Arduino Uno Dot Matrix Display Using MAX7219 (Scrolling Text)
In this project, we interface an 8×8 Dot Matrix Display (MAX7219) with Arduino Uno to display scrolling text using the MD_Parola library. This setup is ideal for learning: All components, wiring, code, and flashing are available on a single page for smooth lab execution. Circuit Diagram (Arduino Uno + MAX7219) The circuit below shows the…

How to make a SONAR based on an ultrasonic sensor
SONAR stands for Sound Navigation and Ranging. SONAR uses the concept of ultrasonic waves that get reflected from the object in front of it. And the time it takes between the transmission and reception tells us about the distance it has traveled. Components Required After making the connection you have to make a sketch and…

How to make a simple Traffic Light using Arduino UNO
Everyone must have seen those big lights in red, yellow, and green color at the corner of every road. Some even flash. Some stay lit all day long. Big junctions have a separate controller which synchronizes these lights. So that the traffic flows smoothly. And the possibility of having a deadlock is minimized. That is…
