Today at first we experimented with circuit designs with capacitors, resistors, and diodes and used the oscilloscope, the white box on the left, to measure what the resultant voltage would be if passed voltage as a sine function. We then built the same circuits in a circuit simulation software and compared the results. Afterwards we did activities with Arduino programming, making programs to write text or show images on a screen or to read inputs from a joystick. Additionally, some designs were 3D printed with the goal of being able to withstand 50 pounds of force applied on a cantilever beam, upon which testing will commence later.
