Inputs are used to get information about what is happening in the real world. For example, you can check if the button is pushed or not by using thedigitalRead()command. Or you can check the temperature in the room by connecting a temperature sensor and using theanalogRead()command. By c...
Open Arduino IDE and create a new file. Afterward, copy the following code into the new file: #define SERIAL Serial #define sensorPin A0 int sensorValue = 0; float tdsValue = 0; float Voltage = 0; void setup() { SERIAL.begin(9600); } void loop() { sensorValue = analogRead(...
Thebaudrate (the symbol is "Bd") is unit we use to describe the "speed" of communication between the two electronic devices. Your computer and the Arduino talk via theUSB/RS-232or similar (serial) interface. There are a few parameters that control this communication, but all of them are...
