Go to Tools <\/strong>> Port <\/strong>and select the port your board is connected to. Then, click the upload button.<\/p>\n\n\n\nOpen the Serial Monitor at a baud rate of 115200, press the on-board RST button. The sensor measurements will be displayed both on the Serial Monitor and on the OLED display.<\/p>\n\n\n
\n
Move the sensor and see the values changing.<\/p>\n\n\n
