This project is a timer for scrum daily standups. Based on team size and needs the timer can be configured from 1 to 99 seconds. The current time left is shown on a 2 digit 7 SEG display. To start or stop the timer, a touch module can be pressed.
- The logic is implemented for Arduino.
- Arduino Nano is suitable for this project
- The 3D printing case models (soon to come) are also designed for the size of an Arduino Nano.
- Arduino Nano
- Poti
- 2x330 Ohm resistor
- Resisitive Touch module
- On/Off switch
- 9V Battery
- 2 digit 7 SEG display
- Passive Buzzer module
Please note the 7SEG should be two-digit. I just couldn't find a module in fritzing for it. The wiring is the same.
