Output pin high toggeling
I was testing out a very basic circuit before I starting going to deep into building the rest of the circuit so I wrote a program to turn pin 15 on high and then used a 1 k ohm resistor to a LED. I noticed the LED blinking every once in a while. I used a voltmeter to check the pin out and noticed the voltage dropping randomly. I then tried it on pin 14 and the same thing happened. Am I missing something? Shouldn't the output voltage from the pin be 5V steady?
