Why is my LCD screen not working Arduino?
If your wiring is 100\% correct, then check the wires themselves. As in, are they making a secure mechanical and electrical connection with the LCD and with the pins on the Arduino. Try using a breadboard instead of male-to-female jumper wires. Check that the Arduino is working properly.
Can we connect LCD to Arduino without potentiometer?
You can be displayed in an LCD monitor without a potentiometer & Resistor.
How do you connect LCD NodeMCU without I2C?
You have to just hookup pins in NodeMCU just same as you have done with Arduino board. You can use any GPIO for these connections. Now, upload the code using Arduino IDE as explained earlier. Code is same as for Arduino board which can be found in Liquidcrystal example.
How can I tell if my 16X2 LCD screen is working?
HOW TO CHECK WHETHER 16X2 LCD WORKING OR NOT
- Are you worried whether your 16×2 Lcd is working or not?
- >> Connect the pin vcc pin to 5v.
- >>Connect pin Vee and gnd pin to ground.
- >> Connect Led+ to 5v.
- >>Connect led- pin to ground.
- If your Lcd is not working well, then both the lines will be bright shown below.
Why LCD screen not working?
There might be a short circuit between adjacent data lines or it might also occur if some of the data lines are not properly connected. So make sure you examine for short circuits between adjacent tracks going to LCD display. Connect the pull ups from LCD lines to +5V power supply (LCD supply).
How to use 16×2 LCD interface with Arduino Uno?

How many pins are there in a 16×2 LCD module?
It is also known as I2C Module. It has total of 20 male pins. 16 pins are faced to rear side and 4 pins faced towards front side. The 16 pins for connect to 16×2 LCD and the 2 pins out of 4 pins are SDA and SCL. SDA is the serial data pin and SCL is the clock pin.
How to control the contrast of 16×2 LCD display?
The 16 pins for connect to 16×2 LCD and the 2 pins out of 4 pins are SDA and SCL. SDA is the serial data pin and SCL is the clock pin. The rest 2 pins for power supply (Vcc and ground).There is a POT on the I2C Module. We can control the contrast of the LCD display by rotating this POT.
What is the best LCD display for Arduino?
As there is an enormous range of Arduino-compatible LCD displays on the market, you’ll have to keep in mind that the device drivers, pinouts, interfaces et cetera can vary greatly from one model to another. The monochrome Hitachi HD44780-based LCDs can come bundled with or without a serial interface board.
