Learn to build simple circuits on a Propeller Activity Board or breadboard with a Propeller FLiP module. Create BlocklyProp graphical programs for blinking LEDs, controlling LEDs with pushbuttons, playing notes on a piezo speaker, and more. You will be building real-world STEM skills!
Build simple circuits on the Propeller Activity Board, and write Propeller C programs to interact with them. Blink lights, beep a speaker, measure voltage, and more.
Ever wondered how your fitness tracker is able to measure your heart rate? Learn how build a finger-clip device to observe and measure your heart rate using LEDs and a light sensor.
Each QTI sensor is connected to a post that is mounted on the underside of the chassis. This positions the sensors right above the ground surface.
Figure 1 below shows the schematic for the Magic BS2 board, and Figure 2 displays the optional mounting bracket assembly for the LCD display.

It is essential to test the whisker switches before programming your robot to navigate with them. That way, you can be sure the whiskers are sending the right messages. Otherwise, they might be telling the Propeller that they detect something even though they didn't, or vice-versa.

In this activity, you will build and test indicator LEDs that will tell you if an object is detected without the help of the Serial Monitor. This is handy if you are not near a PC or laptop, and you need to troubleshoot your IR detector circuits.
A hobby servo is normally used to hold the positions of radio controlled model airplane flaps, boat rudders, and car steering. A micro servo is one of the smallest versions of hobby servos. Hobby servos also come in continuous rotation versions which can be used to drive wheels of rolling robots, but the one in your kit is the standard variety that turns to and holds a position.
In this activity, you will:
