Hi, We have a system, where we need a micro to take 6 ports either high or low, depending on conditions. We also need it to have 3 ADC inputs. We also need it to have three digital input pins.
We wish to use an Arduino (Uno?) to develop the code. But when it comes to doing the PCB, we don’t want to mount the Arduino on the PCB. Instead We just want to put the Arduino’s micro on the PCB, along with the programming connector. Can we do this? Which is the best (cheapest) Arduino to do this with?
Also, we want to start writing the code for the Arduino now? Can we do this, and then buy the Arduino later? Is there like an emulator for the Arduino? So we can see if the code would work, before buying the Arduino?
Also, eventually we want wifi connectivity...can we do this with the Arduino Uno?
