Write code in MicroPython to display temperature reading from internal sensor in celsius and fahrenheit on a SSD1306 display every second. Raspberry Pi Pico board.

Open THONNY IDE copy code from ChatGPT

main.py

import machine

import ssd1306

import utime

# Initialize the I2C bus and the SSD1306 display

i2c = machine.I2C(0, sda=machine.Pin(8), scl=machine.Pin(9), freq=400000)

oled = ssd1306.SSD1306_I2C(128, 32, i2c)

# Define a function to convert Celsius to Fahrenheit

def c_to_f(celsius):

    return (celsius * 1.8) + 32

while True:

    # Read the temperature from the internal sensor

    temp_celsius = machine.ADC(4).read_u16() * 3.3 / 65535 * 100 - 50

    temp_fahrenheit = c_to_f(temp_celsius)

    

    # Clear the display and print the temperature readings

    oled.fill(0)

    oled.text("Temp (C): {:.1f}".format(temp_celsius), 0, 0)

    oled.text("Temp (F): {:.1f}".format(temp_fahrenheit), 0, 10)

    oled.show()

    

    # Wait for 1 second before reading the temperature again

    utime.sleep(1)

ChatGPT explaines the code:

MicroPython code that reads the temperature from the internal sensor and displays it on an SSD1306 OLED display. The code uses the ADC (Analog-to-Digital Converter) to read the temperature and converts it from Celsius to Fahrenheit using the c_to_f function. The temperature readings are then displayed on the OLED display using the oled.text method.

The main loop of the code continuously reads the temperature and updates the display every second using the utime.sleep function.

Here's a step-by-step breakdown of what the code does:

1. Import the necessary modules:

import machine

import ssd1306

import utime

2. Initialize the I2C bus and the SSD1306 display:

i2c = machine.I2C(0, sda=machine.Pin(8), scl=machine.Pin(9), freq=400000)

oled = ssd1306.SSD1306_I2C(128, 32, i2c)

3. Define a function to convert Celsius to Fahrenheit:

def c_to_f(celsius):

    return (celsius * 1.8) + 32

4. Enter the main loop:

while True:

5. Read the temperature from the internal sensor using the ADC:

 temp_celsius = machine.ADC(4).read_u16() * 3.3 / 65535 * 100 - 50

6. Convert the temperature from Celsius to Fahrenheit using the c_to_f function:

 temp_fahrenheit = c_to_f(temp_celsius)

7. Clear the OLED display using the oled.fill method:

oled.fill(0)

8. Print the temperature readings on the OLED display using the oled.text method:

oled.text("Temp (C): {:.1f}".format(temp_celsius), 0, 0)

    oled.text("Temp (F): {:.1f}".format(temp_fahrenheit), 0, 10)

9. Update the OLED display using the oled.show method:

oled.show()

10. Wait for 1 second before reading the temperature again using the utime.sleep function:

utime.sleep(1)
