In this article we’ll see how to use the common LCD1602 display, how to connect to it both discreetly and using I2C. It stores the program inside its drive and can continuously run the program again after being powered. Liquid Crystal Displays or LCDs are an inexpensive and versatile way of adding display capabilities to your Arduino projects. You can disconnect the Arduino UNO from your computer and power it using a 5V DC power adaptor connecting to its 2.1mm power jack. It keeps calling the draw function to display the text and data every time the sensor is refreshed. The loop function of the Arduino board is the main function. So I also included a "setRot180" function to rotate the display. According to my circuit, my screen was upside down.
Then call the begin function for the sensor.

To set up the hardware, give the serial port a 10 seconds delay. The print function can directly show the text and numbers. Measure, monitor, store months of data and send it to your server. You can adjust the position by changing the number in the "setPrintPos" function. The affordable, stable, easy to build and tested in the wild open source weather station. Print out the humidity and temperature using the print function in the "u8glib" file. In the function "draw", get the data from the serial data port and put them into to float numbers using the "readHumidity" and "readTemperature" functions. This ensures the data will be refreshed frequently. So there is a "delay(2000)" inside the loop function. Because the frequency of data transmission is roughly 1 reading every 2 seconds (which is 0.5 Hz), when programmed in Arduino IDE, we need to set the delay inside the loop function to be more than 2 seconds. Because the sensor library requires the data to declare the object.Īnd you can test the sensor's data by monitoring the output data through digital pin 2 by using the function called "Serial.print()". 136 weather projects Solar Charged Battery Powered Arduino Uno Using DHT11 Personal Weather Station (Arduino+ ESP8266 +.
