We’ve been working with LCD displays, for a long time so we thought we’d show you how to hook up a CFA533 I2C LCD with a Keypad to an Arduino. Giving you the ability to output and control your arduino via I2C. Continue reading Connect Arduino to Crystalfontz CFA533 with I2C
Stepper motors fall somewhere in between a regular DC motor and a servo motor. They have the advantage that they can be positioned accurately, moved forward or backwards one ‘step’ at a time, but they can also rotate continuously.
In this lesson you will learn how to control a stepper motor using your Arduino and the same L293D motor control chip that you used with the DC motor in lesson 15.
