    ...an encrypted message or hash that only your server can validate. ✅ Solution: Use NTAG 424 DNA for AES-128 encryption & dynamic authentication. ❌ Risk: More expensive than regular NFC tags but extremely secure. 3. Implement Server-Side Authentication (Tokenized URLs) Instead of embedding a static URL on the NFC tag, generate a unique, temporary token for each scan. The URL could look like this: arduino Copy Edit The token is validated server-side and can: Expire after one use (prevents replay attacks). Be tied to the NFC chip UID (ensures it’s the original tag). Include a cryptographic signature (HMAC or JWT) to prevent tampering. ✅ Solution: Use JWT (JSON Web Token) or HMAC signatures to validate scans. ❌ Risk: Requires a server backend to generate

The code is supposed to turn on a small pump and keep it running until a set conductivity threshold (780) is reached in the water. This is part of a larger science fair project focused on Diabetes. Ideal Skills: - Proficient in Arduino programming - Experienced in troubleshooting and correcting code - Knowledgeable about conductivity sensors The task should be relatively quick and straightforward for someone with the right skills and experience. Please reach out if you can help. Thank you!

    ...codebase developed in the Arduino environment. The project involves programming an ESP32 to work with a GPS correction system using NTRIP and communicating with the ZED-F9P module via I2C. Code is ready but we are having some issues, and they must be fixed. - we have the project hardware done, just need to get the code fixed, we can test locally after changes. Project Overview: The system receives GPS correction data via NTRIP using an internet connection through either Wi-Fi or mobile data. These corrections are then transmitted to the ZED-F9P module to enhance GPS accuracy. Currently, the code has issues specifically with mobile data connectivity and the NTRIP connection. Required Skills: ● Advanced experience in C++ programming ● Proficiency with the Arduino ...

    ...dual GC9A01 displays for an advanced animated eyes project using the ESP32-S3 microcontroller. The project involves creating smooth and seamless frame-by-frame animations for a pair of 240x240 pixel displays. The animations will be based on high-quality JPG frames, leveraging libraries such as LVGL, CircuitPython, and TJpg_Decoder. The key objectives include: Synchronization: Both displays need to be perfectly synced for consistent animations across the eyes. Web-based Control: Develop a WiFi-enabled control panel that allows users to connect via a hotspot and select animation modes through a web interface. Animation Modes: Support multiple animation modes, including static and dynamic frames, while optimizing for the ESP32-S3’s storage and performance capabilities...

    Hi, I’m looking for a freelancer to help me design two PCB variants for a stair-lighting controller using a 38-pin ESP32 Dev Module (USB-C). This system will power and control WS2812 LED strips and incorporate multiple sensors for an intelligent lighting setup. Below is an overview of what I need, followed by detailed requirements. At the end, I’ve included links and attachments referencing a similar board and my own sketches. >>> Overview of the Project 1. Goal: Create two PCB variants (Version A and Version B) of a stair-lighting controller for WS2812 LEDs: - Variant A: 2 LED outputs, - Variant B: 16 LED outputs. 2. Board: Uses an ESP32 Dev Module (38-pin, USB-C) mounted on female headers (no extra programming buttons needed). 3. Sensors: 2&tim...
