At least two of the available MakeCode Arcade handheld console’s have the facility to program two Light Emitting Diodes (LED’s) mounted on the console using the MakeCode editor.

**KittenBot Meowbit**

The Meowbit has two LED’s mounted at the top right corner of the console, just to the right of the power on/off switch.

LED1 - Green

LED2 - Red

The LED’s are not very big. The green LED shines through the outer casing but the red LED is very faint. You may have to remove the blue/orange outer casing to view them both better. The Green LED is to the left of the Red LED.

**TinkerGen GameGo**

The GameGo has two LED’s mounted in the center of the console just below the screen and labelled as indication LED’s.

LED1 - Blue

LED2 - Red

The LED’s are quite large and bright. The Red LED is to the left of the Blue LED.

**Tester Operation**

Press Button [A] – LED1 will light. Green on the Meowbit. Blue on the GameGo.

Press Button [B] – LED2 will light. Red on both consoles.

Press Button [Menu] – Both LED’s will flash on and off alternatively.
