ardReveil v7

Last update: Tue Mar 31 21:48:37 2026

This is a new Template for ardReveil v7 nicknamed Morning Classic 7 because it's for waking up in mornings, classic style (with a twist) and using 7 segments!

Presentation

Principle

Points of interrest

Distance sensor rather than button

Load it with your country days off

No sound but fat vibrations

What MCU to use?

ATtiny2313

If I go Tiny2313, I will do something like that:

1-3 pins free

No ADC so use comparator for sensor to make it digital ("close/far", no distance measurement)

No I2C free (hard on used by ISP programmer) so use logic I2C for RTC

Implementation

Bill of materials

TM1637 to drive the common anode 7 segment

7segment x4 (this one if you care)

RTC DS3231 because no need of the RAM and precise +/- 1 minute per year (and in my collection)

Vibration motor recycled from a PS3 controller
