# 17. Case 13: Remote Control with Joystick:bit#

## 17.1. Purpose#

• Use the joystick:bit to control the Cutebot.

## 17.3. Software Platform#

MicroSoft makecode

## 17.4. Programming#

### Step 1#

• Click the “Advanced” to see more choices in the MakeCode drawer.

• A codebase is required for Cutebot programming, click “Add Package” at the bottom of the drawer, search Cutebot in the dialogue box and download it.

• A codebase is required for Joystick:bit V2 programming, click “Add Package” at the bottom of the drawer, search joystic in the dialogue box and download it.

Note: If you met a tip indicating incompatibility of the codebase, you can continue with the tips or build a new project there.

### Step 2: Joystick:bit Programming#

• Set “radio set group” to 1 in the On start brick.

• The scope for X and Y is 0~1023, the theoretical value is 512 if the rocker is in the middle place , in this way we need to make 0~1023 map map in the scope of -100~100.

• Set x whose value is given by “acceleration (mg) x” exactly divides 10 to the radio value in forever brick.

• Set y whose value is given by “acceleration (mg) y” exactly divides 10 to the radio value in forever brick.

• The scope of the acceleration value is 0~1024 , which can be regarded roughly as the speed value in 0~100 after dividing 10.

### Step 3: Cutebot Programming#

• Set the “radio set group” to 1 in the On start brick. Items must be the same with the remote control for the correct match.

• Drag two “if” bricks into the on radio received brick and judge if the radio revived value name is x or y

• If the radio received value name is x, it is the data for X and then save the value in the variable xValue.

• If the radio received value name is y, it is the data for y and then save the value in the variable yValue.

• In forever brick, set the left wheel speed to yValue+xValue and right wheel speed to yValue-xValue.

## 17.5. Result#

• The rocker controls the movement of the Cutebot.
