,Light ‘Em Up,g outputs from the Arduino as well as simple inputs such as button presses. On the hardware side, you will learn about LEDs, buttons, and resistors, including pull-up and pull-down resistors, which are important in ensuring that input devices are read correctly. Along the way, you will pick up the c

Simple Sounders and Sensors, add alarms, warning beeps, and alert notifications to the device we are creating. Since version 0018 of the Arduino IDE, a new command has been added that allowed tones to be created easily. We will also find out how to use the piezo as a sensor and learn how to read data from it. Finally, we will

Driving a DC Motor,ls you are about to learn will be essential. Driving a motor requires currents higher than the Arduino can safely provide from its outputs, so we will need to make use of transistors and diodes to ensure that we have enough current for the motor and diodes for protection of the Arduino.

Binary Counters and Shift Register I/O,e a fantastic little chip known as a shift register. These ICs (integrated circuits) will enable us to control eight separate LEDs using just three pins from the Arduino and, as you will see in Project 18, a total of 16 LEDs, again using just three pins from the Arduino.

Servos, of the motor. Servos typically rotate through 180 degrees, although you can also buy continuous rotation servos or even modify a standard one for continuous rotation. If you have ever owned a radio-controlled (RC) airplane, you have come across servos; they are used to control the flight surfaces.

Pressure Sensors, is easily interfaced with an Arduino and provides accurate pressure and temperature readings. The device needs to be connected to the Arduino’s I2C (inter-integrated circuit or I-Squared-C, also known as a two-wire interface (TWI)) bus for data to be exchanged. I2C is a new concept for you, and alt
