The following sketch shows how to get a single character from the Serial Monitor window and determine if the character is a number or not. Here, we can use the staticvariable as a reference, as we know it is always 500. Opening the Serial Plotter If you choose the potentiometer example sketch, when turning the knob, you should be creating a 'wave-like' pattern in the plotter. ensure that the serial plotter is also set to 115200. Click the button in the the top right of the IDE window to open the Serial Plotter. The X axis has 500 points and each tick of the axis is equal to an executed. Let's now look at how to handle both serial input and output. Learn to interface MPU6050 with Arduino, Accelerometer & Gyroscope working, pinout, wiring. The vertical Y axis adjusts as the value of your serial data increases or decreases. It was used to display the results or outputs from various example sketches in each part of the course. As you turn the pot, the values will change, corresponding to the voltage coming into pin A0.
Any serial program, or even a custom serial application can be used to send data to the Arduino instead of using the Serial Monitor window.Įxcept for part 13 of this course, the Serial Monitor window has only been used for output purposes. Now, when you open your Serial Monitor in the Arduino IDE (by clicking on the icon on the right side of the top green bar or pressing Ctrl+Shift+M), you should see a steady stream of numbers ranging from 0.0 - 5.0. A user can enter data in the input field in the serial monitor window to send values and data to the Arduino.
