The Fun of Developing Arduino-based Talking and Remote Thermometer

For the home hobbyists, life would be extremely boring without the existing of Arduino projects! If you’re looking for some interesting Arduino-based project, then you’ve came to the right place… Guys, today you’ll have the opportunity to build up a fantastic Arduino-based Talking and Remote Thermometer. This project isn’t a hard task, especially for the professional home hobbyists. By the way, you should prepare the following components: An Arduino (With one free analog input port); A Solderless Breadboard; A 10k resistor; A 10k NTC (Negative Temperature Coefficient) Thermistor. It’s time to kickstart the project! First of all, you’ll need to use the Power (+5v), Gnd (Ground) and one of the Analog-in connectrors (Pin 0) on the Arduino. For your information, the Analog-in connectors are normally located near bottom right-hand corner of the board. Furthermore, you’ll notice that the Power connectors are situated just to the left of analog-in connectors! After that, you’re going to set up the 10k NTC thermistor and 10k resistor on the breadboard. Before you ended up the project, please make sure that all connections between the… Continue reading

The Simplest Arduino Realtime Audio Processing

Do you believe that with some little modification, some of the realtime audio processing can be done with using only Arduino? You still can’t believe it, then please stick with us and read on the article… For this project, the audio input signal is connected via a 10uF capacitor (Remember that you have to use 10uF capacitor, or else it won’t be success!) to the analog input 1 of the Arduino board. Then, you need to add two resistors and a trimpot to the audio signal. After it, a potentiometer is connecting to analog input 0 (This is used to control the audio effects). The pin 11 will be used as PWM audio output connected via RLC filter to the audio output jack (You can choose to connect the output to an active PC speakers as well). You can use a PC and audio software, such as Audacity to generate a test signal. However, the signal is needed to be filtered first, as this to avoid the aliasing effect when the signal gets sampled. This method is to eliminate any… Continue reading

Hacking Your E-Bike is Just A Piece of Cake!

You have an old-fashioned exercise bike that can’t show up any data when you’re peddling and exercise with it? You wish to make a little modification on it with a multi-meter connected to cables out of the exercise bike? Oh well, it’s time to have some fun with your exercise bike now… First thing first, find one cable from the front “wheel”, where it’s a cable that going up to the “computer”. Differential the handlebar sensors and the pulse meter, which the pulse meter works with reading the change in resistance of your skin. Then, you’re hooking the multi-meter to the cable from the wheel. You can set your connection to beep, when there was a connection detected by the multi-meter. You must make sure that both of them are beep, either you’re moving the pedals or the wheel is moving. After that, you cut the wire in two and hook those up to the Arduino. Remember to solder the largest resistor, which you can find in the electronic scrap box on one of the cables. Continue reading

Enlightening Your Life with Biophionitos

What if I tell you, that you can have a virtual pet (not the online one) and you don’t need to spend a dime for the feeding, would you mind to have one? Well, let’s meet this Biophionitos, which it is a reflection on the virtual creative processes and an inspirational DIY project (Your child will love this one for sure). The main objective of the Biophionitos is to create artificial life using the Zootropes idea. Thus, you can easily draw a virtual animal or even use this as a physical animation too. This Biophionitos stuff enables you to compose a limited series of simple polygons. In the final stage, you will get a round shape with sixteen sequences of the animals, which can be printed and inserted in a phenakistoscop. There are four basic modes for this Biophionitos and there are feed, play, hug and light. All of the four modes almost using the same components, which as: Arduino Board (except the EMI board for light mode ) DC Motor 9-12V 22 uF capacitor 1K ohm resistor (it needs… Continue reading

Expand Your Creativity Horizon Starting with the Servo Motor Today

Servomotor is one of the most common electronic components, and you can control the servomotor position by only using the value returned from analog sensor. Servos also the easiest way to get you started with a microcontroller related with motion. Those components you needed are: Breadboard 22-AWG hookup wire Arduino microcontroller board 10K ohm resistors Flex sensors, and of course RC Servomotor Ok, let’s start the project. Firstly, you need to connect power and ground on the breadboard to power and ground from the microcontroller. Use the 5V and any of the ground connections on the Arduino module (Please refer the above figure). Continue reading

Have a Nice Drive with MPGuino

Do you know how can this MPGuino service you? MPGuino is a part of the OpenGauge instrumentation tool, which was created for the efficiency of instrumentation of all sorts. MPGuino is a Miles Per Gallon gauge for fuel injected vehicles, which is based on the arduino platform. Furthermore, the extra circuitry in MPGuino is for monitoring the fuel injectors and the speed sensor in the vehicle. Those parts that we needed: Two 5.1v zener diodes One 2n3906 PNP Transistor One 100 ohm resistor One 2.7k resistor Two 100k resistors Three tactile switches One freeduino arduino clone One LCD There are eight screens for this project, which: Continue reading
