...together an all-terrain rover that pairs a Raspberry Pi 5 with an Arduino. The Arduino will sit close to the hardware, polling and driving everything from temperature-humidity probes and distance sensors to an IMU (pitch/yaw/roll, altitude, compass), ESC-PWM motor controllers, speed-over-ground tracking and battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor va...

I have an Arduino-based board that is powered from its own DC rail, yet it has to monitor several other DC lines whose grounds are completely separate. Right now I’m simply feeding each line through a voltage divider, and—unsurprisingly—the readings jump around or drift because the grounds are floating. The symptom is clear: inaccurate voltage readings that make the data unusable. What I need is a clean, reliable way to sense those isolated DC voltages without tying the reference points together. Whether that means introducing isolated amplifiers, optocouplers, tiny transformers, or another proven technique is up to you; I’m open to whichever approach gives stable, repeatable results and keeps the measurement side safe for the microcontroller. Here’s ...

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.

...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.

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 ...
