and can do plenty of cool things with analyzing audio signals. In our case, it uses the fast fourier transform of the audio signal from the mp3 to analyze certain frequencies, and lights an LED if certain ranges of frequencies go above the allotted "sensitivity" value...
it is not guaranteed. The best way to know the connections is to obtain the datasheet for the LED display in use or to buzz it out by connecting power to each of the pins to see which lights up. If you don't get the connections right, the circuit will not produce the output...
Today I'll be showing you how to control your Hue lights from an Arduino - then adding a simple motion sensor.
For a more complicated lighting setup, four lights are used. All set to the fastest settings of 195 microseconds and triggered all together. The flash A does most of the work illuminating the water vapor cloud with a colored gel as the balloon pops. The light B gives a white light t...
Once registered on the site, go to device and press add device. In the menu that is shown to manage lights, choose the Actions "ON and OFF" and "Type Light" as Application; Fil the boxes with your username and the password you’ve chosen in step 2 into the settings of the Alexa Ho...

Screw these LED bulbs into your regular fixtures, install the app to your phone or tablet, and then you can turn the lights on or off, brighten or dim them, or perhaps best of all, change the color. Then you can even program the lights to perform just about any combination of color ...
You can use a microcontroller, such asArduino, to create the logic for when to turn your lamp on and off, then use an electrical relay to do the switching of the lamp. This makes it easy to make lights that activate only at night, control your garage door motor with a signal generated...
Orient the LED as in the figure below. With the longest lead, the anode (+), to the right, and the shortest lead, the cathode (-) to the left.Using a needle nose pliers, bend the longest lead backwards with a 90º angle. As shown in the figure below. You should do this to ...
This is the next part in our learning Arduino series, and this time we’ll be learning about and using Arrays to make a little Christmas tree ornament with various flashing sequences. This would be an ideal project to keep the kids occupied if you'd like
