Todoist task tracker using Node MCU and IFTTT

Another weekend project. This shows me the number of tasks I’ve pending to complete in a day. This should help me reach #TodoistZero quicker everyday. I soldered the resistors and the sevensegment display directly onto the Node MCU Amica ( just for the sake of making it compact…it does look messy though).

I took inspiration from the following posts: https://www.instructables.com/id/Internet-Connected-Remembrall/ https://www.instructables.com/id/Task-the-Ambient-Planner/

This is quite an easy thing to try out and you’ll be up and running in less than 2 hours. This uses the Adafruit IO and IFTTT service to fetch data from todoist. The details of setting it up are covered well in the second link posted above. The code found in that post is outdated and “PROGMEM” cannot be used like that. I’ve updated the code accordingly.
