Finish the connections with Arduino. Components required. As by the above table we only need to look at these four lines for establishing a communication between an ARDUINO and LCD. The simplest and inexpensive way to display information is with an LCD (liquid crystal display). We don’t have to write a program loop to send the data BYTE by BYTE here. Using LiquidCrystal library with Hardware: For 16×1 we get ‘lcd.begin(16, 1);’. But it’s hard for noobies to use a potentiometer, as they run into different problems. Turns on the LCD display, after it's been turned off with noDisplay(). Share it with us! After uploading the code to your Arduino board, you can rotate the potentiometer to adjust the LED brightness and change the progress bar on the LCD. I see good reasons for wanting to connect LCD without potentiometer or even fixed resistors at all: when you just want to test a new piece; when you're in hurry, in place lacking anything but wires, or when you just don't want to bother with the question how to connect that resistor so it wasn't fragile, ugly, etc. STEP 3. We will use the digital pin 6 to control the contrast value of the LCD. Plug in the USB connector of the Arduino to power the LCD.
