Color Count: 4
Package: SMD (Surface Mount Device)Code Examples### Example 1: Basic Usage with ArduinoIn this example, we'll demonstrate how to use the 10 Segments 4 Colors Stripe Digital Bar Graph Display with an Arduino board to display a simple bar graph.```c++
#include <Wire.h>#define BAR_GRAPH_ADDRESS 0x70void setup() {
Wire.begin(); // Initialize I2C communication
}void loop() {
// Set the colors for each segment (Red, Green, Blue, Yellow)
for (int i = 0; i < 10; i++) {
Wire.beginTransmission(BAR_GRAPH_ADDRESS);
Wire.write(0x01); // Select the first segment
Wire.write(0x00); // Red
Wire.write(0x01); // Green
Wire.write(0x02); // Blue
Wire.write(0x03); // Yellow
Wire.endTransmission();
}// Set the value for each segment (0-10)
for (int i = 0; i < 10; i++) {
Wire.beginTransmission(BAR_GRAPH_ADDRESS);
Wire.write(0x02); // Select the segment value register
Wire.write(i); // Set the value (0-10)
Wire.endTransmission();
delay(50); // Update the display
}
}
```### Example 2: Using with Raspberry Pi (Python)In this example, we'll demonstrate how to use the 10 Segments 4 Colors Stripe Digital Bar Graph Display with a Raspberry Pi (using Python) to display a real-time temperature reading.```python
import smbus
import time
import Adafruit_DHT# Initialize the I2C bus
bus = smbus.SMBus(1)# Initialize the DHT11 temperature sensor
dht_sensor = Adafruit_DHT.DHT11
dht_pin = 17# Define the bar graph address and registers
bar_graph_address = 0x70
segment_register = 0x01
value_register = 0x02while True:
# Read the temperature from the DHT11 sensor
humidity, temperature = Adafruit_DHT.read_retry(dht_sensor, dht_pin)# Map the temperature to a segment value (0-10)
segment_value = int((temperature - 20) / 2)# Update the bar graph display
for i in range(10):
bus.write_byte_data(bar_graph_address, segment_register, i)
if i <= segment_value:
bus.write_byte_data(bar_graph_address, value_register, 0x01) # Green
else:
bus.write_byte_data(bar_graph_address, value_register, 0x00) # Offtime.sleep(1) # Update the display every second
```These code examples demonstrate the basic usage of the 10 Segments 4 Colors Stripe Digital Bar Graph Display in various contexts. By following these examples, you can integrate this component into your IoT projects to create engaging and informative graphical displays.
