Adafruit has today announced the availability of its new Circuit Playground Express for 4-H which is now available to purchase priced at $24.95. The 4-H themed development board has been created in a special green colour and finished with the 4-H emblem on the back, to celebrate the “positive youth development and mentoring organisation”.
“Circuit Playground Express is the next step towards a perfect introduction to electronics and programming. We’ve taken the original Circuit Playground Classic and made it even better! Not only did we pack even more sensors in, we also made it even easier to program. This version works just like any other Circuit Playground Express, and is great for sensor projects like this soil sensor. Turn it into an alarm, so it beeps when a door is opened, or plot light and temperature in your garden to track your plants as they grow up. There’s hundreds of projects to build, learn and adapt.”
