Schematics and code to create your own Pomodoro timer on a breadboard using Arduino
Those who follow me on Twitter probably saw pictures and quick videos of my digital Pomodoro timer prototype. I used the case of a regular, mechanical timer and built a little Arduino on a breadboard (like, really barebones using a microcontroller) to fit inside it. This is how it looks like:
- My first VSCode extension and Git repository. This is my version of Pomodoro Technique as extension for VSCode. Hope you like it. Breaks down work into intervals (pomodoros) of 25 minutes separated by short breaks of 5 minutes, 4 pomodoros (sets) are separated by long breaks of 15 minutes.
- Best for: People looking for simple and Open Source Pomodoro timer app. Yet Another Pomodoro App which is a very brilliant implementation of the Pomodoro Technique. In many ways, it's quite similar to Focus 10; simple. A timer that counts down 25 minutes and keeps track of the number of Pomodoro sessions sits on the top right corner.
Trusted Mac download WizTools.org Pomodoro Timer 1.2. Virus-free and 100% clean download. Get WizTools.org Pomodoro Timer alternative downloads. It will also help you psychologically separate Work Time from Break Time, giving you renewed energy at the end of every break. I created WorkBurst for me, but I thought you might want to try it, too. It costs $0.99 and is available now in the Apple App Store. Let me know what you think. Create a timer, share it with your team and get ready for more productive meetings.
This was my first hardware prototype ever and I'm quite proud of it! A big thank you to my awesome husband for helping me whenever I got stuck.
In this first part I will show the schematics to create your own Pomodoro timer using an Arduino Micro on a breadboard. This doesn't require any soldering.
In the second post I'll show how I did the smaller version fitting inside the Pomodoro timer.
Ah, in case you don't know: Pomodoro is a technique created to increase concentration and productivity. Learn more here.
How it works
The timer starts with a blue LED 'static', indicating that nothing started yet – I found this useful for knowing exactly when it is rebooted / powered on. When you click the button, it will start a working phase (25 minutes), where the LED will turn red and keep a 'breathing' effect while it's running. A little 'buzz' happens when you click the button.
When the working phase is done, it will buzz in a different tone and the LED will turn to a static green color. This indicates that it's waiting for your input to change to the rest phase. When you click the button (little buzz again) the rest phase starts, and the LED will change to a 'breathing' effect. When the rest is done, it will buzz again and show the red static LED that indicates a new working phase should start. And so on. 🙂
This is how it looks like on the breadboard:

What you will need
Workburst 1 2 – A Pomodoro Timer Technique
- RGB LED (1x)
- 330 ohm resistors for the LED (3x)
- buzzer (1x)
- push button (1x)
- 10k ohm resistor for button (1x)
Schema

It's quite simple, there are just a few details to pay attention to. As the LED is RGB we need to make sure the right pins are assigned, because they are controlled individually in the code. Sometimes they have a different spec, but usually we have RED – GND – GREEN – BLUE with GND being the longer tail. In my code I'm using pins RED = 11, GREEN = 10, BLUE = 9.

Also, the pins need to be PWM otherwise the 'breathing' effect, that slowly dimmers the LED, won't show. That's why we are using these specific digital pins 9, 10 and 11.
Strata design 3d cx 8 0. And this is how my breadboard version looks like – I used a half-size breadboard so things might look a bit different, but it's the same thing 🙂 Fuel for keynote 1 3 – themes for keynote presentations.
Code
The code basically implements a state machine. The timer phases (WORKING or RESTING) won't start automatically, it needs an input from the user – so the button status is only checked in the loop when the timer is not running.
It's highly based on the Arduino website examples and documentation.
