My thinking for the 19 and 22 is that the final temperature should be around 20°C to 21°C, but either way anything from 19-25°C is fine.** | My thinking for the 19 and 22 is that the final temperature should be around 20°C to 21°C, but either way anything from 19-25°C is fine.** | ||

**Another reason for the not-so-strict heating in my pseudo-code is that the heat mat will take about 20-30 seconds to reach full heat. I’m not worried about this as it is never hotter than about 32°C, it will take a while to heat the liquid inside, and, conversely, it’ll take quite a while for the liquid to cool down. Hence, while the heat mat may be on for a little while it should need switching on/off only every few hours, at least, so it’s not like I’d be switching it on and off every few minutes. Well, that’s the theory. We’ll see how that pans out in the practical phase.** | **Another reason for the not-so-strict heating in my pseudo-code is that the heat mat will take about 20-30 seconds to reach full heat.

I’d like to have an alert system where I can get an SMS/email should the temperature go haywire. This is a possibility using ThingSpeak and Twilio, but is not something I’ve tinkered with before and will leave this to the end as it’s not critical.** | I’d like to have an alert system where I can get an SMS/email should the temperature go haywire.

Lighting is not critical, and will be manually controlled, so I’m not too worried about this. This will be a strip of 12V LED lighting with a transformer and a switch. No need for the Arduino to control the lighting. One major consideration for the lighting though is that it must be removable as the vessel has to be bleached sterile after use. I’ll probably just attach the light strip(s) to the vessel with some tape or blu-tac.** | Lighting is not critical, and will be manually controlled, so I’m not too worried about this.

As a quick visual-at-a-glance aid, I may add some LEDs to show if the temperature is within a certain range. Maybe between 20-22 could be a green LED with 25+ being red. Maybe 19 or less is a yellow LED.** | As a quick visual-at-a-glance aid, I may add some LEDs to show if the temperature is within a certain range.
