I2C_LCD is an easy-to-use display module, It can make display easier. Using it can reduce the difficulty of make, so that makers can focus on the core of the work. We developed the Arduino library for I2C_LCD, user just need a few lines of the code can achieve complex graphics and...
Arduino I2C master library A better I2C master library, originally by Wayne Truchsess. Seehttp://dsscircuits.com/index.php/articles/66-arduino-i2c-master-library On most Arduino boards, SDA (data line) is on analog input pin 4, and SCL (clock line) is on analog input pin 5. On the ...
