+
+Sample code for [DS18B20 Digital Temperature Sensor Module](https://pajenicko.cz/picopad/picopad-modul-s-digitalnim-cidlem-teploty-ds18b20)
+
+- The code imports the necessary modules and sets up the pins for the ST7789 display.
+- Initializes the DS18B20 sensor on the OneWire bus.
+- Runs a loop where it:
+  - Checks for the presence of a DS18B20 sensor.
+  - Reads the temperature from the sensor if found.
+  - Displays the temperature on the screen.
+- Continuously updates the displayed temperature, providing real-time temperature monitoring.

+Sample code for [HC-SR04 Ultrasonic Distance Measuring Module](https://pajenicko.cz/picopad/picopad-modul-ultrazvukoveho-merice-vzdalenosti-hc-sr04)
+
+- The script imports required libraries and configures the pins for the ST7789 display.
+- It initializes the ultrasonic sensor HC-SR04.
+- A function (measure_distance) is defined to measure distance using the ultrasonic sensor.
+- Inside a perpetual loop, it measures the distance using the function and displays it on the screen.
+- If the distance is greater than the sensor's maximum detection range, it waits for a second before the next measurement.
+- The script continuously updates the display with the calculated distance in real time.

+# module_photoresistor.py
+
+Sample code for [GL5516 Light Sensor Module](https://pajenicko.cz/picopad/picopad-modul-svetelneho-senzoru-gl5516)
+
+- The script sets up an ST7789 display and initializes an ADC on pin 26 for a photoresistor.
+- Text is displayed on the screen to label the photoresistor demonstration.
+- Inside an infinite loop, the script continuously reads ADC values from the photoresistor.
+- These ADC values, indicative of light intensity, are then displayed on the screen.
+- If the ADC value is less than 10000, the script clears the old value from the display to prevent ghosting.
+- The script sleeps for 100ms after each read-display cycle to ensure smoother updates of the display.
