Countdown timer Raspberry PI

Job ID: 36207850

Budget: $10 – $30 USD

I like to create counter timer using Raspberry PI or something with HDMI display port.

We use the timers for keep track of mixing product with several ingredients. Each ingredient has own define time.
The Raspberry PI will display on TV screen. It will display past ingredient if there are any otherwise will be blank.
The center will display the current timer and next coming up timers will also display.
There are several buttons for enter time, ingredient name, start and stop. I only shown 4 on the pdf, may be needed few more.
