-
• POWER (blue bit) is needed in every circuit and is the start of all your students’ creations.
-
• INPUT (pink bit) modules add control to the circuit, through information provided from your students and/or the environment, and send signals to the modules that follow.
-
• OUTPUT (green bit) modules complete an action or a task (for example, light, buzz, or move). These are the modules that “do something.”
-
• WIRE (orange bit) modules expand the circuit’s reach and change direction. Students use the wire modules to help place modules exactly where they want, especially if they are embedding inside a structure. Some orange modules also add a level of complexity and programmability to the circuit.
