 ## Calibrating the Touchscreen
 
-Run the program given in [this](https://github.com/Aditya-A-garwal/Arduino-TFT-3-5-Touch-Calibration) repository to calibrate the display. The display should print the values of 4 constants to the Serial Monitor. Copy and paste these values in ```src/constants.h``` to calibrate the touchscreen.
