![]() ![]() I2C is a serial communication standard which uses Master Slave system. Arduino USART can only communicate with one device, SPI(Serial Peripheral Interface) can be used to communicate upto 3 devices but I2C can be used to communicate hundreds of devices. Example of such I2C capable system are LCD, EEPROM, different types of sensors such as temperature sensor, pressure sensors, accelerometers and others. ![]() ![]() I2C serial communication is designed to connect number of integrated circuit which is cable of I2C communication. If two devices of different system like two Arduino are used for I2C communication another wire which is the ground wire is required. It is also called Two Wire Interface (shortened to TWI) because it uses two wire when the two I2C devices are within the same system. I2C is acronym for Inter-Integrated Circuit which is a serial communication standard developed by Philips Semiconductor in 1982. ![]() One Arduino is configured as a master and the other is configured as slave. Hence it is useful if I/O capability is to be increased or if more processing is required. This is useful if we want to transfer data from one Arduino to another or control sensors or actuator connected to one Arduino with another Arduino. uint16_t noResult = įor(int i = 15 i <= resultToTimingInfo(&results).In this tutorial we will show how two Arduino can be communicated using I2C communication protocol. Here I enable the receiver and the sender of ir signals. Here I put in all the needed libraries and some variables that I'll be needing in my code I'll now discuss the code that I've written #include My idea was to first 'catch' the signal using the ir receiver, this doesn't cause any problems, but just to be sure, this is the general signal that it receives: This is my setup, the only difference is that the input pin for the ir led is 17 and that I'm not using a resistance in my circuit. I'm using an esp32 with a library to use the Arduino IDE. I have close to none experience using this library, so any help would be great! Hello fellow humans (: I've been stuck for 4 days on capturing and sending a raw infrared signal. ![]()
