+\section{Connect the nunchuk}
+Take the nunchuk device provided by your instructor.
+We will connect it to the second I2C port of the CPU (\code{i2c1}),
+with pins available on the \code{P9} connector.
+Identify the 4 pins of the nunchuk connector:
+Connect the nunchuk pins:
+\item The \code{GND} pin to P9 pins 1 or 2 (\code{GND})
+\item The \code{PWR} pin to P9 pins 3 or 4 (\code{DC_3.3V})
+\item The \code{CLK} pin to P9 pin 17 (\code{I2C1_SCL})
+\item The \code{DATA} pin to P9 pin 18 (\code{I2C1_SDA})
 \section{Test the Nunchuk}
 Copy the newly generated kernel and device tree images into the first SD card
