Hello,
I'm new to the forum and need your help.
I have an "Arduino Pro Mini Mainboard" here with the 4 LEDs soldered to pinouts A0, D15, D14, D16. GND is connected to A10.
One LED doesn't really work in round light mode, the one on A0 doesn't light up at all.
When I test the 4 SMDs manuelly not with arduino they work great.
Someone else built it. Unfortunately, I don't have the arduino code.
Does anyone have the time and interest to create an Arduino code for an RC rotating light?
Many thanks
on Pro Mini not present
why?
so how know LED what you want? why you expect something will light up for no reason?
Welcome! Sorry to say nor do we. You might be lucky and your Arduino is still OK. You must have a resistor or some other means to limit the current. Driving it directly from a pin as you indicated can destroy or damage the processor. Same goes for connecting an output to ground. Without the code we are at a loss.
Can you post the annotated schematic?
Something wrong there!
The pro mini does not have an A10 and A0 is the same as D14.
Where did you get those numbers?
Are you sure it's a pro mini?
Hi,
for better understanding i had made 2 Pictures.
Problem if i check the 4 SMDs all are working fine.
Only 3 are working as rotating light. I want to have 4 as rotating light.
I dont have the code form the developer. Sorry for the late answer.
that pin is not GND. desolder it. show schematic of this 4 SMLED lamp. or you can show pictures where you check each LED.
Have you looked closely at rotating construction vehicle lights? The light does not rotate! The reflector behind the light rotates and either reflects the light or shields the light as it rotates. That way there is no need to twist the wires as the light rotates!
Maybe you want to logically rotate a light. That is to say, all the lights are fixed. Each light is logically enabled, then disabled... then on to the next light.
Do you have a clean Micro so we can see the pin labels?
Post some info (link to datasheet or seller's web page) for that LED.
