We need the ability to control voltage in a circuit. That's the purpose of the potentiometer.
In order for computers to function, there has to be a method of communication between the user and the machine. The commands of analogRead and Serial.begin opens that line of communication.
Adjusting the voltage output between 0 and 5 volts using an Arduino
Congratulations! You have mastered the basic skills of electronic design and Arduino coding. Now its time to move to the advanced stages of implementing Arduino into more complex projects. We'll start with "strings" and inviting a third party to use the Arduino. The third-party may not understand coding or Arduinos therefore, it's our responsibility to create a user-friendly environment.
Designing and coding a Binary Counter with an Arduino
How to build a dimmable LED. You will read values from a potentiometer, and then based on what values you read, you will set the brightness of the LED.
For Loops, which will allow you to control the conditions of the Loop. This is a very powerful programming technique, and it will allow you to take your projects to more advanced levels.
Allow you the opportunity to code your programs to branch into different directions depending on values that you are reading from sensors.
Arduino is an open-source electronics platform or board and software used to program that is designed to make electronics more accessible to everyone
In order to design and analyze a circuit, we need a working understanding of Ohm’s Law.
The analogWrite command only approximates analog voltages and does not produce an actual analog signal. It works by quickly turning the voltage to the pin on and off or pulse width modulation.
While loops give us increased flexibility in our coding. For loops are based on counters, while loops are set on parameters.
Drafting is a highly refined form of drawing used to communicate ideas to engineers, architects, and craftspeople. In earning this badge, Scouts learn the importance of accuracy and simplicity in developing a drawing that shows precise details in a simple format.
Learning how to solder with proper soldering techniques is a fundamental skill every maker will need to master.
Scouts will begin their work on this merit badge by learning about the properties of metal, how to use simple metalworking tools, and the basic metalworking techniques. Then they will practice using these tools and techniques before concentrating on the more intricate skills of one of four metalworking options.
With the fun of operating a motorboat comes the responsibility for keeping that boat in first-class condition, knowing and obeying the nautical "rules of the road," and gaining the general knowledge and skills to operate a boat safely.
Earning the Robotics merit badge requires a Scout to understand how robots move (actuators), sense the environment (sensors), and understand what to do (programming); he should demonstrate robot design in building a robot. You should help ensure that the Scout has sufficiently explored the field of robotics to understand what it is about, and to discover whether this may be a field of interest for him as a career.
The future will depend on alternate energy resources. Solar generated power is becoming reliable, sustainable energy for the future
People use countless fibers and fabrics in their everyday lives: clothes, carpets, curtains, towels, sheets, upholstered furniture. Add to that list boat sails, book bindings, bandages, flags, sleeping bags, mailbags, airbags, seat belts, backpacks, parachutes, umbrellas, basketball nets, and more.
Opportunities in the welding field are endless, and Scouts earning their welding merit badge can not only explore the fundamentals of welding but also learn about the different career paths within the industry.
