Hi @Valencia_Maker_Lab! I am run the science and engineering labs at a community college, and have been introducing littleBits to our physics and engineering profs, with an eye toward incorporating them into the lab activities for their students. So far, the oscillators from the Synth kit are the most popular (but I hear the question "why is there no sine wave" a lot. I tell them it's because musically, sine wave sounds are boring.)
But I also see a lot of potential in the number bit, the power bit and the slide dimmer. When making circuits (with discrete components, like resistor networks in physics, or feedback circuits in engineering) it is especially nice to insert number bits to continuously monitor voltages. The slide dimmer is an easy tool to adjust the voltage, and the power bits are a very convenient source of 5.00 volts.
I could use proto modules to connect these to the circuitry, but they are cumbersome to use, so I have made connectors by cutting a wire bit in half, and soldering pins to the bare leads. Those are then very quick to connect, disconnect, and change positions. Here is an example of how I use them.
Good luck with your workshop! Please be sure to report back here afterward, so we can 'debrief' you on how it all worked. I want to be ready for the Fall semester to go full STE(A)M ahead!
