PrevNext The breadboard MintDuino is a classic project in and of itself, and has been used as the brain of previous Weekend Projects, notably the Repeat After Me game. However, for this build we want to transfer it to perfboard so it'll fit snugly in the mint tin and the armband sleeve.Follow these instructions to transfer the MintDuino from breadboard to perfboard, with one minor exception: don't solder the green LED to the perfboard. You'll replace this component with jumper wires connecting to your 5 red LEDs on the lid (see Steps 9–13). Step #16: Close it up! Push the lid back into the hinges and close it.

Favorited Favorite 13 Introduction Breadboards are one of the most fundamental pieces when learning how to build circuits. In this tutorial, you will learn a little bit about what breadboards are, why they are called breadboards, and how to use one.
Once you are done you should have a basic understanding of how breadboards work and be able to build a basic circuit on a breadboard. Suggested Reading Here are some tutorials and concepts you may want to explore before learning about breadboards: History If you wanted to build a circuit prior to the 1960s, chances are you would have used a technique called wire-wrap. A wire-wrap circuit (image courtesy of Wikipedia user Wikinaut) What’s in a Name?
When you picture a breadboard in your head, you may envision a big piece of wood and a large loaf of freshly baked bread. Bread on a breadboard So why do we call this electronic “circuit builder” a breadboard? Why Use Breadboards? As mentioned, you don’t always want the circuit you build to be permanent.

Lessons Menu: Lesson 5 Hardware: Computer / Laptop or Netbook Arduino MicrocontrollerUSB to Serial Adapter (if your microcontroller does not have a USB port)Appropriate USB cable (Arduino boards draw power from the USB port – no batteries yet) Standard servo motor (current consumption <50mA)Pin headers / cables Controlling a servo motor directly from the Arduino is quite easy. However, a servo motor may require significantly more current than the Arduino can provide.
The following example uses a standard sized servo (without any load) powered directly from the Arduino via USB. Connect the black wire from the servo to the GND pin on the ArduinoConnect the red wire from the servo to the +5V pin on the ArduinoConnect the yellow or white wire from the servo to a digital pin on the Arduino Alternatively, you can plug the servo’s wire into three adjacent pins, and set the pin connected to the red lead to “HIGH” and the pin connected to the black lead to “LOW”.

Using the LilyPad LilyTwinkle board Skill Level: Beginner by Dia | September 27, 2012 | 10 comments Twinkle, Twinkle, Little LED The LilyPad LilyTwinkle and LilyTiny boards are a great stepping stone between simple circuits and Arduino circuits.
Both boards will allow you to practice building microcontroller circuits without requiring that you provide your own code. Additionally, these are significantly less expensive than a LilyPad Arduino board, so if the effect you're looking for is relatively simple, the Tiny boards can make your project simpler and cheaper. Requirements Here's all the parts you'll need to follow along: The Tiny boards, much like traditional Arduino boards, take power from a power supply and then regulate what other connected devices it goes to. *Before we start, I want to discuss, just briefly, the difference between the micro LEDs and the regular ones.

VirtualWire Library, for very cheap wireless communication. VirtualWire, by Mike McCauley (PDF), helps you use very inexpensive wireless radio modules.
Download: VirtualWire.zip(version 1.15 - Teensy 3.0 support & minor improvements added) Very low cost RF modules require specially formatted data, with sync patterns, equal balance of 0 and 1 bits, and error checking. VirtualWire provides all of these features, allowing for best performance from very cheap radio circuits. Hardware Requirements VirtualWire requires RF modules.
In these photos, a 315 MHz RF Link Kit sold by Seeed Depot ($4.90) was used. These low cost modules are very simple. Transmitters usually have only a single data pin, which activate the RF output when high. VirtualWire uses Timer1, which means some PWM pins which require Timer1 will not work. Basic Usage VirtualWire works somewhat differently than most Arduino libraries. Configuration Functions vw_set_tx_pin(transmit_pin) Configure the transmit pin. Vw_set_rx_pin(receive_pin) Configure the receive pin, Default is pin 11. RF Modules. Arduino Hacks. How to make an Arduino from scratch. INTRODUCTION : Question what to make,how to make,but make you must ... After scrolling,searching,drooling over tons of Arduino tutorials..from making an led cube, to automating your home, giving life to a robot or making arduino powered drones... you, like me, must have felt that sudden urge as soon as you stumble upon an inspiring arduino tutorial, "Gosh,Wish I had one of these" or better still "I want to make one of these, Right Now!
" and as soon as that feeling hits your head, your eyes start scurrying the required parts list and you see that name : ARDUINO : 25 Dollars and the cost of your project seems to skyrocket in many cases if other electronics are not as pricey( Yup, 25 dollars might be next to nothing for some, but yeah it is something!) And of course if the other parts are pricey,you need to burn a hole in your pocket anyway...Kachang! And what's more heartbreaking(Believe me, its true!) Make stuff.

Components Arduino related from amazon.com: Bike Turn Signal & Brake Light Handlebars -Use Arduino for Projects.
This project was inspired by a very cool kickstarter called Helios Bars. Essentially what this project does, is put an arduino, LEDs, and buttons into your bike handlebars. The LEDs can be used as turn signals, brake lights, or display ambient colors while riding. It’s fun, cheap, and a good introductory to LEDs and arduino. The coolest thing though is that the project can be completely enclosed in the handlebars and even waterproofed!
This is because the Arduino Micro will fit inside handlebars with an inner diameter of 0.7 inches or greater! It is also a cheap project with a cost of around $30-$40 to buy everything. The best way I can explain it is by showing it, SO CHECK IT OUT BELOW! Step 1: Parts List Major Components in Project To modify your handlebars this project uses a ‘kit’, all the pieces of which can be bought at a place like Radioshack. Parts:Arduino Micro - You could also use Arduino Uno or any others, but they would have to be externally mounted to the bike. Many Arduino Projects -Use Arduino for Projects. Let’s Make It Inaugural Episode – Let’s Make It – Episode 1 This is our very first episode of Let’s Make It.
In this episode we introduce ourselves and talk a little about what is coming up. Hint: It is Arduino, Raspberry Pie, PIC Chips, Circuit Design and PC Board Manufacturing. Fun stuff! For the sample code, show notes, contact information and many more videos, visit the show page at Introducing the Arduino – Let’s Make It – Ep In this, our 2nd episode of this new show we take a look at the Arduino and everything it can do. Adding Buttons To Our Arduino Project – Let’s Make It – Episode 3 In this episode we pick up where we left off last week and add in a breadboard with some buttons to show how the Arduino can take input from the outside using something as simple as a button. We also cover what button bounce is and some features that are built into the Arduino that will pull a pin to high so that you do not need a resistor in the button circuit.
Kaleidoscope with Arduino and RGB LED strips | Cool Arduino. I present a new Arduino project: a Kaleidoscope (or something similar), with a list of the simplest materials. You can see the result in the video. It can be used as decoration in a living room or as decoration for the baby's crib. The baby will be surprised ... Very relaxing if it accompanied with Chill out music . Thanks to the advent of addressable LED strips, is extremely simple (and cheap) to create projects with multiple RGB LEDs. These strips contain small RGB leds.
Each led is accompanied by a WS2812 circuit capable of controlling an RGB LED with 256 levels for each color. The assembly is very simple, just a strip of LEDs 60 leds / m cut into 12 parts of 5 leds each, and mounted on a piece of PVC (forex). A sheet of opal Plexiglas handles diffuse the light of the LEDs and enhance the effect. The circuit is so simple it does not need schema ... just an output pin of the Arduino connected to the input of the strips (DI), and of course, the power supply (GND and 5V).
