It is designed to build a controller to control the bath temperature of a petri dish. The device will be used by student lab of neurobiology to conducting experiments on fruit flies’ thermo channels. An ideal device should have the following feature: easy to use, small development budget (less than $100) and satisfying the performance requirement for conducting experiments. The project is based on an atmega-1284 microcontroller as the main control unit with a PID control algorithm running inside. The petri dish’s bath temperature is heated or cooled by a Peltier Plate. A Thermistor is used as the temperature detection device and sent feedback to the microcontroller regarding to current bath temperature of the petri dish. All components are connected with analog circuits to form a close loop feedback controller in order to dynamically control the petri dish’s bath temperature. Graphic user interface is built with MATLAB to provide easy user access and monitoring.
