When we’re working with LEDs, we often like to control their state (on/off), brightness, and color. There are many, many different ways of going about this, but none are as compact a solution as the WS2812 RGB LED. In its tiny 5mm x 5mm package, the WS2812 includes 3 super bright LEDs (Red, Green, […]
Today I would like to share how to make a sculpture circuit that controls 16 RGB leds using ATTINY85. We can adjust their colors separately according to the colorwheel rule with a touch button. Step 1: Things We Need The main components are as follows: 1pcs x DigiSpark ATTiny85. 1pcs x Shift Register 74HC595N. 1pcs x Power Logic […]
Have a nice day, in this instructable I’ll explain how to make a little decorative display for your desktop. It connects to your PC via USB and you can upload any image you want (240*240 BMP) It uses an Arduino pro micro for the serial connection and a ST7789 LCD display, I decided to use […]
An 8x8x8 LED cube is a visual treat with 3D effects and patterns. It works on the concept of Persistence of Vision, a feature of the human eye which tricks our brain in to thinking that an object is present permanently at a place if it appear about 60 times in a second. Since an […]
The dryer in our house is in an out-of-the-way corner where it’s hard to hear the buzzer. When we miss it, the clothes sit in the dryer getting wrinkly, so we start the dryer again, don’t hear the buzzer again … it’s an endless cycle. After what seemed like the thousandth time, my wife quipped, […]
In Amateur radio, Morse code is used to send messages using a series of short or long pulses which are heard by the operator as audio beeps. The short beeps are known as dots or dits, and the longer beeps are known as dashes or dahs. To be understood, the duration of the dits and […]
This project will show you how to create a computationally enriched puppet that can detect magnetic fields. The puppet (who I call Compy) has two very sensitive GMR analog magnetic sensors that are located in her beak, these sensors are read by an Arduino Nano that actuates a 3×3 haptic display (Figure 3) based on […]
This Instructable is to build a very smart, talking campsite security system that is disguised in an owl decoy. Now, this isn’t your typical Arduino ultrasonic distance sensing project. Rather, you will learn how to reverse engineer the very inexpensive, but far superior automotive bumper backup sensors for very wide beams of detection. You’ll also learn how […]
In a couple of weeks, some students will visit my lab (Craft Tech Lab) to learn more about wearable technologies. I wanted to build a quick and simple application of a sensor and vibration motors for them to play around with and rough up. While this project could be made into a wearable mask, due […]
With this small, palm-sized device, it is possible to remote control your PC or your Smartphone. Or to control your PC and your Smartphone at the same time. And it is freely programmable. You can write programs like: Login to your PC, open and login to instructables.com, play/pause a movie or adjust the volume on […]
