Pomodoro timer with ToF sensor in CircuitPython #CircuitPython #Feather #Adafruit @Adafruit @rareblog
Over on RAREblog is a fun Pomodoro timer using an Adafruit Feather M0 and a VL53L0X Time of Flight sensor.
Like many of my friends I use Pomodoro time management when I’m writing or coding. The Pomodoro technique uses a timer to you to get up and take a five minute break after 25 minutes at the keyboard. This helps you focus during the 25 minutes of work and the break keeps you healthy and fresh. The original Italian creator used a kitchen timer shaped like a tomato – hence the name.
A while ago I came up with the idea of automating the Pomodoro.
Recently Richard Kirby started experimenting with an inexpensive VL53L0X Time of Flight sensor which measures distance quickly and accurately. Richard runs the Raspberry Pint MeetUp in London, and you can see his project (and many others) on the MeetUp’s Facebook page.
I thought I’d try and see if I could detect my presence at my keyboard using the sensor.
My Adafruit sensor arrived a few days ago and I wired it up to an Adafruit Feather M0 Express I had in my parts box. I used the VL53L0X demonstration code in the Adafruit tutorial and it worked well.
I’ve been writing the CircuitPython software using Nicholas Tollervey’s Mu editor. This supports Adafruit boards as well as the micro:bit and it’s very easy to install on Windows, Linux and OS/X.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
