 A digital clock and thermomter/hydrometer written in Arduino for the Raspberry Pi Pico using an SH1106 OLED dispaly and a BME280 environment sensor
 
+Pin definitions and display drivers (as long as the display is 128x64) can easily be changed in the code
+
+Theoretical battery life is ~153 hours (6 days 9 hours) with a standard 2000mAh 18650 Li-Ion battery, power draw is around 12.5-13.5 mA
+
+The battery level is read by the battery going into a simple 10k resistor voltage divider into ADC1
+
+The OLED display and BME280 share the same I2C lines into the Pico
