That’s all about Arduino code. Let's feed this compiled binary code to the Arduino UNO R3 for converting the ordinary Arduino to a moving object speed-measuring device. Car Speed Detector using ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...
