I do plan to later add more fans and peltiers, but for now, I just want his working. The Small fan is only powered on to cool the Peltier and can remain on high when ever the Peltier is turned on, otherwise it stays off. When it LED 5 is blue, the Peltier is polled in one direction, when LED 5 is red, it is polled in the other direction. Button 3 controls the power level of the Peltier and the Small (4cm) fan as well as turns the, on and off and scrolls through RGB LEDs 6, 7 & 8 to indicate the power level of the Peltier (Low, Medium, High, Off).Button 2 controls LED 5, switching it from Blue to Red and back.Button 1 controls the power level of the large fan and scrolls through LED's 2, 3 &4 to show the power level.There are three tactile push button switches, each have there own function: RGB LED 2 turns on to indicate fans power level (Low, Medium High, no off).The Large (12cm) fan turns on (at low power setting).
RGB LED 1 turns on with a certain colour to indicate power is on.The idea is that when power is turned on, the following will happen: There are 8 COMMON ANODE RGB LED's coming off the Tlc units as well as 3 L293B h-bridge units (one controlling a 12cm fan, 1 controlling a 4cm fan, and one controlling a Peltier unit)
I am new to this so bare with me as I know this is a huge project to take on.Įssentially I have an arduino nano hooked up to 2 TLC5940 units that are daisy chained and 3 tactile push buttons. As part of the process though, I have had to label some functions under a made up name, as I don't know what to call them. I have written this up so far, and have got it looking roughly how I want it.
