In this Arduino Serial example, we will write text to the Arduino serial port, which will send it over the USB cable to your computer, which will then display that text in a terminal window. In the ‘setup()’ function mentioned above, add the following lines to start the Arduino serial...

·Simple Message System- send messages between Arduino and the computer ·SSerial2Mobile- send text messages or emails using a cell phone (via AT commands over software serial) ·TextString- handle strings ·TLC5940- 16 channel 12 bit PWM controller. ...
When the push button is pressed, the Arduino will send a notification to the Raspberry Pi (a simple byte). The Raspberry Pi will then compute a random integer number between 1 and 4, and send it to the Arduino. The Arduino will power on the LED related to this number, and power off...
Serial communications provide an easy and flexible way for your Arduino board to interact with your computer and other devices. This chapter explains how to send and receive information using this capability. Chapter 1 described how to connect the Arduino USB serial port to your computer to upload...
Now, in order to establish the serial communication with the ESP32 over Bluetooth, we will need an additional serial monitor, so we can send the data to the device. Although we can open a new instance of the Arduino IDE and open a new terminal for the Bluetooth emulated COM port, I’...
E-Prime then sent an integer (two bytes) over the serial port to the connected Arduino. As soon as the Arduino received two bytes, it set one of its output lines to HIGH, thereby signaling the external clock connected to this line that it received data. It then waited for 300 ms (...
