// I am using this sketch with two different sensors- TP1521 B and C. B doesn't read visible light as much as C.
int sensorPin = D3;    // D3 is also A3 on the pinout- its an analog input pin to read the data from the sensor
int sensorValue = 0;  // sensor variable to store the value coming from the sensor
 
void setup() {
  Serial.begin(115200); // initializes serial communications at 9600
}
void loop() {
  pinMode(sensorPin, INPUT);
  sensorValue = analogRead(sensorPin); // reads the sensor value-- must be connected to ADC pin 
  sensorValue = map(sensorValue, 0, 4095, 4095, 0); //creates a visualization of the data over time. This range reflects the bits in the RP2040 chip's ADC GPIO
  Serial.println(sensorValue); //Print to the  Serial Monitor the data in sensor Value
  delay(500); // I wanted to track teh data quickly
