Learn about Arduino and the Arduino UNO and how you can integrate this make sure this tutorial was written for the absolute beginner with no experience. Libraries are a collection of code that makes it easy for you to connect to a sensor , display, module, etc. For example, the built-in LiquidCrystal library makes it.

Furthermore, make sure to get plenty of sleepmany a maker have gotten hurt while pulling all-nighters. Cleanliness is importantIf youre working by yourself, the temptation might be to let your workshop get messy. Dont do it! Youre more likely to have an accident in a messy shop than in a clean one. Be aware of your surroundingsKnow who is in the workshop with you and where they are in proximity to you and the tool youre using.
For instance, if youre using a power saw and a friend drops a wrench with a loud clang, an injury could result.
Know your toolYou should be respectful of your tools but not scared of them. If youre using a new tool, learn about it first. Either ask an experienced maker to check you out or, if you dont know someone like that, you can often find YouTube videos demonstrating how the tool is used. Similarly, use the tool for its intended purpose. Many people have been injured using a screwdriver as a pry-bar, for instance.
Know where your fingers areYou have ten of emideallyand you need all of them. When using power saws, welders, or even regular hammers, make sure youre aware of the danger and keep your digits safe. Keep a first aid kitIn addition to the usual stuff like alcohol swabs, adhesive bandages, and tweezers, be sure to stock gauze pads and tape in your kit because maker injuries can sometimes be serious.
Also, saline eyewash squeeze bottles are great for getting irritants or even sawdust out of your eyes. Chapter 8 provides complete descriptions of the ultimate makers first aid kit.
Dont forget basic safety equipment such as fire extinguishers and smoke detectors A sink is great, too. Every workshop needs ready access to a sink to wash off irritants or to rinse a wound.
In Chapter 2, Breadboarding, you learn how to create electronic circuits without soldering, using a prototyping board called a breadboard.
You also learn how to create a laser trip beam to protect your home from intruders! After youre up to speed on that, youll tackle your first project: a laser trip beam for your house! Youll also learn how to use a passive infrared sensor in place of the laser, as well as how to design and cut a plywood enclosure for your trip beam.
Assembling Circuits Using Solderless Breadboards Sure, you could make your project a tangle of wires, but sometimes a little organization can make a project easier to understand.
Often, for everyone from newbies to experts, the first step toward building a project is to breadboard it. Look at the project in Figure 2. If the creator wants to make a change, its incredibly easythe work of seconds. Its perfect for prototyping. Credit: Chris Connors A solderless breadboard is a plastic board covered in wire holes and featuring concealed conductors. These conductors in essence serve as additional wires for your project.
You simply plug in your Arduino, motors, sensors, and so on to the board and use it to manage the connections. Figure 2.
This photo shows the operation of a typical breadboard. The following list describes how each of the connections functions: A. Ground strips are usually marked in blue or black. Power bus stripConnect a power supply to power the strip. Note, however, that the two strips arent connected. Power strips are usually marked in red. Terminal stripsThe terminal strips are perpendicular to the bus strips.
Note that I have marked the terminal strips with light blue shading so that they stand out in Figure 2. Your breadboard will not be shaded in this way.
ConductorsThe blue strips indicate where the concealed connectors are positioned. Hole letters and numbersThese help you describe your project. For example, Plug the wire into H4 means you would find Row H and then count down to the fourth plug.
CHAPTER 2: Breadboarding Typical breadboards consist of two bus strips on each side, with a power strip, usually marked in red, as well as a ground strip marked in blue or black. Perpendicular to the bus strip are the terminal strips. These are the ones in the middle, and consist of short rows of wire holes linked together by hidden conductors as marked in blue in Figure 2.
Conductors are essentially wires, kept hidden so that your project is easier to wire up. Trying to decipher a huge tangle of wire is a lot to ask of a beginner. This allows you to write and compile code for the Arduino to execute, as well as providing a way for your Arduino to work alongside your computer. Installing the Arduino Software Package on Windows Head over to the Arduino website and download a version of the Arduino software suitable for your version of Windows.
The install includes drivers, so in theory, you should be good to go straight away. If that fails for some reason, try these steps to install the drivers manually: Plug in your board and wait for Windows to begin its driver installation process. After a few moments, the process will fail, despite its best efforts. Once the System window is up, open the Device Manager. Choose Browse my computer for Driver software. Windows will finish up the driver installation from there.
Extract the contents of the. You can copy it into your applications folder, but it will run just fine from your desktop or downloads folders.
Go to the Arduino website and download the Arduino Software for Linux. You can untar and run it with the following command: tar xzvf arduino-x.
If you downloadd a clone, you will almost certainly need third party drivers before the board is recognized over USB. Finally, click the Upload button on the top left of your environment. A few seconds after the upload finishes, you should see the pin 13 LED on the board start to blink.
This project will flash an external LED using a breadboard. Connect the short leg negative leg, called the cathode directly to ground any of the Arduino ports with GND on it, your choice.
This is a simple circuit. The Arduino can digitally control this pin. The resistor is necessary to protect the LED from too much current — it will burn out without one. This is where you can configure variables and anything your Arduino needs to run.
This can make larger projects more complex, but it works amazingly well for simple projects. Inside the brackets, you need to specify some additional information for this to work correctly. Additional information is known as parameters or arguments.
The first 7 is the pin number. If you have connected your LED to a different pin, for example, you would change this from seven to another number.
Once the LED has been turned on for one second, the Arduino then runs the same code, only it proceeds to turn the LED off and wait another second. Once this process has finished, the loop starts again, and the LED is once again turned on.
Challenge: Try adjusting the time delay between turning the LED on and off.
What do you observe? What happens if you set the delay to a very small number such as one or two? Can you modify the code and circuit to blink two LEDs? Connect the top right leg to Pin 4. Connect the bottom right leg to a 10k Ohm resistor and then to ground.
Connect the bottom left leg to 5V. You may be wondering why a simple button needs a resistor. This serves two purposes. It is a pull down resistor — it ties the pin to ground. This ensures that no spurious values are detected, and prevents the Arduino thinking you pressed the button when you did not.
The second purpose of this resistor is as a current limiter. Without it, 5V would go directly into ground, the magic smoke would be released, and your Arduino would die. This is known as a short circuit, so the use of a resistor prevents this from happening.
When you press the button, 5V is connected to ground. The hardware button you have used is a momentary action. This means it will only work while you are holding it down. The alternative is a latching action. This is just like your light or socket switches, press once to turn on, press again to turn off. Fortunately, a latching behaviour can be implemented in code. You need to provide it with a pin number 4, for your button.
