm port, usb charging port, two led indicators, on / off switch Device should show two bluetooth channels, one for headset (A2DP) and one for connecting to our app. We will need finished product, which is ready to ship to customers.

Building an arduino controlled lawn mower, I took two 24 volt motors from a jazzy pride wheel chair. welded a frame for my lawnmower with front caster wheels. for the motor controller im using a Cytron mdd10a to Cytron CT-uno with cytron ps2 shield. what I would like to do is be able to control the unit by either joysticks or R1,R2,L1,L2 From my basic understanding with the mdd10a that it would have to be controled via pwm
