Input devices

Group Assignment:

• Probe an input device(s)’s analog and digital signals

• Document your work on the group work page and reflect on your individual page what you learned

For this week’s assignment we chose to use two input devices, an ultrasonic distance sensor for the digital input and an IR Phototransistor for the analog input.

Digital signal probing

For probing the digital signal we used an oscilloscope as shown below.

Here is an acquisition of the sensor data

Analog signal probing

For probing the analog signal we used an oscilloscope as shown below.

Here is an acquisition of the sensor data
