10+
11+
## Python Requirements
12+
13+
1. Create a Python Virtual Environment to install `pip` packages.
14+
15+
```bash
16+
sudo -i
17+
python3 -m venv /opt/EP-0152
18+
source /opt/EP-0152/bin/activate
19+
```
20+
21+
2. Install `pip3` packages:
22+
23+
```bash
24+
pip3 install pillow adafruit_circuitPython_ssd1306
25+
```
26+
27+
- For **Raspbery Pi 5**:
28+
29+
```bash
30+
pip3 uninstall RPI.GPIO
31+
pip3 install rpi-lgpio
32+
```
33+
34+
### Uninstallation of Python VEnv
35+
36+
```bash
37+
sudo rm -rf /opt/EP-0152
38+
```
39+
40+
## Fan Control
41+
I've added [@franganghi](https://github.com/franganghi)'s version of [Raspberry-Pi5-PWM-Fan-Control](https://github.com/franganghi/Raspberry-Pi5-PWM-Fan-Control) as a submodule to this repository.
42+
43+
- Follow the instructions listed in the [README](https://github.com/franganghi/Raspberry-Pi5-PWM-Fan-Control/tree/master?tab=readme-ov-file#raspberry-pi5-pwm-fan-control) to install [as a Linux service](https://github.com/franganghi/Raspberry-Pi5-PWM-Fan-Control/tree/master?tab=readme-ov-file#as-a-service).
