MAKEVMA101

The MAKEVMA101 (Arduino® compatible) Mega 2560 is a microcontroller board based on the ATmega2560. It
has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analogue inputs, 4 UARTs
(hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a
reset button. It contains everything needed to support the microcontroller. Connect it to a computer with a
USB cable or power it with an AC-to-DC adapter or battery to get started. The Mega is compatible with most
shields designed for the Arduino® Duemilanove or Diecimila.

4. What is Arduino

Arduino® is an open-source prototyping platform based in easy-to-use hardware and software. Arduino® boards
are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output
– activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by
sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming
language (based on Wiring) and the Arduino® software IDE (based on Processing).

7. Operation

7.1 The Breadboard

Breadboards are one of the most fundamental pieces when learning how to build circuits. In this tutorial, we
will introduce you to what breadboards are and how they work.

Let us look at a larger, more typical breadboard. Aside from the horizontal rows, breadboards have what are
called power rails that run vertically along the sides.

Ravine.

Chips have legs that come out of both sides and fit perfectly over the ravine. Since each leg on the IC is
unique, we do not want both sides to be connected to each other. That is where the separation in the middle of
the board comes in handy. Thus, we can connect components to each side of the IC without interfering with the
functionality of the leg on the opposite side.

7.2 A Blinking LED

Let’s start with a simple experiment. We are going to connect an LED to one of the digital pins rather than
using LED13, which is soldered to the board.

Required Hardware

 1 x red M5 LED
 1 x 220 Ω resistor
 1 x breadboard
 jumper wires as needed

Follow the diagram below. We are using digital pin 10, and connecting the LED to a 220 Ω resistor to avoid
high-current damaging the LED.

Result

After programming, you will see the LED connected to pin 10 blinking, with an interval of approximately one
second. Congratulations, the experiment is now successfully completed!
