# Pico Explorer Base
# Pico Explorer Base <!-- omit in toc -->
Pico Explorer Base straps a whole host of physical computing goodies to your Pico - a vibrant 1.14" (240x240) IPS LCD screen, four switches, a piezo buzzer/speaker and a DRV8833 motor driver. It also has a bunch of handy accessible general purpose inputs and outputs and a built in breadboard.
[You can buy one here!](https://shop.pimoroni.com/products/pico-explorer-base)
The `picoexplorer` module contains constants you can use with our shared libraries to make it easy to draw to the screen and interface with the buttons, piezo buzzer and motor driver.
The `picoexplorer` module contains constants you can use with our shared libraries to make it easy to draw to the screen and interface with the buttons, piezo buzzer and motor driver. You don't need to use the constants of course, you can skip the `import pico_explorer` and just enter the pin number/s if you prefer. There's a handy reference of what pins are used for which functions on the bottom of the board.

### Motors
Motors are driven by PWM via an onboard DRV8833. We'd recommend using our Motor library to driver them - here's a quick example
Motors are driven by PWM via an onboard DRV8833. We'd recommend using our fully featured Motor library to drive them - here's a quick example:
``` python
import picoexplorer
from motor import Motor
import time
m = Motor(picoexplorer.MOTOR_1)
m.enable()
# run the motor full speed in one direction for 2 seconds
m.speed(1.0)
time.sleep(2)
# and in the opposite direction for 2 seconds
m.speed(-1.0)
time.sleep(2)
m.disable()
```
You can find much more info about working with motors in the [Motor library documentation](https://github.com/pimoroni/pimoroni-pico/tree/main/micropython/modules/motor).
The red LED next to the motor connectors is part of the motor driver circuit - it will light up if the overvoltage/undervoltage/short circuit auto shutdown functions of the motor driver are triggered. It's not user controllable.
#### set_motor
```python
picoexplorer.set_motor(channel, action, speed)
```
Channel should be one of `0` (motor 1) or `1` (motor 2).
Action should be `0` (forwards) or `1` (backwards).
Speed should be given as a number between `0.0` and `1.0`, eg:
```python
picoexplorer.set_motor(0, 0, 0.5) # motor 1 forwards
picoexplorer.set_motor(1, 1, 0.5) # motor 2 backwards
```
And to stop the motor:
```python
picoexplorer.set_motor(0, 0, 0) # motor 1 stop
picoexplorer.set_motor(1, 0, 0) # motor 2 stop
```
### Audio
To make noise with Explorer, you must first select one of the GP0 to GP7 pins to PWM for audio. You'll then need to connect this pin to AUDIO with a jumper wire.
To make noise with Explorer, you must select one of the GP0 to GP7 pins to PWM for audio. You'll then need to connect this pin to AUDIO with a jumper wire.
#### set_audio_pin
To set up the buzzer, first import the `Buzzer` class from the `pimoroni` module and the pin constants from `picoexplorer`:
```python
picoexplorer.set_audio_pin(channel)
``` python
from pimoroni import Buzzer
import picoexplorer
```
`set_audio_pin` configures the PIN that Pico Explorer uses for audio output. It should be one of `GP0` through `GP7`, eg:
Then create a `Buzzer` instance:
```python
picoexplorer.set_audio_pin(0)
``` python
BUZZER = Buzzer(picoexplorer.GP0)
```
This pin must be bridged to the `AUDIO` pin on the Pico Explorer header in order to drive the onboard Piezo.
You can then play audio tones like this - frequency should probably be a number between 1 and 5000 if you have human ears.
#### set_tone
```python
picoexplorer.set_tone(frequency)
```
`set_tone` will play an audio tone out of your chosen audio pin.
```python
frequency = 440
picoexplorer.set_tone(frequency)
``` python
buzzer.set_tone(frequency)
```
To make the buzzer be quiet, you can:
``` python
picoexplorer.set_tone(-1)
buzzer.set_tone(0)
```
### GPIO
The 8 general purpose IO pins on the lower Pico Explorer are GP0 through GP7. You can use `machine` to read a pin in the same way as you would if you were using a Pico on its own.

@ -184,8 +176,40 @@ import machine
GP0 = machine.Pin(0, machine.Pin.IN, machine.Pin.PULL_DOWN)
```
You can also use these pins as outputs, if you wanted to connect up stuff like LEDs:
```python
import machine
GPO = machine.Pin(0, machine.Pin.OUT)
```
Note that if you're connecting external LEDs up to Explorer Base, GP0-7 have built in 100 Ohm resistors, so you don't need to include a resistor in your circuit to protect your LED from drawing too much current.
There's lots more info about how to use `machine` in the [Raspberry Pi documentation](https://www.raspberrypi.org/documentation/rp2040/getting-started/#getting-started-with-micropython).
### Breakout Garden slots / I2C
The slots at the top of the board let you plug (I2C) Breakout Garden breakouts into Pico Explorer.
- [List of Pico-compatible breakouts](https://github.com/pimoroni/pimoroni-pico/blob/main/README.md#breakouts)
Pico Explorer uses GP20 and GP21 for its I2C interface - these pins differ from our default Breakout Garden pins so you will specify you're using a Pico Explorer when running breakout examples. You can use the constants in the shared `pimoroni` module to set up the I2C interface:
``` python
from pimoroni_i2c import PimoroniI2C
from pimoroni import PICO_EXPLORER_I2C_PINS
i2c = PimoroniI2C(**PICO_EXPLORER_I2C_PINS)
```
Alternatively, you can specify the pin numbers directly:
``` python
from pimoroni_i2c import PimoroniI2C
i2c = PimoroniI2C(sda=(20), scl=(21))
```
