The schematic for this project really only consists of adding a single 5mm LED to one digital output port on the Arduino. The picture below should be fairly self explanatory for how to do it. The main parts in the schematic are the Arduino Uno, 5mm LED and USB Cable. The far left side of the Arduino board (as seen above) has both the DC power j

ack to supply power for mobile operation and the USB connector for supply power + programming. This USB connector actually connects to a seperate Atmel microcontroller which acts like a translator to convert USB to serial information passed on to our ATMega328 that the Arduino bootloader understands. The 5mm LED that we will add to the digital output 12 will be used to help prove that we can run both a standard example program and a modified Arduino program. Normally a current limiting resistor should be placed before LEDs, in this case since we won`t be using the LED or Arduino in this configuration for months on end, the LED will not be damaged by connecting straight to a digital output. This is the platform that I am using, however you are free to use any of the standard Arduino platforms as they all have similar features and you can follow along with this article no matter which one you have.
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.....
