Use the test equipment in your lab to observe the operation of a microcontroller circuit board.
We programmed the board with the code for blinking the LED
We attach the alligator clip to ground and the probe to the LED pin
We pressed “Autoset” - it didn’t help to calibrate the scale, so we did it manually instead.
We changed the scale for X (time) and Y (Volt)
First we tried X=250ms, Y=2V
We pressed “Run/Stop”(to stop the graph) and discovered an error.
The LED was blinking too slowly (875ms when it was supposed to be 100ms).
We re-burned the bootloader and uploaded the code again, since the clock wasn’t working right.
In the code we set the “Delay” to 1000ms (1 sec)
We changed the scale to X=500ms Y=2V
The signal on the oscilloscope changed about every 2 squares, meaning the reaction of the LED was a bit imprecise.
We have learned that the LED is a bit slow.
