     Project: ArrayLimits
 
-//------------------------------------
-// Tera Term configurations
-// Terminal - New-line, Receive LF, Transmit LF
-// Serial port - Data 8 bit, Parity none, Stop 1 bit data, Flow control none.
-// Baud as specified below.
-//------------------------------------
-
-// Serial pc(SERIAL_TX, SERIAL_RX, 921600); // Highest Tera Term speed - works.
-// Serial pc(USBTX, USBRX, 115200); // Highest common speed - works.
-// Serial pc(USBTX, USBRX); // Default 9600 baud, alternate pin names - works.
+    Demonstrates abuse of array limits on Nucleo boards.
+    
+    If necessary, avoid this with code like:
+    
+    if (index > SIZE - 1) {
+        index = SIZE - 1;
+    } else if (index < 0) {
+        index = 0;
+    }
+    Use index...
