Raspberry Pi Solenoid Trigger Script -- 4

@martini002

✴️✴️✴️ THIS IS NOT AN AUTOMATIC RESPONSE ✴️✴️✴️ I can do this for you using gpiod, which is the library we normally use on Raspberry Pi 5 for GPIO handling. The script itself is simple, but I do prefer to leave you with something more complete and practical: a clean Python file, an installer you can run once to prepare the whole system, and everything ready so the Pi starts working without manual setup headaches. I can also add a small local portal so you can later change things like input pin, output pin, trigger lockout, and activation time without editing code. About the solenoid, I need to know the exact model you’re using. If it draws extremely low current, the setup is easier, but if it pulls more than the Pi can safely support, then the correct solution is to switch it through a relay or transistor stage and use a proper 5V supply arrangement for both the Pi and the solenoid. I actively work with Raspberry Pi and electronics, and I already have boards ready for testing and development. I would do this project for 250 USD and deliver it in 2 days maximum. Kind regards Martin

@kareemmaize

Hi there To implement this reliably, the most critical part is handling the GPIO trigger cleanly while ensuring the solenoid activation is controlled and protected. I’ll approach this by using gpiozero for simplicity, with edge detection and a lock mechanism so once triggered, the system ignores further signals during the 5-second cycle. This means I understand how to build stable GPIO-based control systems and avoid common issues like bouncing signals or repeated triggers. My process is simple: Set up input pin with pull-down and rising edge detection Trigger output pin for 5 seconds with lockout logic Provide clear wiring guide (transistor/relay + flyback diode) and setup steps I’m ready to deliver a clean, well-commented Python file you can run immediately on your Pi 5. If this aligns, we can proceed quickly..

Best Raspberry Pi GPIO Automation Expert! ⭐⭐⭐⭐⭐ Hi, The real challenge isn’t just detecting a HIGH signal and triggering a solenoid—it’s ensuring the system responds instantly, operates reliably, and protects the Raspberry Pi from electrical stress. Driving a 5V solenoid from a 3.3V GPIO requires careful handling to avoid noise, false triggers, or potential damage to the board. In projects like this, the hardest part isn’t just writing a script—it’s managing timing accuracy, signal stability, and safe interfacing between low-power GPIO logic and higher-power actuators, all while ensuring consistent behavior without glitches. I would approach this from a hardware and system perspective: implementing clean GPIO signal detection, precise timing control for the 5-second activation, proper debounce logic, and safe switching using a transistor or relay—ensuring reliable operation every time without risking the Raspberry Pi. A couple of questions to clarify before diving in: 1. Do you need a complete wiring reference along with the script? 2. Will the solenoid be powered from a separate supply or shared with the Raspberry Pi system? Feel free to message me—I can guide you through similar implementations and deliver a reliable, ready-to-use solution for your setup. Best regards, Prat PCB Must Innovations

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have previously developed Raspberry Pi scripts to monitor GPIO inputs and control outputs for automation projects that worked seamlessly with precise timing and debouncing. The key to successfully completing your project is ensuring reliable detection of the camera's digital HIGH signal and managing the solenoid activation timing with proper debounce logic. Approach: ⭕ I will use the gpiozero library for its cleaner interface and ease of use. ⭕ I will choose GPIO pins away from I²C and UART by default and clearly define them at the script's top. ⭕ The code will watch the input pin for a HIGH signal, trigger the solenoid output pin energizing it for exactly five seconds, then ignore further input triggers during that period. ⭕ I will include detailed comments and a README header section covering wiring and power considerations, including using a transistor or relay. ⭕ I'll provide all commands to install dependencies and set up GPIO access on the Pi. ❓ ❓ Which GPIO pins would you prefer if any, or do you want me to suggest? ❓ Do you already have the transistor or relay setup for the solenoid power? I am confident I can deliver a reliable, well-documented Python script that meets your requirements promptly. Best regards, Nam

Hi there, I reviewed your requirements and I’m a senior embedded/IoT engineer with 9+ years of experience working with Raspberry Pi GPIO, real-time control, and hardware interfacing. This is a straightforward but timing-critical task—I’ll make it clean, reliable, and safe for the Pi. Approach - Use gpiozero (clean + stable) with edge detection for fast response - Implement non-blocking trigger lockout during the 5s activation window - Add debounce + state guard to prevent false retriggers - Provide safe GPIO defaults (e.g., GPIO17 input, GPIO27 output) avoiding I²C/UART conflicts - Include proper hardware protection notes (transistor + flyback diode for solenoid) Deliverable (single .py file) - Well-commented script with configurable pins - Built-in README (wiring + setup + install commands) - Reliable 5-second activation + ignore retriggers during cycle I ensure robust GPIO behavior and safe hardware interfacing, so it works perfectly on first run. Best regard

@adisonw

Hello! I'm excited to see your project — it aligns with my experience. I’ve worked with Raspberry Pi GPIO control for hardware-triggered actions, including debounce logic, timed outputs, and safe interfacing with external devices like relays and solenoids. This is a clean, well-scoped task that I can implement reliably. I’ll provide a concise Python 3 script using gpiozero for readability and stability. It will monitor a configurable input pin, trigger a 5-second output pulse to control your solenoid, and ignore further signals during that window. I’ll also include clear comments, pin configuration at the top, and safe defaults that avoid I²C and UART conflicts. The script will include a header README explaining wiring, including transistor/relay usage to safely drive the 5V solenoid from the Pi’s 3.3V GPIO. I’ll also provide simple install commands and setup steps so you can run it immediately. Questions: Will your camera output 3.3V logic, or do we need a level shifter or optocoupler for safe input? Do you prefer using a relay module or a transistor-based driver for the solenoid? Hope we can team up and make this project a success! Thank you for considering my proposal.

@soniaer987

This is straightforward GPIO work — I can have the script ready quickly. I'll use gpiozero for clean, readable code. The logic: monitor the input pin for a rising edge from your Sony camera's AI output, fire the solenoid GPIO high for 5 seconds, then ignore further triggers until the cycle completes. Debounce handled natively. I'll pick safe GPIO defaults that stay clear of I²C and UART on the Pi 5, with everything declared at the top for easy swapping. The file header will include a short README covering transistor/relay wiring to safely drive the solenoid from 3.3 V logic. Deliverable: one clean .py file + install commands. Ready to start immediately.

@henryn41

Hi, this looks very clear and thanks for the detailed description. Before I start, just a couple of quick checks: 1. What voltage level does the Sony camera output for HIGH (3.3V or 5V)? 2. Will the solenoid be powered from a separate 5V supply? 3. Do you already have a transistor/relay circuit in place, or would you like me to include a simple wiring diagram? 4. Do you want the script to run continuously on boot (as a service), or will you run it manually? I can deliver a clean, well-documented script with setup instructions once these are confirmed. Henry

@jeremiasg17

Hello! I’ve built a similar system that automates triggers based on GPIO signals, improving responsiveness in real-time applications. I can show you the implementation in chat if you’d like. For your project, I would set up a listener on the GPIO input to detect the HIGH signal from your camera and activate the solenoid for five seconds while ensuring that further triggers are ignored during that time. I recommend using the `gpiozero` library for its simplicity and clarity. What GPIO pins are you considering for the input and output? It might help to know so I can suggest sensible defaults that won't conflict with I²C or UART. If you’re open to it, I can share a similar build and we can explore how it fits your needs. Looking forward to your thoughts!
