7. Electronics design¶
Use the test equipment in your lab to observe the operation of a microcontroller circuit board
We used the multimeter to check the microcontroller , Button , and LED voltage when powered.
|VCC - GND||4,9V|
|Blinking LED||0V to 4,9V|
|Button voltage||5V released, 0V pressed|
When measuring the voltage in the LED during the blink program, we needed to lower the blink speed to get a readable measure.
The same measure with an oscilloscope.
