Input Devices#

Group assignment#

  • Probe an input device(s)’s analog and digital signals
  • Document your work (in a group or individually)


Digital signal#


From Arduino, we sent digital signal, char data. In this case, it shows H = 01001000 from left to right. Upper lines means 1, lower lines means 0.

Analog signal#

Try to probe light sensor’s analog signal. Connect the copper line to the microcontroller and the hook chip with lead wires, also ground lead to the ground.
