Say it to PAL

“Read the light sensor plugged into socket A0.”

The code PAL writes

const v = await p.read('grove-base-hat-zero', 'a0_voltage');
p.log('A0: ' + v.toFixed(3) + ' V');

When to pick it

Use when an analog Grove sensor (light, sound, rotary angle, soil moisture) is plugged into the Base Hat's analog sockets on a Raspberry Pi.

Good to know

3.3 V only: 5 V Grove modules are out of spec on this Hat.
Socket A0 carries channels 0 and 1; the sensor's signal is on the even channel.

About it

The Grove Base Hat for Raspberry Pi Zero brings Grove sockets to the Pi's GPIO header: I2C sockets wired straight to the Pi's I2C bus, digital and PWM sockets on GPIO pins, a UART socket, and analog sockets. The Pi has no analog inputs, so the Hat carries a small microcontroller that measures 6 analog channels with 12-bit resolution and answers over I2C. Each channel is available as a raw count, a voltage and a ratio of the supply. The Hat runs at 3.3 V only; 5 V Grove modules are out of spec on it.
