I`m going to show you how to use your Arduino to control up to 12 servos at once with minimal jitter. Using a simple serial interface you can control the position of up to 12 servo channels. Up to 10 snapshot positions can be saved and played back at any.... -
But the idea is to apply this code to other projects with 7 segment displays that I might do later. if you want to learn a bit more of 7 segment displays you can read more at this post I`ve made. .. -
The Arduino Internet Gizmo is a USB, Arduino, and RFID device for web surfing. The gizmo works by placing an RFID tag on the top of the gizmo. The gizmo reads the RFID tag and sends the tag number via USB to a program running on a PC. The program looks up.... -
Basically I used the parts list that is on the first page of the Make Magazine article. But that list is for the harp which has 6 lasers so most quantites can be just 1. .. -
Setup the lights on the breadboard like a traffic light. Red on top, then yellow, and then green. The small red and green are the pedestrian crossing signals. Again red on top and green just below. Put the buttons in so you have at least 2 pin holes space to.... -
I already have one project where arduino outputs audio signal to USB speakers via software 10-bits PWM. In first, I was not satisfied with quality of sound generated via PWM. There are just not enough speed in arduino engine to run PWM well. For example for.... -
Often government data sets available to us online are taken from major nearby metropolitan areas or infrastructural centers. With an easy to follow introduction to new softwares and technologies the urban sensor kit allows anyone to obtain location.... -
Measuring the consumption of a resource that has units by volume can be more tricky than it sounds. Use of resources such as water, gas, and even electricity is typically measured by gauges that determine either instantaneous flow rate or cumulative volume.... -
Water is a precious resource in many parts of the world, and many people rely on water tanks to supplement their water supply by storing collected rainwater or water pumped from a well or bore. But how do you measure how full a tank is Tanks are constructed.... -
I`ve been working on a project that will allow me to determine the number of sun hours available in a given spot, and track that over time, as a component of solar power installation design. The idea is to get a light detector in the sun, record the number.... -
I wanted to teach my Arduino to talk telephone, so I added a HT9000A DTMF chip to produce the familiar "touch tones" (upcoming projects will act upon "heard" DTMF tones, but with a different chip). The output is really low volume, so you may want to plug in.... -
To power it up you need a clean stable source of 5 volts DC. This means that you either pick up a switching 5v DC power supply from our favorite JK Electronics, mail order one from Jameco or you will have to wire up a voltage regulator. Page 254 of Phys Comp.... -
I love the Arduino as a simple and accessible controller platform for many varied projects. A few months ago, a purchased an Ethernet shield for my Arduino controller to work on some projects with a mate of mine it was a massive hit for the first time, I.... -

DESCRIPTION This project is to make a clone of Arduino Leonardo in a simple way.That is why the distribution of the pin does not match the standard Arduino... -
software on my MacBook Pro - such as the aforementioned Laidman & Katsura `s WaveWindow - WaveWindow is a software oscilloscope. It`s useful for anyone who works with sound on the Mac; it`s educational and fun to play with. and Faberacoustical `s Signal.... -
Nothing really new: a JFET is used to sense the electric field generated by high voltage electric line; the JFET amplifies the signal very little, but it lowers the impedence and provide current to a level suitable for transistor amplification. The two.... -
Agy used for the first time Lilypad Arduino and LED s on a textile project called Blinky Bike Bag, combining her expertise in fabric hacking with electronics: The bike bag is made from umbrella material to make it waterproof, and I made it with safety.... -
This evening as I came home from a paragliding appointment, I had a feeling that I must improve my yesterday-written RGB LED driver code. So I cleaned it up a bit, and wrote a lot of comments to make it more useful for educational purposes. I`m alredy over.... -
The power controller module used in the system takes input directly from a momentary switch and uses that to toggle a relay that passes mains power to the system’s transformers. The controller circuit operates at 12V and as I understand was chosen to allow a.... -
Well I finally got round to purchasing an Arduino Uno Open Source Prototyping Platform and first impressions are... -
First thing`s first, what software to use I went with CadSoft Eagle primarily because there are lots of tutorials out there covering it, and that seemed like a good place to start. Once I understand the process I can worry about what software I use, but for.... -
Before I emailed Pablo Gian Villamil and he sent me on a link to his class notes (yay!) for Generating polyphonic sound with Arduino I tried to work out his circuitry from his various blog posts and component listings CMOS Hex Schmitt Trigger Inverter.... -
Arduino Uno a simple hack that bypasses the USB circuitry to program the device with a serial port... -
As a fully-featured Linux computer there are many external programmers that can be used with your Raspberry Pi to program the Atmel AVR range of microprocessors. It`s also possible to use the general purpose input/output lines (GPIOs) found on the Raspberry.... -
Working on the brightness problem, I know that the 4017 design did not work well because there was no way to turn off the sign while updating the shift registers. As a result I went back to having the Arduino directly drive the TIP120 drivers. Another.... -
I havebeen researching a project which will help me with my understanding of electronics, networking, and programming. I decided to build an online thermometer which could be used in applications that need temperature monitoring. I currently work in a lab.... -
This project implements a network connected water level sensor, measuring the level in the sump pit of my house. It`s connected to the home network and reports the water level by broadcasting UDP packets so that any computer can receive it and take action,....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
