How does an Arduino control the brightness of LED using a potentiometer? Take a sample of the potentiometer with an A0 pin of the Arduino, which has a resolution of 1024 values (10 bits), and convert the potentiometer output voltage into an integer value between the range of 0 to 1023 vo...
In addition to that, using the right potentiometer we can adjust the controls responsiveness, or reduce the amount of servo travel, and using the left joystick we can sub-trim the rudder or adjust the neutral position of the servo arm. Oh, and I almost forgot the mention, the main feature...
In this tutorial I will show you how I built an Arduino hexapod. As the name suggests, the hexapod has 6 legs but in addition to that, it also has a tail or abdomen, a head, antennas, mandibles and even functional eyes. All of this, makes the hexapod look like an ant, so therefo...
Many advanced options require hardware support to work. So, by default, they are set to -1, which means ignore.Specify Servo ResolutionBy default, the software will have a servo resolution of 180 positions. While most hobby servo controllers (i.e., Arduino, EZ-Robot EZB) are limited to ...
A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a professional-grade line follower robot using Arduino UNO, with complete code explanations and tr...
Arduino IDE Betaflight Configurator A phone that supports bluetooth. A Micro-USB for data transfer 10k Potentiometer(Optional but recommended) This is a list of all of the tools needed for the project: A soldering iron Soldering wire Wire strippers ...
a digital signal. Aside from that, we have an integrated 10K potentiometer for adjusting the sensitivity of the MQ-3 Alcohol Sensor module triggering voltage. Aside from that, there are two LEDs. The power LED is the first, while the trigger LED is the second. When power is provided to ...
R2 is a potentiometer that is used to control the sound volume. C2 is a capacitor that sets the voltage gain of the LM386 amplifier. Therefore, the voltage out is 200 times the voltage in. This provides us with the maximum gain that the LM386 can provide. ...
How to Make a Line Follower Using Arduino: If you are getting started with robotics, one of the first project that beginner make includes a line follower. It is a special toy car with property to run along a line which normally is black in color and in c
The Arduino has always been used to control motors. A few examples would be the DC motor, servo motor, and stepper motor. Today, we are going to cover 2 motors, DC and Servo Motor, which are widely being used by many electronic hobbyists and makers due to their simplicity and functions...
