Enter the Value you got here from Step 5. Activity 1.2: Actual voltage across 3.3V breadboard pins. Explain in around 100 words why you think the value read by a multi meter on a circuit, may be different to a simulator value such as TinkerCad. If the read value is 4.84V on a 5V supply, what would be a sensible tolerance to quote, explain your answer.
