Is a bit of warmth normal for beginner circuitry?

So beginner arduino user here, using arduino mega 2560. my question is. i'm using a RGB LED, to blink the red LED, ( with a resistor obviously) and it drew 7.78 mA. the chip got a bit warm, measured with a thermocouple i got like 30 degrees Celsius. is everything fine?

With only 7ma, 30° sounds wrong.

Show us a good schematic of your circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.

Which chip?

ATMEGA2560 ofc

schematic simulation:


and a 0.25W resistor from the elegoo kit.
and a multimeter to measure current.
also update it's 8.70 mA**** connection with breadboard issues...

Does the chip get cool/cold if the LED is removed from the output ?

nope. dang.

Yes, what resistor?

What do you actually know about resistors? :face_with_raised_eyebrow:
