In lesson 3, it says that with this schematic mounting, the led on board and the led connected to pin 13 have to alternate blink, but it doesn't happen with my set up. The connected led just turns off and doesn't blink. I've checked voltages with a multimeter and it shows 5V when current is high (onboard led on) and 0V when low (onboard led off).
Is it that i'm just dumb or could be something wrong?
