Brand new to electronics? Drop your first question here. There are no dumb questions - only ones with not enough context.
Useful info to include:
Sample first questions: How do I know which Arduino to buy? Why doesn't my LED light up? Is breadboard wiring different from prototype wiring? What's the difference between 3.3V and 5V?
Useful info to include:
- What you bought (board / kit / module name)
- What you're trying to do (just blink an LED? read a sensor? drive a motor?)
- What you tried so far
- What happened vs what you expected
