Santa Stand Reminder
This is a 25 minute “stand” timer. After pressing the button, the green light will turn on. Get in your flow. After 25 minutes the green light will turn off and the red light will turn on. This is your reminder to stand up. There’s no noise, nothing flashing. Stay in your flow if you’re there but if/when you look up and you see red it’s a reminder to stand up and stretch your legs.
Everything you need should be in the box and pending how rough the ride from the North Pole was it should be simple enough to finish assembly.
What’s in the Box:
- 1x Arduino Board (e.g., Arduino Uno)
- 2x LEDs (1 green, 1 red, as bright as Rudolph’s nose!)
- 1x Jolly Push Button
- Resistors:
- 2x 220Ω (blue)
- 1x 1000Ω (beige) (for LEDs and the button)
- 1x Breadboard (no, not the gingerbread type!)
- 1x 9v Battery and leads
- Handful of jumpers
