Week 4 Update
The long awaited lab update😲😲😲 Lab 4: I had to fumble through the beginning because I still have not been able to go to the lab and use the multimeter (happening Monday!!) But I watched the full lab 2 video just so I could understand the voltage divider better, and the potentiometer worked perfectly. Adding the LED was a struggle at first, but it was just wiring errors on my part, and eventually I was able to control the brightness with the potentiometer. Here is the completed setup: I'm still struggling to comprehend why we divided by 4 to define the brightness value from reading. I assume it has to do with units of measurement, especially since I used 10k resistors for part 1 and switched to 220 for the LED. Need clarification on this. Thanks to our talk in class about PWM, though, I can see how pins 9 and 13 differ. Overall, I'm getting more confident with circuitry, and I think this will make more sense after I connect the dots with lab 2. Lab 5: Lab 5 wen...
