Although the best choice is A0 and A1 pins for input and 1 and 9 pins for after.
The Photon Factory made at the University of Auckland which is a laser lab, have been working on the electronic building of a nanosecond transient absorption spectrometer, which will be responsible for exciting molecules initially and then detecting the excited state. Further, another laser will look out for the length of the stability of the excited states, which will be used to do research on photoactive molecules. The molecules are made up of nanoparticles that can convert sunlight into energy. Fullerene triad molecule is the type of molecule where light excites an electron in the porphyrin and then fullerene takes up the electron.
A simplest electric motor contains a drywall screw, one 1.5 V alkaline cell, six inches of plain copper wire and one small neodymium disk magnet. That’s it, you don’t need any other tools or supplies and in 30 seconds, an electric motor can be made that can run in excess of ten thousand RPM. Windell Oskay confirms this idea.Brushed DC electric motor is the most common type of electric motor and they are found essentially in every object that moves or run on batteries. The specialty of the motor is that it attracts an electromagnet towards a permanent magnet and when the two are close enough, the polarity of the current is reversed, which now repels the permanent magnet.

Almost everyone with a laptop has experienced that how easily the power adaptor of the laptop breaks down. The most vulnerable and common part, the adaptors are directly attached to the motherboard as well as heat. Moreover, it is constantly moved and shifted that causes the connector to become loose and sloppy. This combination, in due course, causes the connection to stop working altogether.To solve this problem, Apple, in their laptops is using a magnetic power adaptor but they have patented this idea. Diyourself has come out with their own version of a magnetic power adaptor for an Acer 1410 laptop. One can easily amend the steps provided for Acer to any laptop. They are not only effective but comparatively easy to build with some common materials.
If you want to check the level of charging of a battery, then one can use an Arduino battery tester. It can be an attractive tool to detect the leftover battery and then how to use them judiciously. This project is categorized as a basic Arduino project for beginners and hence can be extended to a proper setup.The project includes equipment like Arduino Uno, Green, red and yellow LED, Zener diode, resistors, and breadboard. The Arduino Battery Tester Circuit is easy to assemble, where the Zener diode is used to test batteries with a voltage greater than 8 volts. This diode allows current to flow in one direction and it reaches the breakdown voltage, from where voltage goes in the reverse direction.
Daniel Andrade, on his website, has discussed how to program a binary clock with limited equipment in the easiest manner. To make this device, he has only used Arduino, LEDs, resistors, breadboard and buttons. The circuit is also quite simple and he has explained its working and the process of assembling them through videos and diagrams.The LEDs placed on the breadboard, which is on, are needed to sum together and then it will give the current time. In order to assemble the circuit, firstly the resistors and LEDs are connected together, and then both of them are hooked together from the pin 1 to 13. As the bigger leg of the LED is positive, it is connected to Arduino output pin while the other leg remains on the ground.
With a goal to develop an inexpensive spectrometer, bhickman on his website has designed and explained the process of making an affordable spectrometer. The resolution of the same is comparable to lower end commercially available spectrometers. Further, approximately 0.6 nm wavelength resolution is being provided by the current design and around 12-bit intensity resolution.Generally, spectrometer should operate in the 400-900 nm wavelength range but to get the exact wavelengths, some changes are needed because of the discrepancies between the theoretical and actual design. Hence, a halogen bulb has been used as the light source and the design is accordingly modified to handle the heat generated. Further, some thoughts are required to find the way to eliminate higher order light interference.

They designed a rough sketch accordingly and gained some information about designing plastic parts from tutorials on YouTube.
ADM3A is a dumb terminal with discreet logic chips and no major integrated circuits. In this post, an anonymous blogger has made an attempt to put this terminal online to snag a picture of it on retro.hackaday.com but unfortunately, it didn’t work out. After sneaking parsley to the parts of this device, he discovered that a big clunking mechanical power switch has failed to work. The 37-year-old electronics switch had gotten dirty and corroded, therefore, he cleaned it out and luckily, now it is working again.He made MAX232 serial adapter for a raspberry pi and then hooked the Pi up to the terminal. The adopted serial adapter here is just a typical MAX232 circuit and one can purchase them online. After figuring out that the header for the Pi can be put right on the board to replace the headache of making an adapter cable, he concentrated to hook up the tx and rx lines.

The advantage of having a techie at home is a blessing in disguise, especially when we get stuck with electric mishaps. Whether it’s a special occasion or an effort to introduce something innovative in the house, they are always at the rescue. This article by Brandon Cannaday, has aimed to make an LED dice roller using an Arduino. Inspired from the game of monopoly, where dice rolling is a pretty integral part of the game, has made the game more interesting and also provided an opportunity to bring together your friends and family to play a game. The amended dice is made up of seven LEDs, a button, and an Arduino Uno and when a button is pushed, the dice automatically “rolls” for a while and then lands on a random number.
One of the Henry’s Bench tutorial has tried to explain the characteristics of the Logo Version 1.3 Flame Detector module. It represents all those similar devices which are specially designed to interface with microcontrollers. The device also consists of op-amp circuitry, an IR detector, an LED indicator, and sensitivity adjustment.The most important portion is the IR detector, which is sensitive to light wavelengths and hence typical of flames. It means that when a flame is presented, the red LED of the module is turned on and its output low is accordingly set.
