What is the standard size for the Tinkerblock TK01 LED?

The Tinkerblock TK01 LED is an F10 LED, which means it has a diameter of 10mm. This makes it one of the largest LED sizes available.

Can the Tinkerblock TK01 LED work with both 3.3V and 5V microcontrollers (MCUs)?

Yes, the Tinkerblock TK01 LED is designed to work with both 3.3V and 5V MCUs. The resistor is calculated to ensure maximum brightness at 3.3V. When connected to a 5V MCU, the LED may appear slightly dimmer.

Can I connect the Tinkerblock TK01 LED to a Lonely Binary UNO R3's analog pin?

Yes, you can connect the Tinkerblock TK01 LED to any of the Arduino UNO R3's analog pins, as these pins can function as digital pins. However, digital pins cannot be used as analog inputs. Therefore, you can connect the LED to either digital or analog pins on the UNO R3 as needed.
