Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, ...

Some LED strips come with 2 extra wires for an external power supply, which are not required. There is sufficient power from the Arduino to light up a strip of 60 LEDs, however if you get a longer ...

which measures the intensity of light bouncing back from an object as an Arduino drives the LED through all possible colors with PWM signals. The sensor needs to be white balanced before use but ...

The LED comes into play by shining known wavelengths of light on the surface ... This time around it’s an Arduino doing the measuring instead of a PIC. So why isn’t that sensor shown in ...

YOu must have installed Adafruit_NeoPixel library. for installed this library press ctrl+shif+i or go to tool then manage libraries then search Adafruit_NeoPixel and install it.

We can get a very high torque servo motor in a small and light weight packages. The working of this Arduino smart dustbin is very simple. The ultrasonic sensor acts as the input and the servo motor ...

Perfect for beginners, this all-in-one package includes essential components like sensors, relays, LEDs, and more, making it ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors ... will be activated. The LEDs connected to those motors will also light up to show which ...
