A dedicated PCB will drive a self-service car-wash “vendo” unit built around an Arduino Nano. The board must accept the pulse output from a standard electronic coin slot, translate each valid coin into the required runtime, and use that signal to energise five independent relays that handle pumps, valves, or lights. All relays share a common 12 V source, yet the Nano and logic lines stay safely at 5 V, so on-board regulation (12 V → 5 V buck or linear, as you judge appropriate) is part of the layout. The relays themselves need fly-back protection, status LEDs, screw-terminal or JST headers for easy field wiring, and clear silkscreen labelling. A USB-B or tag-connect footprint for in-circuit programming is also required. Deliverables • Complete schematic...

I already have a partially-working prototype for an industrial counter + timer built around an Arduino. It needs to count production units while tracking elapsed time in parallel, show both values on an LCD screen, and push the data over Wi-Fi to my factory LAN. Where I’m at • Core hardware is assembled and a rough sketch is running, but the logic occasionally drifts and the Wi-Fi payloads are not stable. • The prototype can be shipped to you immediately, fully labelled and with a wiring diagram of the current build. What I need from you 1. Clean, well-commented Arduino code that reliably performs the simultaneous counting and timing functions. 2. Solid LCD interface: clear, easy-to-read formatting of count, timer, and simple status icons. 3. Robus...

...that lets me roll a ball across any flat surface and have it actively steer itself so the pen mounted inside draws in the exact direction I choose. An optical-flow sensor will read surface motion, my code will translate that into heading commands, and two small motors inside the ball will supply the corrective spin. The overall sketch is already under way, but I need a specialist who knows Arduino-style hardware and, more importantly, how to marry miniature motors with an ESP32-C module for precise directional control of the ball. Your main focus will be advising on the right motor format, driver circuitry, power budgeting, and the physical/electrical integration so the firmware can call simple functions like setHeading() or setVelocity(). I’m comfortable writing and ite...

If you have prior experience with radiation detect...

...driven by an Arduino. Each of the sixteen micro-switch inputs will correspond to one—and only one—relay output. When a switch is pressed the matching relay should energise for a fixed pulse of 2-3 seconds, then drop out automatically; there is no need for the user to alter that timing. Here is what I need from you: • Clean, well-commented Arduino sketch that reads the 16 discrete inputs, debounces the switches, and fires the appropriate relay for the required duration. • Pin-mapping and a simple wiring diagram so I can connect everything without guesswork (I will be using a common 16-relay module that accepts active-LOW signals, but please keep the code flexible enough to invert logic if needed). • Guidance on any libraries you choose to u...

...ESP32-based prototype uses the MSME INNP441 digital mic, and during live audio streaming it introduces jitter and a screeching interference noise—even though the board sits in a quiet lab. I have already updated the firmware, swapped in fresh hardware, and tweaked every software register I could reach, yet the distortion persists. I’m looking for someone who can dive into the existing C/C++ (Arduino-style) code, analyse the I²S configuration and clocking, and track down whatever is corrupting the audio path. If a schematic or logic-analyser trace is helpful, I can supply both. Any fix should leave us with clean, stable voice capture that we can push straight to our streaming stack. Because this is part of our in-house tech, I will provide the full repository ...

I want to create a branded control board that keeps the familiar Arduino UNO R3 footprint yet swaps the ATmega328P for an ESP32. The finished board must: • expose the usual analog inputs, PWM outputs, serial ports and full digital I/O • break-out every pin through sturdy screw terminals instead of header pins • carry an on-board battery cradle for two 18650 cells (3.7 V each) and an integrated 2-cell BMS • arrive pre-flashed so it shows up in the Arduino IDE exactly like a normal UNO-style target Because the unit will be wall-mounted, an ABS enclosure that matches the board outline, standoffs and connector layout is part of the job. I need mechanical files (STEP/STL) alongside the electronics deliverables. Deliverables 1. Schematic, PCB layout and Gerb...

I’ve set up an Arduino with a Shield Host 2.0 so it can sit between my gaming mouse and PC, but I’m stuck getting a “0-recoil” macro loaded and running. The sketch I already have compensates for both vertical and horizontal kick, yet I can’t work out the right libraries, pin definitions, or upload steps to make it behave as a true USB host device. Here’s what I need from you: • Review the script I’ll send, adapt or refactor it so it compiles cleanly for the Shield Host 2.0 and recognises my mouse. • Map the recoil toggle to one of the spare mouse buttons (or a simple hotkey) and make sure it turns on-and-off reliably. • Suggest whether a fixed or easily tweakable version makes more sense; I’m happy to take your adv...

I have an existing Arduino sketch that communicates on Wifi, controls a pump relay and various other similar functions. The project is designed around the M5Stack CoreS3-SE, with a DIN base to provide connector functionality. I now want the whole project running cleanly in PlatformIO. Your task is to take my current codebase, create a PlatformIO project around it, resolve every library and board dependency, and make sure it compiles without warnings. All third-party libraries must be pulled in through so the project is completely self-contained - no manual installs on my side. Because I need this ASAP, I’m looking for someone who has already done a few migrations and can spot typical pitfalls. Once finished, I should be able to clone the repo, hit “Build” in VS ...
