7. Electronics design¶
Group assignment
Use the test equipment in your lab to observe the operation of a microcontroller circuit board
Measuring¶
We used the multimeter to check the microcontroller , Button , and LED voltage when powered.
Measures | Value |
---|---|
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.
