Nixie tubes are really cool looking and are becoming quite popular for their ‘retro’ look. Although there are a number of tutorials out there on using nixie tubes and some nice pre-packaged units (see these nice ones from ogi lumenand ArduiNIX) I hadn’t seen a simple tutorial on running them using a shift register like the SN74HC595. […]

The Arduino Integrated Development Environment, or IDE for short, is constantly improved, updated, and features Update Arduino IDE with new features and bug fixes.  Keeping your IDE up to date ensures you have the latest capabilities and a stable development environment. This tutorial will guide you through the various procedures for updating the Arduino IDE […]

GoFly is a project based on PNA (car navigation devices with Windows CE), LK8000 tactical fligh computer software and variometer (altimeter) external input based on Arduino board and pressure sensor. Why? -You can build this for about 150$, -Your ordinary PNA (Personal Navigation Assistant) changes to really nice, high end flying computer, with lot of […]

Being able to control everything from your pocket has long been a dream shared by many. Previously we’ve had universal remotes that can both control our TVs and radios, then we had wireless wall sockets. Both great things, but how likely is it that you’re going to be carrying around those remotes with you everywhere […]

In this tutorial you’ll learn how to use a bluetooth module and MIT’s app inventor to create a wireless serial link between an android phone and an arduino board. Here is a short video showing an example app I created. I’ll describe how to do the wiring, write an arduino sketch that can accept basic […]

What are we messing with? IoT (Internet of things) set-up to operate/control 220-240 Volt AC Bulb/Device NodeMCU Amica + 5V Relay + MQTT + Arduino IDE + Web Browser (HTML + JavaScript/jQuery) WARNING!! – THIS PROJECT INVOLVES WORKING WITH HIGH VOLTAGES THAT CAN CAUSE SERIOUS INJURY, DEATH, AND/OR SET YOUR HOUSE ON FIRE. PLEASE PROCEED […]

Step 1: COMPONENTS REQUIRED Only 4 components required – 1. ESP8266 NODEMCU or WEMOS D1 mini or any esp8266 wifi development board2. RELAY (5V or 6V)3. ULN2003 or UNL2003A (Relay driver IC)4. Jumpers (obviously or else solder it!!) The main structure of the project is that ESP8266 module will receive the signal from the MQTT […]

Overview As enthusiasts of audio, we aimed to use our recent understanding of microcontrollers to create an exciting consumer gadget. Our project is a drum machine that functions as a step sequencer. The user can create a 16-step percussion sequence with various percussion instruments on six separate tracks. The user switches between various music tracks […]

LED displays are commonly packaged as arrays of LEDs organized in rows with shared positive terminals and columns with shared negative terminals, or vice versa. Here is a standard illustration, along with its diagram: These exhibits can be very useful. To control a matrix, you connect its rows and columns to your microcontroller. The columns […]
