Assignments

Group Assignment

  • Measure the power consumption of an output device

Individual Assignment

  • Add an output device to a microcontroller board you’ve designed and program it to do something.

For this assignment, I have added an LED as an output device to the board. the input is the photodarlington sensor. the logic is to sense light and turn the output device (LED) on.

Here is the schematic design of the board designed in Kicad software

This is the board after assigning footprints and routing

3D view of the designed PCB After designing the board in Kicad,I saved it as SVG file which was converted in png file later. The PNG files were sent in mods to generate RML files that the Roland machine can understand.

The RML files were sent to Roland for PCB milling.

This is the hero shot after soldering the electronic components.

After programing , the LED turned on as an output device.
