Fab Lab Ciudad de México

Mexico City

Group Assignment  – Electronics design - Querétaro

General objective (group assignment):

 

  • Use the test equipment in your lab to observe the operation of a microcontroller circuit board

 

The Fab Lab Queretaro machine used:

 

  • Osciloscope

 

 

 

 

 

 

 

 

 

Development

This is the board we use to measure is from luis hernandez you can check his individual asignment.

Reference: http://fabacademy.org/2020/labs/ciudadmexico/students/luis-hernandez/

And this is the schematic of the board we just wanted to measure the dropage of voltage on the LED.

Here’s the exersise on this.

Here’s a screenshot from the osciloscope we use on the right side of the screen we actualy see that it takes 1ms aprox to the LED to switch state.

And here we can actually see that the voltaje on the LED is 4.8V this is because the voltaje used for the micro to opérate causes a litle drop from 5v to 4.8v.

 

Results

 

Zero analogic volts is equal to zero in digital signal and 4.8 volts is equal to one in digital signal.
