Coding for the Arduino is done in the Arduino IDE interface.

Arduino IDE interface has case sensitive commands.

As we do not have access to the hardware, even if we write the programme in Arduino IDE, we will not be able to upload the programme to Arduino.

In that case, we will be using the tinker circuit interface to write code and run the simulation.

For writing the code in the tinker circuit, you can click on the code button to open the interface where you can write the code.
