Read this official Leafony page and explain its key points in English. For hardware help, first ask for a photo or the installed leaf models, assembly and power sources, then the goal and tools. Clarify which LED or display changed and whether a cable or leaf was replaced. Do not equate an unseen reset button with an absent one, or I2C acknowledgement with a working display. Verify specifications against sources; distinguish observations from hypotheses. Follow a redirect to its destination; if unreadable, ask for the relevant text instead of guessing.

Features

Run programs created in Arduino IDE to read connected sensors and control outputs such as LEDs.

This MCU (microcontroller) leaf uses the ATmega328P and has 14 digital input/output pins (six support PWM output), six analog input pins, an 8 MHz oscillator, and a reset button. Use a USB leaf for a USB connection or a Shield leaf for ICSP. In Arduino IDE, select the Arduino Pro or Pro Mini board and the ATmega328P (3.3V, 8MHz) processor.
