 \begin{frame}{What is I2C?}
   \begin{itemize}
   \item A very commonly used low-speed bus to connect on-board
-    devices to the processor.
+    and external devices to the processor.
   \item Uses only two wires: SDA for the data, SCL for the clock.
   \item It is a master/slave bus: only the master can initiate
     transactions, and slaves can only reply to transactions initiated
