Continuing with ATtiny85, today I’d like to share how to build a music spectrum analyzer on 16×20 RGB led matrix. The music signal FFT transformation and LED Bit Angle Modulation are all carried out by one DigiSpark ATtiny85. Please watch my video below: Step 1: Things We Need Main components are as follows: 1 x DigiSpark ATtiny85.

If you are like me, there are many nostalgic things that bring me back to my youth. Tom Sutton, username yakis on thingiverse, created this 3d model of Metroid’s Samus in morph ball form. It has room inside for LEDs to light it up. I have enhanced mine with a vibration sensor, neo pixel lights

Several months ago I got a really good deal on a large 32×32 RGB LED matrix display. It matches up with the wiring interface shown on the Adafruit website for their 32×32 display so I did the usual testing with their libraries. Recently I was looking for some ideas for projects for this display. One

In this article I describe how we made an hour glass with leds as the sand. We were always interested in making something that visually flows like sand and decided to use an hour glass to start. The movement is not completely fluid given the resolution of the amount of pixels, but it does resemble

This mini project is involved to use Arduino to control submersible watre pump when soil reach below or above predefined moisture level. How it works ❓ 1. Soil moisture sensor is reading analog signal which transmit to Arduino. 2. Arduino control submersible water pump ON or OFF. Water pump operates when moisture level reach predefined

Hello everyone, today I’m going to show you how I built a Mini-TV weather station with Open Weather Map and the ESP32! Background and Troubleshooting I’m not kidding when I say the inspiration for this project came from boredom! I had been working on the same project for a long time, but enough was enough and I

Welcome to this instructable, this time I will be showing you how to make the newest version of my ARC Reactor Mood lamp I did a couple of months ago. This time it won’t be a mood lamp, but a lamp that changes depending on the different colors used by Iron Man Suits in the

I do project related works. After the structure contractors finished their building works, they threw away a lot of washers and nuts M10. During I did cleaning, I picked them up to make this decorative see-through led project. It can be viewed from frontside or backside by a push button. Let’s watch videos bellow before

Hey everyone what’s up! so you got yourself an esp12f module and now you want to program it? here’s how you can do that in an easy way that doesn’t involve that complex FTDI module with the button’s method. so the easy way is to use a Nodemcu here. actually, the trick is to use

This command-line Python script is a utility to help calculate parameters for timing belt drive systems. A more general discussion of designing with timing belts can be found on the Timing Belt Guide pages. Installation Requirements The code requires a working installation of Python 3 with scipy. For suggestions on setting up your system please see Python 3 Installation.
