Arduino Serial In

by



To make a Serial connection you can also use plain wires between the Raspberry Pi GPIOs and the Arduino pins. Depending on your Arduino board you might need to use a voltage level-shifter. The Raspberry Pi is operating at 3.3V. For Arduino boards like Due, 101, it. The Arduino IDE has a feature that can be a great help in debugging sketches or controlling Arduino from your computer's keyboard. The Serial Monitor is a separate pop-up window that acts as a separate terminal that communicates by receiving and sending Serial Data. See the icon on the far right of the image above. I started with an easy example. Serial.available & serial.read from arduino tutorial. I managed to use the serial.read. But only for one figure number. How i'm gonna read the serial reply from the reader. The reply is AA BB 06 00 BF FF 01 01 00 40. Serial monitor of Arduino is a very useful feature.Serial monitor is used to see receive data, send data,print data and so on.Serial monitor is connected to the Arduino through serial communication. This serial communication occurs using RX (pin 0) and TX (pin 1) terminal of Arduino. Any kind of data can send through this serial monitor.

About this project

Arduino

The analog input is read and the result is printed in the Serial Monitor. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value is 0. When the shaft is turned all the way in the opposite direction, there are 5 volts going to the pin and the input value is 1023. In between, analogRead() returns a number between 0 and 1023 that is proportional to the amount of voltage being applied to the pin.
