So i want to design a shield for an Arduino Uno. Or to be more precise, i already have designed a shield for an arduino, but now I have some questions:
1.) I designed the PCB with Eagle Cad. So I installed the SparkFun Library and started working. But now I have my doubts. The shield basis you get via the library does not align with the correct pins on the Arduino Uno. Is that normal?
2.) I had to design a own part at one time. But i don’t know if i made it correctly. Would somebody mind to control is for me? Here is the Datasheet and the file is beneath.
3.) In general i’m not sure if the things i did were correct. Would somebody maybe be so kind and give a brief look over my circuit?!
Goal of this shield is it to output 24 10V PWM Signals. These will be used to control a Dimmer for Stage-lightnings.
To do this I used Op-Amps, a Voltage Converter to reach the supply Voltage and Shift Register to get the required amount of 5V outputs.
