. . 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 […]
