Learn how to easily adjust the contrast of a 1602 LCD display using Arduino. In this quick tutorial, I’ll show you a simple trick to control the contrast electronically, without relying solely on the ...

Power and Ground: Connect the LCD’s VSS to Arduino’s GND. Connect the LCD’s VDD to Arduino’s 5V. Contrast Adjustment: Connect the middle pin of the potentiometer to the LCD’s VO pin. Connect one side ...

The adjustment control for the contrast of an LC-Display is typically a 10-k potentiometer. This works fine, provided that the power supply voltage is constant. If this is not the case (for example, ...

Wire the LCD to 5v, the CCS811 to 3.3, share ground among everything. LCD's and CCS811's SCL go to Arduino's SCL. LCD's and CCS811's SDA go to Arduino's SDA. You might need to play with the contrast ...
