GROVE Pressure Sensor BME280 on Normal LCD1602 I2C Display In a previous tutorial WE have seen the Grove Beginner Kit for Arduino from SEEEDSTUDIO https://gustmees.wordpress.com/2020/08/03/grove-beginner-kit-for-arduino-seeedstudio-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/, and THE BREAKOUT to use the different modules with OWN Code examples. WE were ALSO using the OLED module as a BREAKOUT in this tutorial https://gustmees.wordpress.com/2020/10/21/grove-beginner-kit-for-arduino-seeedstudio-the-breakout-temperature-humidity-on-oled-display-first-steps-with-the-arduino-uno-r3-and-nano-maker-makered-maker-spaces-coding/ In this tutorial WE will…

Well, I made some searches on the internet and I found the right answer on a forum about this error, which says that one should scan the I2C Address of the device and replace the “lcd.init();” by “lcd.begin (0x3F,16,2);” whereby “0x3F” is the I2C Address of my LCD1602/I2C module. I scanned to find out the I2C Addess with this sketch, please check here:

How-To transform an LCD1602 SPI Sketch to an LCD1602 I2C Sketch We were already playing around, as seen on my tutorials below, with the Temperature/Humidity sensors DHT11, DHT22 and LCD1602, without I2C possibility. There were a lot of cables to connect, we will try out this time to use a LCD with I2C bus connection as it…
