Electronic design

This week group assignment was to observe the operation of the micro-controller circuit board. We have observed the micro-controller communication and the button de-bounce effect. We have spent some time trying to figure out the setting for the oscilloscope to capture edges.

Serial communication

We have observed the serial communication signal, moreover we clearly observed how signals would change when we send a different letter to the micro-controller.

Button De-bounce

When a switch is toggled, the button contact will move from one position to another, however the contacts are usually made of spring metal thus this will force contact to bounce apart one or more times before making a steady contact.

 

The de-bounce for the switch we are using is actually minor compared to other switches.
