hi,
I want my LCD Display to show some Text while LED s are. I tried it with an Shift register 74hc595 but because the IC and the LCD needed to much power, I kicked the 74hc595 out. But now just the LCD doesn't even work...
I mounted everything correctly, but after a short periods of time, my Arduino UNO slowly shuts down and disconects from my Computer.
So I measured the Current at VSS input and it was about 1 Amp.
I bought another Display, but the same.
Did anyone has the same problem or is here someone how can help me?
Pleas answer...
It's likely that you connected something incorrectly. Also some 1602 devices have different supply voltage requirements compared with others.
Best to show your exact setups and connections.
