RS-485 module for Arduino (MAX485 ) RS-485 module for Arduino (MAX485 ) Click photo above for details, then hover over upper right for more photos. This module interfaces an Arduino or similar microcomputer to RS-485. RS485 is used for Serial Communications over longer distances than direct RS232 or TTL, and supports multiple units on the same bus (Multi-Drop). Multiple Units can be connected to the same RS-485 wiring. LED Cube 8x8x8 At first glance this project might seem like an overly complex and daunting task. However, we are dealing with digital electronics here, so everything is either on or off! I've been doing electronics for a long time, and for years i struggled with analog circuits.
Water Sensor Node: Arduino + Atlas Scientific pH & Conductivity Sensors + Water Temp Sensor (but before I begin…I’ve had a hard time getting a post out recently. I am in the middle of the most amazing course offered by Contextual Electronics on learning how to build a PCB. Each day brings on a lot more to learn. How to Debug C Program using gdb in 6 Simple Steps Earlier we discussed the basics of how to write and compile a C program with C Hello World Program. In this article, let us discuss how to debug a c program using gdb debugger in 6 simple steps. Write a sample C program with errors for debugging purpose To learn C program debugging, let us create the following C program that calculates and prints the factorial of a number. However this C program contains some errors in it for our debugging purpose. $ cc factorial.c $ .

More than 15 different styles of logo template settings to choose from. Every single effect, style, color and texture can be managed and edited to fit your design needs. RS485 Shield I bought an A4WD (w/o electronics) a couple years ago and have experimented with Xbee RF modules for communication both directly to the Sabertooth motor controller, as well as through an Arduino. I used C# to write multi-button window panels to control the drive motors. Other than testing sensors and servos, I never got to the point of including any of them in the motor drive program. But things have progressed quickly since purchasing EZ-Robot's EZ-B Microcontroller. It comes with EZ-Builder software that already has just about any control panel a person would want included for use in its own script language. It also comes with SDK's for those who eventually want to write their own C# or VB programs.
Build a Programmable LED Cube By Ari Dubinsky and Brad Eckert Product Marketing Assistants LED cubes rely on an optical phenomenon called persistence of vision or POV. If you flash an LED really fast, the image stays on your retina for a little while after the LED turns off. By flashing each layer of the cube one after another really fast, it gives the illusion of a 3D image, this is also called multiplexing. The LED cube is made up of columns and layers. Each of the 16 (anode) columns and the 4 (cathode) layers are connected to the controller board with a separate wire, and can be controlled individually.
Water Quality Sensor Developed during the Water Hackathon on March 23-25 in New York City, the water quality sensor is a multipurpose tool for collecting data remotely. This tool is rapidly changing and is being used as part of the on going research initiative called DontFlush.Me This tool consists of an Arduino microcontroller, a set of water quality sensors, and a network connection module. As currently developed this tool uses a GSM based cellular module to send data via SMS. For this design a custom arduino shield was created.
