As you might guess, it is bi-color too in blue/red. Note that if a very short program has been loaded to the S3, this light may not come on.Ĭharging LED - This LED is solid blue when the power is on, solid red when charging, and blinking blue/red when there is a charge fault or something wrong with your robot. This LED gives you useful feedback for charging your S3’s rechargeable battery. When you turn off your S3, the power LED turns off along with everything else. This particular LED is also bi-color in blue/red. When it blinks, this means your battery is getting low and needs to be recharged. Power LED - When your S3 is powered on, you will see the blue power LED light up and stay on. These two colors can be mixed as well, forming the color amber. They are called bi-color because they combine the ability to emit two colors (in this case red or green, depending on the direction that electrical current flows through the LED). In this tutorial, you will learn how simple and useful they are to program. In their simplest use they can be off, red, amber, or green. You can also follow along with the S3 startup guide that came with your robot, which has a section labeling the different parts of your S3.īi-color Indicator LEDs - These are the three LEDs at the back of the robot, directly below the S3 logo. We will begin with those that are easiest to find. What are they for? What do they mean and how can you learn to use them?īelow are photos of some of the S3’s LEDs. There are more inside the shell that you cannot see. You have likely already noticed that your S3 has several lights, especially if you’ve gone through the S3’s 8 pre-programmed demonstration programs. We will begin learning to use BlocklyProp by learning to control the S3’s lights, or LEDs. Now that you’ve gotten BlocklyProp setup to program your S3 robot, we can dive in! Programming, and the ability to change and write new programs, is what makes robotics so amazing.
