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.
- TMP36 VIN to Trinket M0 3V
- TMP36 VOUT to Trinket M0 pin 4 (A4)
- TMP36 GND to Trinket M0 GND
- OLED SDA to Trinket M0 pin 0 (SDA)
- OLED SLC to Trinket M0 pin 2 (SLC)
- OLED VIN to Trinket M0 3V
- OLED GND to Trinket M0 GND
