The Bestsellers Bundle is best suited for ages 11 and up, since all three kits are hands-on builds. Younger builders can absolutely join in with some adult guidance.
This bundle is packed with a wide variety of skills! You'll learn hands-on electronics by building all three kits, then code them with our visual CircuitBlocks interface: design custom watch faces, explore wireless communication, and mix your own music.
Each kit takes a few hours to assemble, so the bundle gives you three perfect weekend projects. After that, coding and playing with all three devices offers endless fun.
No prior experience with electronics or coding is necessary! All three kits are designed for beginners and come with detailed, step-by-step instructions, and the coding activities are beginner-friendly too.
