I am using an Arduino Uno and I am trying to hook up a Camera to the RX and TX input/output. In the code for testing the camera, they use Serial1.begin(). Does the arduino uno not support a second serial port. If so, how could I hook this camera up and get it working? This is the website I am referring to about the camera: Overview | TTL Serial Camera | Adafruit Learning System
Thanks for your time in advance!
