+# Basic UART communications between OpenMV and Arduino Uno.
+
+# 1) Wire up your OpenMV Cam to your Arduino Uno like this:
+#
+# OpenMV Cam Ground Pin   ----> Arduino Ground
+# OpenMV Cam UART3_TX(P4) ----> Arduino Uno UART_RX(0)
+# OpenMV Cam UART3_RX(P5) ----> Arduino Uno UART_TX(1)
+
+# 2) Uncomment and upload the following sketch to Arduino:
+#
+# void setup() {
+#   // put your setup code here, to run once:
+#   Serial.begin(19200);
+# }
+#
+# void loop() {
+#   // put your main code here, to run repeatedly:
+#   if (Serial.available()) {
+#     // Read the most recent byte
+#     byte byteRead = Serial.read();
+#     // ECHO the value that was read
+#     Serial.write(byteRead);
+#   }
+# }
+
+# 3) Run the following script in OpenMV IDE:
+
+import time
+from pyb import UART
+
+# UART 3, and baudrate.
+uart = UART(3, 19200, timeout_char=200)
+
+while True:
+    uart.write("Hello World!\n")
+    if uart.any():
+        print(uart.read())
+    time.sleep_ms(1000)
