I have been working on taking power consumption measurements of the arduino nano control board, as well as the motors and wireless receivers. Unfortunately, Amazon had some problems with delivery and I was unable to receive the current reading board and the motor driver this week. I was planning on...

Motivation – The Arduino IDE can only be used to monitor a single port. Arduino IDE does not allow multiple serial ports to be monitored simultaneously. Serial library can be used to read, write and print to different serial ports. Therefore, different ports can be monitored simultaneously from the...
