Today I will share following topics base on a bicolor matrix led 32×32: D.I.Y a bicolor led matrix 32×32. How to control led board above with NodeMCU ESP8266 via B.A.M method. Introduce and share my code for some cool real time clock projects with this bicolor led board. Let’s start with some videos: Rainbow letters […]

I recently finished the installation Equally diverse, which is made of a series of lamps that react to the sensors placed in a rug underneath the lamps.Here is how I made the rug with pressure sensors.I hope you will find it useful. 🙂 Step 1: How to Make the Sensors For the pressure sensors, I

For many kids, the tin-can telephone is a fun science experiment that doesn’t last much longer than it takes to tangle the string around a nearby tree. [Geoff] decided to go a different however, building a tin-can telephone that’s completely wireless. The build starts with a hacker favorite, the Arduino Uno. It’s hooked up to an

Where won’t they put a TV these days? We’ve even seen one creeping behind semi-transparent mirror film in the ladies’ room of a sports bar, though that one didn’t last long. Up until that moment, we had never wished so hard for a TV-B-Gone, especially one as small and powerful as this DIY version by [Shane].

This is my first instructable, I hope you will Like It!! Basically, In this Project I have used the Serial Communication between my Arduino and my Laptop, to transmit music data from my laptop to the Arduino. And using the Arduino TIMERS to play the data as a PWM signal. I wanted to mention that,

This seven segment art display makes use of a 81 seven segment red common cathode LED displays. The LEDs are arranged onto 100x100mm boards that each contain an Arduino Nano and 9 seven segment displays, daisy chained through three-pin headers located on the sides of the boards. The pins (power, ground, and serial) provide the signals necessary

There was a time when an intercom was simply a pair of boxes with speakers joined by a couple of wires, with an audio amplifier somewhere in the mix. But intercoms have like everything else joined the digital age, so those two wires now carry a load of other functionality as digital signalling. [Aaron Christophel]

This interactive wall art piece is approximately 39″ tall and 24″ wide. I laser cut the wood at Clemson University’s Student Makerspace, then I hand-painted all the triangles and installed the lights on the back of it. This instructable will walk through how I made this exact piece, hopefully the concept of it will inspire

If you are looking for a tiny three-color E Ink display, the Wemos D1 Mini board can fit the bill perfectly, more so given that it comes for just $10 a pop. Developed by Lolin, the display is all of 2.13-inch having support for red, black, and white colors. Further, the display has a resolution of 214
2.13 inch tri-color E-Ink display for Wemos D1 Mini board is only $10 Continue Reading
We’ve seen a number of heart rate monitoring projects on Hackaday, but [Peter’s] electrocardiography (ECG) Instructable really caught out attention. If you’ve followed Hackaday for any period of time, you’re probably already somewhat familiar with the hardware needed to record the ECG. First, you need a high input impedance instrumentation amplifier to pick up the millivolt
