Necesito que me desarrolles el diseño completo de una máquina de llenado basada en Arduino para dos tipos de líquidos viscosos: zumo y aceite. El rango de dosificación debe ir de 10 ml a 120 ml y la velocidad de dispensado ha de ser lo bastante alta para trabajar en línea con una cinta transportadora: cada vez que una lata pase, el sistema debe verter la cantidad programada sin detener la cinta. Requisitos clave • Detección de lata: prefiero un sensor inductivo u óptico; acepta sugerencias si logras mayor fiabilidad. • Control de volumen: quiero poder configurarlo por código y, opcionalmente, afinarlo con un potenciómetro frontal. • Compatibilidad de líquidos: las piezas en contacto con zumo y ...

I want to build a small, self-contained charging station that wakes up only when it “sees” a bottle and a can. The core will be an Arduino (any recent 32-bit board is fine) tied to a solar panel and battery pack. A lightweight AI vision module or camera running something like TensorFlow Lite or OpenCV should continuously—or on a duty-cycled basis—look for bottles. The moment a bottle is detected, the system must move straight into the charging routine without waiting for external confirmation; no alerts, no logging, just automatic activation. What I need from you • Complete Arduino firmware that integrates the vision trigger with the charge-controller logic. • A schematic / wiring diagram showing how the camera, solar panel, charge contr...

I’m working on a project using the AVR-IoT Cellular Mini (Sequans Monarch 2 modem) where I customized the Arduino-based firmware myself to periodically send GPS latitude and longitude data to my backend (BE) over HTTPS. The goal is to push GPS data (lat/long + timestamp) to a REST API endpoint within a specific time interval and verify that the data is successfully received and visible on the backend. However, I’m currently blocked by a TLS issue when trying to configure the CA certificate for HTTPS. When I attempt to add the root CA certificate (ISRG Root X1 – Let’s Encrypt) into the device/modem, I receive an error stating: “CA certificate input too long” Because of this: The TLS handshake fails. The HTTPS request does not complete. The end...

...have an ESP32 dev board on my bench and need it turned into a compact sensor hub. The entire focus is sensor integration—specifically motion & proximity plus light & sound. Some of the devices will be hard-wired to GPIO pins while others should connect wirelessly, so the firmware must handle both connection paths seamlessly. Here’s exactly what I need delivered: • Well-commented source code (Arduino-ESP32 or ESP-IDF) that polls each sensor, filters noise, and publishes readings over Serial and MQTT. • A clear wiring / pin-out diagram for the hard-wired sensors. • Configuration notes that let me pair or re-pair any wireless sensor modules. • A short README covering library installs, flash commands, and expected output. Acceptance...

I’m putting together a very small-scale project on an Arduino Uno and simply need a clean, well-commented sketch that switches an LED on and off. No elaborate libraries or peripherals—just straightforward LED control that compiles in the current Arduino IDE and can be uploaded over the standard USB cable. What I expect from you • An .ino file that drives either the onboard LED (pin 13) or an external LED on any digital pin I can redefine at the top of the sketch. • Clear inline comments explaining each step so a beginner can follow the logic and reuse the code in future experiments. • A short read-me noting the exact IDE version you compiled with and the wiring diagram if you choose an external LED. That’s all—simple, reliable, a...

I want a simple two-channel radio link that can do just two things reliably: 1) vary the speed of my brushless DC motor through its ESC (accepts S-Bus or standard PWM) and 2) toggle a single relay on or off. Hardware • I already have the motor, ESC, and relays. • You may choose Arduino, Raspberry Pi, or any Adafruit board—use whichever keeps the build small, inexpensive, and stable. Radio requirements • The handheld transmitter must let me select the operating band with a physical switch: 2.4 GHz, 900 MHz, or 433 MHz. • If LoRa is the cleanest way to hit those bands, great—just make sure the LoRa hop gives me at least a 1 000 ft (≈300 m) clear-line range. Long-range reliability is more important than data rate or extreme power ...

I need someone who can program dwin display, What’s left is the code that brings it to life and links it to an Arduino-based controller here in Thailand. The job covers two tightly-coupled parts: 1. Flashing the DWIN display with my existing pages so that every button, slider, and status field behaves exactly as designed. 2. Writing the Arduino firmware that listens to those commands, drives the motors and other actuators, polls the attached sensors, and feeds live values and alerts back to the screen. All three interface tasks are in scope—motor or actuator control, sensor monitoring, and displaying real-time information and adjustable settings—so the sketch will need a clean, well-documented serial protocol that keeps everything perfectly in sync.

...lets one ESP32 talk to an ESP32-C5 through Firebase. The goal is straightforward: push a small JSON payload from the first board, have it appear on Firebase almost instantly, then pull it down on the second board so it can react (toggle a pin, echo the data, or similar). I will flash both boards myself, so your work ends at well-commented source code and a quick setup guide.

I need a clean, well-commented Arduino sketch for the Pololu 3pi that lets the robot visit six preset locations, interact with the magnet at each spot, and return to its starting line in under four minutes. The only sensing method available is a magnetic sensor array, so all point detection and interaction logic must rely on that hardware. Two run modes have to coexist in the same program and be switchable through a simple flag, jumper, or serial command: • Intermediate – the robot must physically touch the magnet before leaving the point. • Difficult – the robot should recognise the magnetic field, stop just short of contact, and then continue. Between locations, I expect a mix of straight dashes and graceful curves; please handle path planning so th...
