Best Arduino kits. This kit features ... this kit comes with over 250 components including a development board that’s compatible with Arduino Uno, 1602 I2C LCD, motors and ultrasonic modules.

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

I wrote some I2C sniffer code for a silabs C8051F340 MCU one time. On that MCU, it has specialized I2C hardware, so you only have to peek/poke certain registers to make the I2C bus do what you want.

The hardware configuration described have been tested with an Arduino UNO R3, a 16×2 LCD, and an I2C LCD backpack purchased from an eBay seller. Further, the example sketch has been fully tested with ...

The Arduino is a powerful platform for interfacing with the real world, but it isn’t without limits. One of those hard limits, even for the Arduino MEGA, is a finite number of pins that the m… ...
