To have success make sure that you have completed PART 1.
Click here to watch the Part 2 video tutorial.
- Keep the code from Part 1 in place. Login to tinkercad.com and open your blink program circuit.
- Modify your breadboard so it looks like this – make sure that you change wire colors to match and use a 220 ohm resistor (look at the stripes – your resistor should have red-red-brown stripes):
- Run the blink code from Part 1 by clicking on Start Simulation in the top right hand corner. What happens?
- Modify the code, changing the delay values.
- How would you change the code to get different blink patterns?
Now go to Part 3 – Blinking Multiple LEDs.
