Water Temperature Controller
Macleans College, Auckland
The Shower Temperature Controller demonstrates how you can monitor the temperature of the water in your shower and adjust it according to what you like. It uses a thermistor to detect the temperature of the water and a small LCD screen displays the results.
I was inspired to create my project after my research showed that my idea had never been used to measure the temperature of shower water before. It was great fun thinking about all the different ways I could solve the problem of displaying the temperature of the water.
Programming the PICAXE to display on a serial LCD was difficult. I never had true success with the LCD because it was nearly impossible to display variables on it. I later switched to an LCD display with a driver on it. This greatly simplified my project and allowed me to do something cool with the bottom line of space on the LCD display itself.
