The power is set by evaluating the received values from the temperature sensors for the interior of the device and the aluminium block. Additionally the arduino receives commands from the Raspberry Pi to turn the excitation LEDs on and off. |

They control the 450nm and 480nm LEDs. The channels are connected and turned on and off by the arduino board. |
- | * '''Peltier | + | * '''Peltier element''': A Peltier component transforms an applied power into a temperature gradient which leads to a hot surface on one side of the element and a cooler one on the other. The Peltier element connected to the aluminium block heats up the interior of the device to incubate the sensing cells at 37°C. |

The characteristic of the filter slide is selected depending on the frequency of the LEDs which are either 450nm or 480nm ones. We used '505 Sally Green' for the 450nm and '010 Medium Yellow' for the 480nm LEDs. |
