+# Program: Send Strings to an Arduino From a Raspberry Pi
+# File: send_strings_to_arduino.py
+# Description: This program runs on a Raspberry Pi. It sends strings
+#   to Arduino. It also receives the  string it sent
+#   and prints it to the screen. This provides bi-directional (2-way) communication
+#   between Arduino and Raspberry Pi.
