Building Circuits With Tinkercad:

Assignment: Make a circuit on a breadboard with components in the kit. Use a multimeter to measure the voltages in your circuit. Use Ohm's law to calculate the current through some part of the circuit. Simulate your circuit. Use the Microcontroller Analog in (ADC) to measure the voltage of a potentiometer, or other voltage-divider-based sensor. Document your work and learning.

Some of the tutorials I walked through:

1. LEDs & Breadboards With Arduino in Tinkercad

2. You can learn Arduino in 15 minutes.

3.Fading LED With Arduino in Tinkercad

4.RGB LEDs With Arduino in Tinkercad

My Circuit:

1. It is just a basic design with 5 led and 5 resisitors in series attached to a breadboard and a arduino microcontroller. I also found the current flowing through the circuit using ohm's law. As it was a series connection, current flowing through the circuit will be same throughout the circuit, but voltage will vary all over the circuit.

Ohm's law - Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship.
