Hi All,
I made a simple barometer for my son's Cub Scout belt loop:
The code is on github at https://github.com/drf5n/BarometerLCD
I really liked powering the sensor and LCD directly from the Teensy to do minimal extra wiring. Driving the LCD's contrast input with a PWM on DIO14 was fun too.
Under the board is a battery holder with 4 rechargeable NiMH batteries.
The LED isn't doing anything, but I do use it to jumper DIO0 to reset the saved pressure.
