I want to use LEDs for my C3PO eyes/ How do I drive three 2.2V LEDs from a single output channel safely with the IO Tiny?

To drive three 2.2V LEDs from a single output channel safely with the EZ-B IoTiny, you will need to use a resistor to limit the current. The resistor value will depend on the voltage of your power source and the desired current for your LEDs. You can use an online LED resistor calculator to determine the appropriate resistor value.
Once you have determined the resistor value, you can connect the LEDs in series with the resistor to the digital output port on the EZ-B IoTiny. Make sure to connect the positive lead of the first LED to the resistor, and then connect the negative lead of the last LED to the ground pin on the EZ-B IoTiny.
In your ARC project, you can use the Set Digital skill to turn the digital output port on and off to control the LEDs. Remember to set the port to high to turn the LEDs on and low to turn them off.
