Group Assignment — Week 9: Input Devices
Testing the Multimeter and Oscilloscope on an Input Device
Testing the Multimeter and Oscilloscope on an Input Device.
When the switch is not pressed, there is no reading, but when the switch is pressed a low resistance ranging from 0.3–0.5 ohm is observed.
This reading shows that there is a voltage reading of 3.289V when the switch is not pressed which goes to 0.0V when it is pressed.
Adjusting the horizontal reading on the oscilloscope allowed me to see the waves more clearly.
There is a secondary wave that fluctuates at the same rate as the LED lights with the blue light.
There is a noticeable difference in the distortion of the wave when switching between Blue and Red light. The Blue light appears to have less fluctuations and appears to be behind the primary wave. The Red light seems to have more distortion and appear to be in front of the main wave.
