Build a simple application using digital or analog input and digital output. This week’s assignment is very similar to my Fabrication homework last week which is build a flash light.

Here is the current diagram, design draft and final work:





So basically, this week I just need to improve the previous work: change the power source, use a breadboard.

Materials I used:


Current diagram:


Actual project:




Some thoughts:

1, When you use so many wires to build a circuits, always use different colours to mark positive and negative(ground). It’s the easiest way to avoid chaos and mistakes.

2, Drawing the circuits diagram first is really helpful (for me)!

3, Calculate the resistance and pick a right resistor.
