LightBulb
Step 1 @unplugged
Let's start by doing something simple. Let's light up the Light Bulb on the BrainPad.
Step 2 @fullscreen
You'll notice the project begins with a ||loops:forever|| block. Anything we place inside this block will keep running forever in the program.
loops.forever(function () {
})Step 3 @fullscreen
Let's drag a new block into the ||loops:forever|| block. In our block menu under Light Bulb, grab the ||lightbulb:set light bulb to|| block and drag it into the ||loops:forever|| block.
forever(function () {
lightbulb.setColor(0xFF0000)
})Step 4 @fullscreen
If you look in the simulator, you'll see that our Light Bulb is now RED. Click on the RED bubble inside the block we just added. Here you'll be able to change the color of the Light Bulb to any of the colors available on the color pallette.
forever(function () {
lightbulb.setColor(0xFF0000)
})Step 5 @fullscreen
But what if the exact color you want isn't on the pallette? We can add parameters to change values, and create our own color. To accomplish this we need to drag a ||lightbulb:red green blue|| block inside of the ||lightbulb:set light bulb to||.
forever(function () {
lightbulb.setColor(lightbulb.rgb(255, 255, 255))
})Step 6 @fullscreen
Let's suppose we wanted to make our LED blink every second. To do this we will need to add a ||loops:pause|| inside our ||loops:forever|| block. We'll also need to change the parameters value inside the block to 1000 ms, but the Light Bulb still won't blink. Can you guess why?
forever(function () {
lightbulb.setColor(lightbulb.rgb(255, 255, 255))
pause(1000)
})Step 7 @fullscreen
Our Light Bulb doesn't blink because we never turn off the Light Bulb anywhere in our ||loops:forever|| block. We can accomplish this by adding a ||lightbulb:set brightness|| block right after our ||loops:pause|| block. It defauts to a value of 15, we need to change this to 0. This will turn off the Light Bulb.
forever(function () {
lightbulb.setColor(lightbulb.rgb(255, 255, 255))
pause(1000)
lightbulb.setBrightness(15)
})Step 8 @fullscreen
But Our Light Bulb still doesn't blink properly. That's because we never tell the BrainPad how long to leave the Light Bulb off. So right after ||lightbulb:set brightness|| block. We need to add another ||loops:pause|| block
forever(function () {
lightbulb.setColor(lightbulb.rgb(255, 255, 255))
pause(1000)
lightbulb.setBrightness(0)
pause(1000)
})Step 9 @fullscreen
We still need to turn the brightness back up. So we'll add another ||lightbulb:set brightness|| block to complete the task, and set it all the way up to 255 (100%). The Light Bulb on the simulator should be blinking, whatever color we created.
forever(function () {
lightbulb.setColor(lightbulb.rgb(255, 255, 255))
pause(1000)
lightbulb.setBrightness(0)
pause(1000)
lightbulb.setBrightness(100)
})

For some reason the words inside the "New, Try this First - LightBulb" tutorial (lightbulb.md) aren't translating correctly. It is the only one that apparently has an issue. It works fine in English. The Title and Inline code snippets are translating correctly, just the instruction in the tutorial are not as shown in the image below.
This is how we would expect it to look as seen in another tutorials shown below.
