The blue potentiometer on the I2C LCD1602 (see the figure below) is used to adjust the backlight for better display. What I envisioned is a state-machine that would perform work on transitions of either SCL or SDA – or so I thought. In this demo code, Arduino sends stepper-control command to I2C motor driver via I2C bus, with SteperStepset() to set the step number, and StepperMotorEnable() to set the direction and speed. This will be accomplished by making an I2C controller for an HC-SR04 sensor out of an ATtiny85 (or ATtiny45). It was invented by Philips in 1980’s, originally to provide easy on-board communications between a CPU and various peripheral chips in a TV set. I2C Communication The I2C protocol involves using two lines to send and receive data: • a serial clock pin (SCL) that the Arduino pulses at a regular interval, • a serial data pin (SDA) over which data is sent between the two devices. I2C) interface as well. Grinan explains how I2C works, provides many useful links to information related to I2C and example Arduino code for a robot project where multiple Arduino boards are used for sensing and control. In this first of several tutorials we are going to investigate the I2C data bus, and how we can control devices using it with our Arduino systems. I2C protocol is added in the device that is mainly two-wire protocol used to connect low-speed devices like ADC and DAC converters, I/O interfaces and microcontrollers. Grinan submitted this article to uCHobby as part of the uCHobby Giveaway program. ConfigurableFirmata This library implements the Firmata protocol as a set of plugins that can be used to create applications to remotely interface with an Arduino board. Both programs do not require any external libraries or hidden code and I believe more flexible. Data can flow in any direction on the I2C bus, but when it flows is controlled by the master device.
