Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.
Power the clock module from 3V3, not 5V: its pull-ups would put 5V on the ESP32's I2C pins.
Strictly follow the description given with this video.
