Jumbo 20 Segment SPI (Serial) bar graph driver using 74HC595 serial to parallel converter IC and BC635 display driver transistor. This project is useful for application like Amusement machines, arcade gaming, voltage display, current display, pressure sensor display, temperature sensor...

IoT Fidget Spinner with Bluetooth Low Energy and POV LED Display by Uri Shaked. A smart, programable Fidget Spinner with the following features: JavaScript programmable 10-Pixel RGB PoV display (using APA102 LEDs) Spin count / speed detection using a magnetic latch Using Nordic...

Arduino Nano Bar-Graph display with universal op-amp shield consists of 10 LEDs and single low voltage general purpose LMV321 op amp including few capacitors and resistors connected to op-amp pins. The op-amp proto area can be configured without any modifications to the board and all...

4 Digit Multiplexed display shield for Arduino Nano with on board 2 tactile switches and LM35 temperature sensor. This shield helps you to develop many projects that require 4 digit display. For example a thermometer can be made using on board LM35 sensor.  7 Seven segment multiplexed...

1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET...

Chromatron is an open source Wifi pixel controller designed to make LED pixel projects easy and fun. Hi, I'm Jeremy! I've designed a toolkit for making art with LED pixel strips, and I'd like to share it with you! Chromatron takes custom designed hardware and feature-packed firmware,...

Martina @ natural-nerd.com build a sound reacting LED light using Arduino: Hi! In this build we’ll make a good looking light that dances to all sounds and music, using simple components and some basic Arduino programming. It makes an awesome effect while standing on the desk when...

Besides looking damned good on an otherwise bland and ordinary desk, this project is about more than just being attention grabbing eye candy.  It’s about demonstrating a small portion of our single board computer capabilities by hooking up a color sensor, RGB light strip, and...
