I am using the code from the Humidity/Temperature/Light sensor, modified by taking out the Humidity/Temperature sensor code because I don't have that sensor. I just wanted to see if I could get the readings from my photoresister to show up on Adafruit IO. The only other modification to the code was to put my Adafruit IO username and key in and I added an LED to light on my breadboard when the value of the sensor was below 500. Aside from not being able to get the data to my Adafruit IO dashboard the circuit is working perfectly, I can view the values from the photoresistor in the serial monitor.
I am at a loss as to why it will not connect and display the value on my Dashboard.
My code:
Code: Select all
int LDR = 0; //analog pin to which LDR is connected, here we set it to 0 so it means A0
int LDRValue = 0; //that’s a variable to store LDR values
int light_sensitivity = 500; //This is the approx value of light surrounding your LDR
