+pid temperature controller using the pi pico.
+
+## steps:
+* learn RTIC, get 2 leds blinking at two different rates, and an led toggling on button press with interrupts.
+* learn to interface with i2c, print temperature measurements to serial
+* learn to interface with rotary encoder, print rotation directions to serial.
+* learn to interface with lcd, print temp measurements and rotation to lcd.
+* develop pid loop to control solid state relay, with temp from temp sensor and target temp from rotary encoder.
