Summary of Tea Timer using ATTiny2313 microcontroller
This article addresses the common issue of over-steeping tea due to distraction. The author proposes a solution: an automated system using a motor and winch mounted under kitchen cupboards to remove the tea bag at a pre-programmed time. This project aims to ensure consistent tea taste by controlling steeping duration precisely, utilizing an ATTiny2313 microcontroller for timing logic.
Parts used in the Tea Timer:
- Little motor
- Little winch
- ATTiny2313 microcontroller
- Kitchen sink area mounting space
I usually drink a lot of tea, and sometimes the tea tastes a lot better than average, which means that most times I make tea I fail at least partially.
The taste of the tea depends on a lot of variables:
- The make of the tea. I buy my tea at Simon Levelt and they have approximately 200 different tastes of tea.
- Temperature of the water.
- Amount of tea in relation to the amount of water.
- The way the water is poured over the tea or the tea is put in the water.
- The time the tea is in the water.
- If the water is stirred while the tea is in the water.
- Whether the bitter tea dripping from the tea container is allowed to mix with the rest of the tea.
I always have the problem that if I make my tea I forget to take the tea out of the water at the right time because I’m always distracted by a multitude of things after putting the tea in the water. To take care of this I had a simple to make but effective idea. Above the kitchen sink under the cupboards I mount a little motor with a little winch which takes the tea out of the water after a pre programmed time.

Above the kitchen sink under the cupboards. - What mechanism removes the tea?
A little motor with a little winch takes the tea out of the water. - How is the removal time controlled?
The winch operates after a pre-programmed time set by the microcontroller. - Which microcontroller is used in this project?
The project uses an ATTiny2313 microcontroller. - What variable affects tea taste mentioned in the text?
The time the tea is in the water is a key variable affecting taste. - Can the system handle distractions?
Yes, the automated system works regardless of distractions after putting the tea in. - Is the project considered simple to make?
Yes, the author describes the idea as simple to make but effective.
