Good day, everyone
I am currently new in arduino and I am developing a project where I used NPK Sensor to communicate with my Wemos D1 R1 with the use of RS485. The problem is I've tried a lot things to connect my RS485 RE and DE, and RO and D1 to Wemos D1 R1 but I still receive none and error. the RO and DI should be connected to RX and TX, meanwhile the RE and DE should be connected to any Digital Pins. A little help would be much appreciated.
Thank you!
