PIC-Based Pomodoro Timer Project
I’m building a Pomodoro Timer using a PIC18F16Q41 microcontroller. Yes, the PIC18F16Q41 is way overkill for something this simple, but that’s intentional. This design will also serve as a testbed for future projects, like testing sensors and other features I’m planning to use. Plus, I had some PIC18F16Q41 chips left over from a previous project, so why not?
Overview of the Design:
- Power Source: It runs off a micro USB port for convenience.
- Display: A 10-LED bar graph display shows the countdown progress.
- Controls: A single button handles the reset function.
- Programming: I’ve added a POGO header for programming the microcontroller once it’s on the PCB.
Current Progress:
The schematic is done and has been sent off for a few prototypes to be made. I didn’t spend much time on the design since this is the first iteration and more of a test bed to explore the concept. The next step is to integrate the PIC18F16Q41 into my Core MCU Framework and start hashing out the code. For now, this timer won’t use the serial features, but future iterations will take advantage of them.
Why a Pomodoro Timer?
The Pomodoro Timer is more than just a gadget—it’s a practical tool for improving focus and productivity. The Pomodoro Technique breaks tasks into smaller, manageable intervals, usually 25 minutes of focused work, followed by short breaks. This helps you stay on track, avoid burnout, and actually get things done.
For me, it’s not just about making a timer; it’s about seeing how technology can support better habits and productivity. It’s also a good excuse to play around with some ideas and hardware.
How the Pomodoro Technique Works:
- Pick a Task: Decide what you’re working on.
- Set the Timer: Start a 25-minute work session.
- Work Uninterrupted: Stay focused on the task—no distractions.
- Take a Short Break: When the timer’s up, take a 5-minute break.
- Repeat: Start another Pomodoro.
- Take a Longer Break: After four Pomodoros, take a 15–30-minute break to recharge.
It’s simple but effective, and the rhythm of work and breaks keeps your brain fresh and engaged.
Stay tuned as I bring this little project to life. It’s shaping up to be a versatile design, and I’m looking forward to seeing how it evolves, not just as a Pomodoro Timer but as a platform for testing new ideas.
