On the [Maker.io](http://Maker.io) page about protecting analog inputs with a zener diode, the “connect the zener diode” section is backwards, as zener diodes must be connected in reverse - the anode should be connected to “ground” and the cathode to the input pin. Here is the link and the incorrect info:

> **[How to use a Zener diode to protect ADC/MCU analog inputs](https://www.digikey.com/en/maker/tutorials/2024/how-to-use-a-zener-diode-to-protect-adc-mcu-analog-inputs)**
>
> Safeguard your ADC/MCU analog inputs with Zener Diodes. Step-by-step instructions on implementing Zener diode protection for your electronic projects.

" **2. Connect the Zener Diode:**

- Connect the anode of the Zener diode to the analog input pin on the MCU or ADC.
- Connect the cathode of the Zener diode to ground (GND)."
