arduino/analog_shield/temperature/main.py

Prints the temperature from the shield's LMT84 sensor once a second.

Connect

JP4 on 5 V, JP1 on INT and JP2 on EXT (A3). With JP2 on INT, use set_output_pin("A0").

Uses

set_output_pin(), temperature(); delay()

# Prints the temperature from the shield's LMT84 sensor once a second.
#
# Needs analog_shield.py on the board, JP4 on 5 V, JP1 on INT (the on-board
# sensor) and JP2 on EXT (the amplifier to A3). With JP2 on INT, change the
# set_output_pin() line to "A0". Hold the sensor (U1) to see it warm up.
