Need help with this one. I'm following a tutorial that explain how to create a circuit which makes the diode to pulse. Not sure what I'm doing wrong but for some reason it doesn't works

the time base to real time (1 s/s) 2. The led resistor needs to be approximately 300 ohms to allow 20 mA led current. 3. A 20 uf timing capacitor would be better choice. See

Your circuit is basically correct, just a few minor changes are required, 1. Adjust the time base to real time (1 s/s) 2. The led resistor needs to be approximately 300 ohms to allow 20 mA led current. 3. A 20 uf timing capacitor would be better choice.
