In 2008, there was recorded to be nearly 2 million turtles kept as pets in the U.S!
Red-eared slider are ectothermic - they rely on the environment to regulate their temperature.
Water Temperature: 75°F - 85°F
Basking Area Temperature: 85°F - 96°F

Regulates the water temperature at a target value.
Regulates the water temperature at a target value.
Drawback:
Drawback:
No way of warning users if a disturbance causes water temperatures to exceed a certain level
Cannot reconcile for high temperature levels
Turns on basking lamps on and off based on timer circuits.

Does not monitor the temperature of the tank
Project Idea: To create a system that can monitor the tank's temperature and warn owners if temperatures exceed a certain range. In addition, the system uses a relay circuit to the power the basking lamp based on the sun cycle and also regulates the water and dry temperature.

Relays:
Control AC power from wall outlets. We are able to use two relays at once with the I2C protocol by bridging the solder joint on one of the relays to change its byte address to 0x19 instead of 0x18.
