the first OLED died and burned my Arduino Nano after about 1 days of working, also when they are connected the circuit doesn't work properly.
The second oled died after 2 days of working.
I'm pretty sure both of the OLED created noise in the circuit when they were connected.
Anyone had this problem?
What am I doing wrong?
Thanks.
Update:
I'm using Arduino Nano like this one: Arduino Nano
12V Power supply output 12V, 1.5A
The OLED accepts? (as written in the link above) Voltage: 3V ~ 5V DC
I suspect (and I maybe wrong) that the OLED killed the Nano, however the important thing I want to understand is why when the OLED is connected I get noise and the circuit doesn't work as expected, and why the OLED dies after short use.
Please read the forum guidelines to see what sort of information that we need to be able to help you and information on how to ask a good question.
Is the Nano a classic Nano or one of the newer ones like Nano Every, Nano33 iot, Nano33 ble? What happens to the Nano? How do you know that it is the Nano that is dead? Is there a particular component that fails?
Please post a wiring diagram or schematic. Written descriptions are always more ambiguous than a drawing. Hand drawn, photographed and posted is fine. Include all pin names/numbers, components, their part numbers and/or values and power supplies.
Are you using 5V on a 3.3V device?
It is unlikely that a LCD can kill a Nano. Look for a more reasonable cause.
I have had an OLED with pins thinner than others, and when placed in my breadboard for a long time, the pins lose contact. Maybe use good connecting wires? Soldering the OLED onto copper perfboard made the contacts good until the project was made permanent.
