How to Use a Magnetic Door Switch / Sensor With Arduino: In this tutorial we will use one magnetic - contact door sw / sensor and a buzzer for making a "noise" when a door is opened. Normally the reed is 'open' (no connection between the two wires). The
Pin Plugs: A pin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which ...
In this tutorial, we will be building a simplearduino maze solving robot. The robot uses IR sensor to detect the maze and employs an algorithm called hand on wall rule to navigate through the maze and find the exit. Please note we have used lines to create the maze instead of building w...
How to Use switch in React (JSX) JSX is a React syntax that allows us to create components and UI elements without using the .createElement() function. It also has many additional features that HTML doesn’t have. For instance, you can write regular JavaScript code within JSX. All you mu...
The ‘does not name a type’ error is an indication from the Arduino IDE that it was unable to find a definition for something that you’re trying to use. The most common cause of this error is when you are trying to declare or use a variable or function that doesn’t exist. ...
So, if you applied all the steps presented, you were able to learn: Basic operating circuit of the DFMini Player MP3; Organization and configuration of sound files on the memory card; Musical control with Arduino. From this code, you are able to develop other projects that need to use sou...
Arduino EEPROM functions EEPROM Read and Write Bytes The basic unit of an EEPROM transaction is a byte. To read and write these bytes you can use the following functions: EEPROM.write(address,byteValue);EEPROM.read(address);// returns a byte. ...
ok so i am new to arduino. i am trying to have one button turn on the led witch is in pin 13 and another button to turn it off but im having problems. when i press the button it turns on when i let off the button it goes off. here is my code so far.c
Pin connection of Arduino Uno with the Motor driver are as follows: Here, we are using a 7.4 li-ion battery to power the whole circuit. You can use any battery type from 6-12 volt. To move the robot, we need to use motors with low RPM but torque high enough to carry the weight...
Use Two or More Values for Oneswitch-caseStatement The multiple case labels method provides an elegant solution to this challenge. This section will explore how this method enhances code clarity and efficiency by handling multiple values within aswitchstatement. ...
