This project will test your Arduino by blinking an LED that is connected directly to the board. This project is identical to project 1 except that we will be building it on a breadboard.
Once complete, the LED should turn on for a second and then off for a second in a loop. Using a potentiometer, you will be able to control the resistance of an LED. Turning the knob will increase and decrease the frequency the LED blinks. This project will blink 6 LEDs, one at a time, in a back and forth formation. This type of circuit was made famous by the show Knight Rider which featured a car with looping LEDs. Using a potentiometer, you can control a series of LEDs in a row.
Turning the potentiometer knob will turn on or off more of the LEDs. A photoresistor changes the resistance a circuit gets based on the amount of light that hits the sensor.
In this project, the brightness of the LED will increase and decrease based on the amount of light present. A temperature sensor measures ambient temperatures of the world around it. In this project, we will be displaying the temperature in the serial monitor of the Arduino IDE. In this project, you will be able to sweep a servo back and forth through its full range of motion.
Using a switching transistor, we will be able to control a DC motor. If everything is connected correctly, you should see the motor spinning. An LCD is a liquid crystal display that is able to display text on its screen. The potentiometer is used to adjust the contrast of the display. We truly believe that adding a makerspace to a school or library can help students acquire the skills needed for the 21st century.
Copyright Makerspaces. Getting Started Before you can start working with Arduino, you need to make sure you have the IDE software installed on your computer. Select Serial Port Next, you have to tell the Arduino which port you are using on your computer. I've been an electronics hobbyist for years but mainly dealt with analog world with minimal interest in too much on the digital side. I did programming but never with a microprocessor until I got my Arduino last summer. Now I'm hooked.
Unfortunately, the usual books for "helping" with Arduino give sketches and explain bits and pieces without ever doing an overview of the system. However, this book is fantastic. Just got it today and have read over half of it; I've marked it up with pen to remind myself of crucial facts that I wish I had known a few months back. Thankfully, this book assumes no knowledge of C language and holds your hand through the process. It does a wonderful job explaining what each section of the programming does, it explains the hardware of the board, and it explains how the board communicates with the computer.
At long last, instead of just copying and pasting someone else's program and hoping I can modify it to work for my own purposes, I can understand WHY certain things work the way they do. I have used it so much that I've about worn it out. Yes, the info that is in the book can be found elsewhere, but he covers so much material so well in such logical places. I have used this book so much in referring to things that I may have to order a second copy as insurance in case I misplace the first.
To be such a small book, it packs a lot of punch. It's written at just the right level for beginners who are just learning about Arduino and microprocessors in general, and he points you to all the resources on the web for further information. The book is practical and useful and just plain fun to read. So instead of having to copy and paste everyone else's code all the time, read this book to understand at least the basics of WHY things work in an Arduino the way they do.
Good for beginners but could be a little more detailed By Tom Servo I am experienced with microcontroller systems but new to Arduino. I found this disappointing as timer interrupts are a common way to handle "background" tasks this is where you can run code at specific time intervals. One could argue that this is not a beginner topic but since pin interrupt-on-change interrupts ARE discussed I think timer interrupts should have been as well.
This is briefly mentioned in Chapter 1, but the author just mentions to be careful to not exceed the 40mA current limitation. This should have been repeated in Chapter 6 which deals with digital interfacing. One of the most common mistakes in interfacing is overlooking the max operating specifications and damaging the chip or decreasing long-term reliability.
In Chapter 10 where the author discusses Ethernet shields he mentions that you need the "official" shield based on the Wiznet chipset rather than the cheaper ones based on the Microchip ENC28F60 chip. If you are new to Arduino I would recommend buying an extra board or chip in case you accidentally damage it.
It can be helpful for troubleshooting to try the same code on a different board to see if the problem might be with the board. Also, search the internet for "10 Ways to Destroy an Arduino" to avoid expensive mistakes. Simon Monk rules! By Juan I normally do not write reviews but I love reading them and deciding whether to or not to purchase the item of interest based on the satisfactory level of others.
So I now feel obligated to write a review. Monk the author of the book on page I will be honest I have not read all the book but from what I have read so far I can say it has not been much hands on which is not a bad thing; Monk sticks to his word and teaches you many concepts in a friendly manner. All his sketches are downloadable from his personal website and everything is wonderfully documented. I purchased another book since I am very novice when it comes to Arduino; "Arduino Workshop", a hands on Introduction with 65 projects by John Boxall.
I am reading both at the same time and OMG is life sweet to me right now. If you want hands on consider Arduino Workshop, but if all you want is to become familiar with the Arduino theory this is your book.
