Students create projects that introduce them to Arduino—a small device that can be easily programmed to control and monitor a variety of external devices like LEDs and sensors. First they learn a few simple programming structures and commands to blink LEDs. Then they are given three challenges—to modify an LED blinking rate until it cannot be seen, to replicate a heartbeat pattern and to send Morse code messages. This activity prepares students to create more involved multiple-LED patterns in the Part 2 companion activity.

The student will watch a brief video about the first Morse Code ever sent and how it impacted American communications, even today. Students will be able to decipher a short Morse Code code (SOS). They will also learn about Kryptos, an artwork that contains four secretive messages and is placed on display outside of the CIA headquarters.

Students learn about electrical connections, how they work and their pervasiveness in our world. They consider the usefulness of wireless electrical connections for connecting electrical devices. Morse code is introduced as a communication method that takes advantage of on/off states to transmit messages by electrical bursts sent via wires, light or sound. They learn the Morse code rules and translate a few phrases into Morse code. Specifically, they learn about a wireless connection type known as Bluetooth that can be used to control LEGO robots remotely from Android devices, which leads into the associated activity.
