So i am a bit new to creating any sort of prototype that isnt directly already on an UNO board. Here is a shot of an LED driver that i have made, however i didnt factor in the feature to program it directly. I want to add a header to allow me to do this, however I have been getting lost with diffrent tutorals and terminology. Currently i pull the chip out of the uno and into this board and it works fine. Unfortunaly i didnt realize that one of the pins I am using is D11, which is "MOSI" .... is this pin critical to uploading sketches?
I will be in total using 3 PWM pins (D9, D10, D11), Two analog inputs, and 1 digital pin.
Is there a way to get around this without having to desolder D11? Is there a good guide somewhere which explains exactly what I need to connect to my UNO? Some guides refer to plugging into the pin breakouts, while others refer to the two diffrent 6-pin headers on the UNO, yet im still a bit lost.
