let me start by saying... I am brand new at this...
ok... so I think I may have broken my board.
I was working on project 6, using a servo, and got it successfully working. The main power source has been USB to my laptop.
I was curious if I could run it off a 9v battery and after trying a few different spots, the servo was not responding correctly, and then stopped altogether.
I cleared everything and tried running the simple blinking program again, and pin13 led lights up slow and not completely. When I upload the program, the led is bright so I know it's not broken there. But once it tried to run, it's not working.
/*
Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:
