We have a laser distance meter and want to read the distance from it.
In the manual it states:
“connect the LCD to the device, the measured distance is sent as ASCII string, which is understood by External Displays with a serial interface.”
There is a simple diagram with a Rx Tx and ground connection between the LCD and device.
I hope that I can plug these Rx and Tx into the arduino’s Tx and Rx and read the value? This is the part I need help with. Is there a function/command to read the ASCII from the Rx pin of the arduino?
I have made a logger with a RTC and SD card and want to log the readings.
Hope I’ve asked this in the right part of the forums.
Help is much appreciated
