Hello, my name is Ulysbek and im 13 years old, i am a total newbie at arduino. My arduino turns off when i connect my lcd1602 to 5v but when i took potentiometer off the lcd screen started to work. What should i do
it's the scheme i used and my result
You need to double check your wiring.
I don't think there's something wrong, i rebuilt it 3 times
How did you decide which pin to connect the potentiometer to? Do you have specifications or a data sheet for the display?
I know that potentiometers have right, left, and central pins so i just looked at my potentiometer and it similar to one that is on scheme, just the central pin is at the back so i did the same as the scheme showed and i thought it would work
looks like the breadboard is wired to 3V3 and not +5V
Can you show me where is it? I just dont get how breadboards work
The "3v3" pin is next to the "5v" pin. You want the 5v pin... which looks like you are using a blue jumper wire. That jumper wire is going to the breadboard on the "RED" column/rail, making it a "5v rail". Your GROUND (black) jumper wire is going to the breadboard on the "BLUE" column, making it a "Ground Rail/column." To the right are the component channels/rows... green and orange... they are perpendicular to the Rails and allow continuity to anything plugged into those component channels.
