I wanted to have an easily programmable RGB light to toss into a Jack ‘O Lantern for Halloween. Who really wants a dull pumpkin in these days of pumpkin pimping madness. So I set to work building a pocket tin sized RGB lamp that could be reused after Halloween for some other RGBing need. The […]
Overview The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support […]
This Lazy Old Geek is also an Arduino Geek. If you are an Arduino Geek, one of the common microcontrollers used by Arduinos is the Atmega328 chip. In order to use Arduino software, the Atmega must have bootloader software on it. Okay, so I bought some blank Atmega328-PU chips from Mouser.com. TIP: If you want […]
We have kids. I love them to bits but they keep hiding the remote control for the satellite and TV when they put the children’s channels on. After this happening on a daily basis for several years, and after my darling wife allowing me to have an Arduino for Christmas I decided that it was […]
We have all seen the sweet videos on the tube! You know the magical water fountains that seems to “freeze” the water droplets in mid air, or even make them go backwards! I’ve been fascinated by these “magical” thingamabobs for quite some while now, and a couple of days ago I decided to make my very […]
A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro-mechanical machine which is guided by computer or electronic programming, and is thus able to do tasks on its own (http://en.wikipedia.org/wiki/Robot). Well, today you will learn exactly how to build a Homemade Magic Lamp Card Box. Really, this is two instructables […]
Arduino Fart-O-Meter Project Innovation in electronics often emerges from playful experimentation, and this project—though humorous in concept—demonstrates practical use of wireless communication and sensor integration. The Arduino Fart-O-Meter is essentially a system designed to measure methane emissions (commonly associated with human flatulence) and transmit the data wirelessly to a receiver unit for visualization. Project Overview […]
I use Arduino Duemilanove With Motor Driver Shield Microcontroller ATmega168 Operating Voltage 5V Input Voltage (recommended) 7-12V Input Voltage (limits) 6-20V Digital I/O Pins 14 (of which 6 provide PWM output) Analog Input Pins 6 DC Current per I/O Pin 40 mA DC Current for 3.3V Pin 50 mA Flash Memory 16 KB (ATmega168) or […]
This is a follow up to an earlier Instructable for attaching the guts of a cheap clip MP3 player to an Arduino. http://www.instructables.com/id/MP3-Interface-for-Arduino-Cheap-and-Easy/ The previous Instuctable showed how to use the Arduino to control all of the functions of the MP3 player: volume increase and decrease, next and previous MP3 file, play or pause. The previous […]
In this, my first Instructable I’m going to show you how to make a stripped down Arduino for a fraction of the price, using Stripboard/Veroboard. Material List: 1x Atmel ATMega168 = �2.65 1x Stipboard = 72p 1x 7805 Voltage regulator = 26p 2x LEDs = 16p 2x 220 Ohm resistors = 8p 1x 10k Ohm […]
