I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun. The total cost is only $9! Here are a few limitations to RF solution: Communications is […]
Finally, I finished reading the datasheet. It didn’t give much information about how to connect the motor controller to a micro-controller. I used the simple circuit I found from a post in Pololu’s forum: Using Dual VNH3SP30 Motor Driver with arduino @ http://forum.pololu.com/viewtopic.php?f=15&t=1923. Dual VNH2SP30 Motor Driver Carrier MD03A to Arduino Circuit Diagram I connected […]
We are three students from California College of the Arts in San Francisco in the Architecture program. This studio is called Creative Architecture Machines and is taught by Jason Johnson and Michael Shiloh. Webster is a geometric pattern weaving machine that takes inspiration from Islamic tiling, geodesic dome construction, weaving machines, and conventional 3D printers. […]
This is a funny looking clock that has that displays time on relatively large 32×16 Bi-Color LED Matrix. It includes also a countdown counter that I find very useful in many situations. Features: Date And time display Temperature display Countdown timer Buzzer notification Randomly changing colors of display Display intensity control (brightness) Aside the fact […]
This instructable was created to be entered in the Robot Challenge. If I win, the parts will of course, go into robots like this one. Notes on how to include some of the very components in the prize packages are given in the last step. I am 28, so of course, I’m not going for the […]
This Arduino project is a simple light meter using a photo-transistor. An LDR would be more appropriate but the photo-transistor is what I has spare at the time. On the other hand the photo-transistor is sensitive to infrared, so its handy for testing remote controls. The project consists of 10 red LEDs driven by 10 […]
This is my second instructable. i want to share some of the basic things i made using the arduino i am so busy lately. then i got the chance to have this spare time… inspired by my former student and a fellow co league to share this arduino based wireless automation. this automation was done […]
We can instantly open a door or control anything we can connect. It works from any iPhone, Android, or PC. After connecting something we want to control, download the free app to a PC, open a port, and control it remotely from anywhere. It’s open source so anyone can modify it to sense and control […]
Like me, you may have a few old Arduino boards or ATmega8 chips (in the boards) laying around from when you were first playing with Arduino. Those chips can still be really useful as the heart of a tiny “Minimal Arduino” setup. A normal Arduino board contains support components that make it easy to use. […]
Been seeing few DIYs on how to establish a communication between MATLAB application and Arduino that is hardwired to PC. However, I haven’t encountered anything that control Arduino via MATLAB wirelessly using the ENC28J60 compatible Ethernet shield. In this ible’, I’m going to show the simplest way to control Arduino using MATLAB wirelessly. WHAT YOU […]
