+====== Enkoodri näidis ======
+Enkooder peab olema ühendatud anduri mooduliga. Enkoodril on kaks 3,5 mm pistikut, mis peavad olema ühendatud anduri mooduli 3,5 mm sisendpesadega. Kontrolleri ja anduri moodulid peavad olema omavahel ühendatud.
+{{:en:iot:examples:encoderpicture1.jpg?200|}}
+Pistikud peavad olema õigesti ühendatud: nelja kanaliga sisend (D) pesasse (parempoolne) ning kolme kanaliga sisend (A) pesasse (vasakpoolne).

+Vajaminevad teegid:
+<code>lib_deps = ITTIoT, ClickEncoder</code>
+Näidiskood prindib välja ja saadab serverile info enkoodri praeguse asendi väärtuse. Väärtus suureneb enkoodri ratast üht pidi pöörates ning väheneb teist pidi pöörates. Lisaks sellele on enkoodri rattal lüliti, mis aktiveerub alla vajutades. Lülitit vajutades saadetakse info lüliti vajutamise kohta jada- ehk serial porti.
