+//this task covers how to use the on-board temperature sensor in the RP2040 chip on the Raspberry pi Pico
+//it uses the analogue to digital converter (ADC) in the Pico to read the internal temperature of the RP2040 and
+//does the necessary data conversion to output the temperature of the chip
+
+//covers how to perform the required data processing to take the raw ADC output and convert it
+//into a voltage and then into temperature
+
+//the temperature sensor might not be calibrated so temperatures might differ in different
+//boards due to manufacturing inconsistencies
+//as such, if you will be using this in a serious project that requires an accurate temperature value,
+//I would recommend using an external sensor.
