Build your own blinking, buzzing robot and discover the science of sound waves and oscillation with CircuitMess Hertz — a hands-on electronics kit from the Wacky Robots series. Designed for ages 7+, this beginner-friendly build introduces the basics of electronic circuits using real components like LEDs, resistors, and oscillators. Once complete, Hertz flashes with a signature light pattern and doubles as a physical key to unlock a bonus game in the CircuitMess Bit console (sold separately).
