Nick Smith – Magical Music Box using arduino

This is my Magical Music Box which converts music into a light show. When i was daydreaming what to make for my final project, i wanted something that would make a light show for any song simply by hearing it. Materials used: 1x arduino 8x 1k ohm resistors 5x 10k ohm 7x 560 ohm 3x 150 ohm 1x really really really big potentionmeter. so big its basically an on/off switch…. 4x RGB LED’s 8x .1 uF capacitors 2x ...

Introducing ESPToy 1.2 (with Lua Firmware)

A little while back I released the very first version of ESPToy — a ESP8266 Development Board with a few useful on-board components like color LED, button, and temperature sensor. It has a built-in ATmega644 microcontroller, and pin headers for plugging in a ESP-01 through-hole WiFI module. Shortly after that, I discovered the Lua firmware (named nodemcu) for ESP8266. At first I didn’t pay much attention — ...

Sleep Tracking using an Arduino

Background and motivation This project was motivated by two things: my almost complete inability to get out of bed in the morning, and my fondness for recording data from routine activities and making graphs with that data. My main problem with waking up in the morning is that feeling of grogginess along with an intense desire to sleep more. However, I've noticed that sleeping without an alarm clock, and ju ...

ESP8266: Arduino compatible $5 MCU with WiFi

This is the 1st part of a series of 3 posts on the new ESP8266 microcontroller I only talk about a bare handful of new boards because most of them don’t pass my test: whether they’ll let me do something today that I couldn’t do yesterday. But every once in a while a new board, or a chip, comes along that makes me sit up in my chair. The ESP8266 is one of those, and the things that make it interesting is tha ...

One wire brings power & data to LCD module

Embedded systems frequently use HD44780-type LCD displays as it is considered the most popular alphanumeric display controller. The interface comprises at least 14 pins: eight for data, three for control (EN, WR, RS), two for power supply (Vdd, Vss), and one for contrast (Vre). Configured in 8-bit mode, it requires at least 10 I/O lines (D0..D7, EN, RS). Configured in 4-bit mode, it requires at least six I/ ...

How to convert (almost) any 27 or 49 MHz RC Car into a Robotic car using arduino controller

I am teaching a robotics course in my kids high school (Rambam Mesivta in Lawrence, NY). I was looking for a cost effective way to teach them about the priciples of robotics without spending an arm and a leg, and getting them excited about the prospects of hacking hardware and teach them how to interface to the arduino platform. We studied H-Bridges made using  trasistors and switches, but there was somethi ...

[OoB] Shooting paintball maker with relay, Arduino and .NET WinForms

[OoB] Shooting paintball maker with relay, Arduino and .NET WinForms My first Arduino based project was Sonar with C#, JS and HTML5. Now I continue the "Out of Boredom" series with a setup that allows firing a paintball marker (gun) with a command sent from a computer :) This time software stack is simpler - just a small Arduino sketch and uncomplicated WinForms (.NE My first Arduino based project was Sonar ...

Arduino based high-altitude balloon tracker

One of the coolest projects I have done so-far with my kids is a "near-space" balloon. That's not quite into space itself (100Km+) but so high that the sky looks black and you can start to see the curvature of the earth below you. In order to take this kind of photo you need to send a camera up to the stratosphere. Ours went 38Km (124,000 feet) straight up. This is easy enough: you attach it to a massive ba ...
