## Displaying wind readings on an oled display
### Connecting the oled display to the Pico W
I used the following tiny [oled display](https://www.amazon.com/Self-Luminous-Display-Compatible-Arduino-Raspberry/dp/B09JWN8K99/?th=1) in the fab inventory to display the wind sensor readings from an anemometer.
Using I2C protocol to connect the oled display to the Pico W, I connected the following pins:
| Pico W | OLED Display |
| --- | --- |
| 16 | SCL |
| 17 | SDA |
| 3V3 | VCC |
| GND | GND |
### Displaying the wind readings on the oled display
I used the ssd1306 library and I2C interface in micropython to display the wind readings on the oled display. I copied the following [ssd1306.py](https://github.com/stlehmann/micropython-ssd1306/blob/master/ssd1306.py) and loaded the code on the micropython device. And the micropython code for displaying to the wind sensor readings is just a few lines of code:
```
from time import sleep
import utime
from machine import ADC, Pin, I2C
import ssd1306
i2c = I2C(0, sda=Pin(16), scl=Pin(17))
display = ssd1306.SSD1306_I2C(128, 64, i2c)
wind = ADC(Pin(28))
while True:
display.fill(0)
digital_value = wind.read_u16()
print("ADC value =", digital_value)
voltage_value = 3.3 * (digital_value/65536)
print("Voltage: {}V".format(voltage_value))
degrees = (voltage_value/3.1) * 360
print("Wind degree: {} degrees".format(degrees))
display.text('Wind direction', 0, 0)
display.text('{} degrees'.format(int(degrees)), 0, 16)
display.show()
sleep(0.1)
```

As noted in input devices, I would like to add a GPS module as additional input and mill the final PCB for the final project.
