temperature-display

An Arduino project that displays current and historic air temperature measurements.

The temperature_display.ino Arduino sketch programs a Trinket M0 to capture air temperature measurements every 15 minutes using a TMP36 sensor. The latest measurement, along with a graph of the previous 24 hours of measurements, are shown on an I2C OLED display.

Components
