Use Stage Button to Control HaloCode Remotely

We will create a new project combined with Scratch Stage Programming. Use the button on stage to control HaloCode remotely.

Add User Cloud Message Blocks

Under "Sprites", click "+" in the Blocks area. The Extension Center page will pop up. Click "Add" to add User Cloud Message blocks.

Step One: Program Stage Button

1. Under "Sprites", click "×" to delete "Panda" (the default sprite).

2. Click "+" to add a new sprite. From the pop-up Sprite Library page, search and choose "Empty Button1". Click "OK".

3. Choose "Empty Button1", and drag an Events block when this sprite clicked to the Scripts area.

4. Add a User Cloud Message block send user cloud message () and name the message "light_on".

5. Let's add some special effects to the button. Add a Motion block change y by () and set the value to "-2". Add a Looks block set color effect to () and set the value to "-10".

6. Add a Control block wait () seconds and input "0.2". Drag another Motion block change y by () and set the value to "-2". Then add another Looks block set color effect to ().

Step Two: Program HaloCode

Connect to the Internet

1. Under "Devices", make sure "HaloCode" is selected. Drag an Events block when HaloCode starts up to the Scripts area. Add a Wi-Fi block connect to Wi-Fi () password (). Input Wi-Fi SSID (Wi-Fi name) and password.

2. To ensure Wi-Fi is successfully connected, we need to add a Control block wait () and a Wi-Fi block Wi-Fi is connected?. We want to know when Wi-Fi is connected, so let's add a Lighting block all LEDs light up () to make the LED ring lights up green.

Cloud Message Script

When HaloCode receives the user cloud message "light_on", we want the LED ring to light up red and then go off.

1. Drag a Wi-Fi block when receiving user cloud message () and input "light_on". Add a Lighting block all LEDs light up () and set the color to red.

3. Add a Control block wait () seconds and a Lighting block light off all LEDs.

4. Click "Upload" to upload the program to HaloCode.

5. Try clicking "Empty Button1" on the stage!
