The Explorer HAT and Explorer pHAT have a heap of useful input and output options that will take your Raspberry Pi projects to the next level. Great for driving motors, using analog sensors, interfacing with 5V systems, and touch interfaces.
## Installing
### Full install (recommended):
We've created an easy installation script that will install all pre-requisites and get your Explorer HAT/pHAT
up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal
on your Raspberry Pi desktop, as illustrated below:
In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:
```bash
curl https://get.pimoroni.com/explorerhat | bash
```
### Manual install:
Enable i2c:
```bash
sudo raspi-config nonint do_i2c 0
```
Install the library:
```bash
python3 -m pip install --upgrade explorerhat
```
### Development:
If you want to contribute, or need to run the latest, unreleased code you should clone this repository, `cd` to the library directory, and run:
```bash
sudo python3 setup.py install
```
You will also need to enable the i2c bus:
```bash
sudo raspi-config nonint do_i2c 0
```

## Important Notes
Explorer HAT/pHAT uses an output driver chip called the ULN2003A, which contains a set of transistor pairs called a Darlington Array. It transforms the small logic signal of the Pi into something capable of driving much bigger loads, such as motors, steppers, lights and more.
The 4 outputs on Explorer can sink 5V, but not source. This means you need to connect your load to one of the 5V pins, and then to the output. When you turn the output on it will connect your circuit to ground, allowing current to flow and your load to turn on. This is the opposite of using a bare Pi GPIO pin, where you might connect to the pin and then to ground; keep this in mind!
