Once you have your circuit diagram, move on to step 2. Make Your First Printed Circuit Board Download my guide with all the steps you need to design your first printed circuit board (PCB) from scratch. Download Guide Step 2: Draw Your Schematics First, you need to install aPCB design so...
In this post, I will show how to construct a calculator using Arduino, which can perform far complex arithmetical calculation than an ordinary calculator. The motto of this post is not to make a calculator using Arduino, but to showcase the arithmetical capability of Arduino, which performs var...
Pins 7, 6, 5, 4 and 3 are connected to the digital pins of the display. It is not mandatory to know how the arduino communicates with display in order to use it; we will add appropriate library files to the arduino software which will take care of the communication between arduino and...
The most common type of LED matrix used with the Arduino is the 8×8 LED matrix. Individual 8×8 matrixes can be combined to make larger displays. In this article, we will see how to print text to both individual and combined LED matrix displays. As an example project, we will also s...
The control pins of the six servo motors are connected to six digital pins of the Arduino board. For powering the servos we need 5V, but this must come from an external power source because the Arduino is not able to handle the amount of current that all of them can draw. The power ...
Related Tutorial:How Servo Motors Work & How To Control Servos using Arduino For powering the robot I will use a 3S LiPo battery which has a voltage of around 12V. LiPo batteries can handle higher amount of current draw, so they are suitable for this project because if all servos are en...
Below is a relay wiring diagram that shows how to use a relay switch with an NPNtransistor. This is useful for when you want to control a relay from things that can’t drive relays, like an Arduino, or an integrated circuit from the4000 seriesor7400 series. ...
Most displays that exist for the Arduino UNO are expensive in large display sizes, processor intensive; requiring the Arduino to draw the display or pin hogs; using up most IO on the Arduino. The Nextion display is a “Smart” display; it contains its own processor, Inputs and Outputs, me...
The history of FPV drone flight controller can be traced back to 2009, when a maker used the Wii Motion Plus Accessory with an Arduino board to control a drone. This led to the development of theMultiwiiproject, which eventually created its own flight controller board that worked on an 8-...
The ESP32-CAM AI-Thinker development board can be programmed using Arduino IDE. Learn how to program and upload code to the ESP32-CAM AI-Thinker dev board.
