DIY The Arduino with 8×8 LED Matrix Today!

You have seen the Arduino with 8×8 LED matrixes at some of the electronic expos, but you’re always wondered if only the project will involve a big and tough programming code? Well, if you have the urge to DIY an Arduino with 8×8 LED matrix, then there is nothing to stop you by. This Arduino with 8×8 LED matrix is driven by a MAX7219 IC, where you can easily find it out at the local electronic shop! It’s controlled through an Arduino microcontroller board. Beside that, you should prepare a custom PCB and make sure it can be used to tidy up all the wires connecting the LED matrix and the IC. Since it is comes with a separate 12V power supply, this mean you don’t even need to drain everything from the Arduino board all by you! In this project, you have to make sure that you’re and identify the four important wires, which are necessary to control the MAX7219 IC. Those wires are: The Data wire; The Clock wire; The Latch/Load wire; The Ground wire. Both of the… Continue reading

Ladies and Gentlemen – Let’s Meet The Brand New StickDuino!

The technology of Arduino grows in the leaps and boundaries, and you can see many latest Arduino related products every single day. Have you ever thought you can simply stick the Arduino board into the USB port of your desktop/laptop? Well, it might be seen impossible in the very beginning, but guess what? Now, some genius inventor has released the brand new USB stick sized Arduino clone and they named it “StickDuino”! Yep, you didn’t see it wrongly. This StickDuino has the size almost of your index finger’s length. It’s a very compact Arduino compatible tool that you can slide it into your pocket and carry it wherever you want to go with it! This StickDuino is well designed with the fully hardware compatible feature and it’s uses all the SMD components. Since this project involves many SMT passive components, thus assembling a StickDuino is not an easy task for those new home hobbyists, which has no experiences with the SMT soldering! Furthermore, you’ll find that the board is feature with at least two or more analog inputs than the… Continue reading

Protoduino – The Trimmer and Slimmer Arduino/ATMEGA8

Although the Arduino is already a very compact and small-sized microcontroller, but you still wish it to become even trimmer or slimmer? Oh well, you wish is granted today, as there is a new trimmer/slimmer standalone prototype board, which specially designed for the Arduino/ATMEGA8 and its named “Protoduino”. Or, you want to take your Arduino project that you wish to take one step over the temporary breadboard, but you’re too lazy to create a new PCB, then this Protoduino might help you solve up the hassle. This Protoduino board is well designed for the easy customization, which the trace can be cut for giving an additional flexibility. Beside that, you can also trim away those unwanted parts of the board, as you want. Some of the great features for this Protoduino are: The input voltage (Vin): 7.5-9VDC The On-board power supply output: 5 VDC at 100mA max Clock speed: 16 MHz Resistor network: 150 ohm, 100mW max per element As this is a kit, you still need to do some basic soldering to assemble it. In addition, you cannot program… 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

Is Time for Your Very First Persistence of Vision (POV) in Arduino Version

Do you know most of the cartoons are create based on this Persistence of Vision method? This Persistence of vision is the common phenomenon of the eye, which in nanoseconds of exposure to an image that result in milliseconds of reaction from your retina to the optic nerves. The persistence of vision is always being compared with the related phenomena of beta movement and phi movement. In the point of view for POV, your eye/brain system functions as a motion detectors rather than camera. That’s why this POV has widely being used in the Film, video, cartoon animation and optical toys production. You main goal for today is to mount the POV in a bike wheel and it will display a fascinating views while you ride on it. Continue reading

DIY a Top-Drawer SD Card Read/Write with Arduino For Yourself!

Do you wish to have a small and portable SD Card Read/Write with Arduino, but it’s somewhat costly to buy it from the RadioShack? Well, then just Do It Yourself and you definitely can cut off the budget cost for sure. For today project, you must refer to the below schematic diagram. As you’ve noticed that the above schematic uses some resistors in a voltage divider, and its main point is to bring down the Arduino 5V logic to the SD Cards 3v3 logic. By this way, all the outgoing signals from the Arduino will constantly dropped to 3v3. When the 3v3 is above logic 1 for the Arduino, then the incoming signals to the Arduino are fined. In other hand, the 3v3 voltage supply from the decimelia was normally used to supply power to the SD Card. After the above step, make sure to desolder an SD Card socket from a broken memory card reader, and solder those pins onto the bottom. In addition, you have to ensure that the thermistor is perfectly connected to analog1 with some resistors… Continue reading
