I'm trying to run what I thought was going to be a simple code, but for some reason the output is incorrect. I've used Simulink and Arduino Uno in other projects and it works great. This time I'm using an analog input voltage to determine which of my eight LEDs will light up. Like how a fuel gauge works, as you have more fluid, more LEDs light up. So in Simulink, I have an Analog Pin (0) reading voltage (fuel level). The line coming out of that block is then split into 8 different Matlab Function blocks. Inside each Matlab block is an if/then function, where if u > i, then y = 1, however, if u < i, then y = 0. The variable i is an integer that is different for each Matlab block. The output for each block is connected to its own Digital Output block.
When I send the code from Simulink to the Arduino, all of the LEDs turn on, regardless of how much fluid is in the tank. I can run a different code from Matlab to the Arduino, and the LEDs light up correctly as the fluid goes up and down, but I want to have a stand-alone device not connected to my computer, which is why I want to use Simulink. I tried to put this different code into a single Simulink Matlab Function block, but the code wouldn't load to the Arduino, so I separated the code into eight separate blocks. At least now the code is being sent to the Arduino and I'm getting some kind of response.
Any suggestions would be greatly appreciated! I didn't think I would have spent so much time on what I thought would take ten minutes to finish!
Thanks,
Chris
