Ciao! Energia @ Maker Faire Rome 2014!

Energia was at Maker Faire Rome this past week. It was a great opportunity to meet with makers in the beautiful Italian city!

The Energia team was at the Texas Instruments booth showcasing demos based on the LaunchPad platform. Below are some videos that showcase a few of the demos that we had at the Texas Instruments booth!

DEMO 1: Wireless (SubGHz RF ) flower pot moisture sensor

In this demo, we created a simple wireless flower pot moisture sensor. We used an 8×8 LED matrix to visualize a happy face or sad face depending on the presence of water. We are able to remotely monitor a flower pot thanks the SubGHz RF BoosterPack, which allows us to send sensor data wirelessly.

Hardware (Energia libraries available for each component)

  • Olimex 8×8 LED Matrix BoosterPack
  • 2x CC110L SubGHz RF BoosterPack (430BOOST-CC110L)
  • 2x MSP430F5529 LaunchPad (MSP-EXP430F5529LP)
  • 1x Grove Moisture Sensor from SeeedStudio

DEMO 2: Twitter-enabled scrolling marquee

In this demo, we have several 8×8 LED matrices daisy-chained together to create a simple digital sign. The LED matrices are hooked up to the MSP430F5529 LaunchPad & CC3100 WiFi BoosterPack. The LaunchPad is connected to a cloud-side application over WiFi. The cloud-side application is listening to all public tweets for the hashtag #LaunchPad. If a tweet with #LaunchPad is found, the twitter message is published to the LaunchPad over MQTT. The LaunchPad receives the string and ultimately scrolls it through the 8×8 LED matrices.


  • MSP430F5529 LaunchPad
  • CC3100 WiFi LaunchPad
  • Several 8×8 LED matrices

DEMO 3: Publishing sensor data to the cloud with MQTT to visualize data on

In this demo, we are publishing potentiometer sensor data to a cool cloud-side visualization tool called In this demo, we are publishing our sensor data to the cloud using MQTT.
