Anatomy The three most important types of digital signals that come out of a digital camera are the data lines, the pixel clock, and the enable lines.
XBEES. Understanding Digital Camera Sensors. A digital camera uses an array of millions of tiny light cavities or "photosites" to record an image.
When you press your camera's shutter button and the exposure begins, each of these is uncovered to collect and store photons. Once the exposure finishes, the camera closes each of these photosites, and then tries to assess how many photons fell into each. The relative quantity of photons in each cavity are then sorted into various intensity levels, whose precision is determined by bit depth (0 - 255 for an 8-bit image). Cavity Array Light Cavities However, the above illustration would only create grayscale images, since these cavities are unable to distinguish how much they have of each color. Color Filter Array Photosites with Color Filters A Bayer array consists of alternating rows of red-green and green-blue filters.

Pin Description Index References to EIA Publications Back to CableEye® Home Page What is EIA232? In the early 1960s, a standards committee, today known as the Electronic Industries Association, developed a common interface standard for data communications equipment. Over the 40+ years since this standard was developed, the Electronic Industries Association published three modifications, the most recent being the EIA232F standard introduced in 1997. Likely Problems when Using an EIA232 Interface Next Topic | Previous Topic | TOC During this 40-year-long, rapidly evolving period in electronics, manufacturers adopted simplified versions of this interface for applications that were impossible to envision in the 1960s.

The UART, or Universal Asynchronous Receiver / Transmitter, is a feature of your microcontroller useful for communicating serial data (text, numbers, etc.) to your PC. The device changes incoming parallel information (within the microcontroller/PC) to serial data which can be sent on a communication line. Adding UART functionality is extremely useful for robotics. With the UART, you can add an LCD, bootloading, bluetooth wireless, make a datalogger, debug code, test sensors, and much more! Understanding the UART could be complicated, so I filtered out the useless information and present to you only the useful need-to-know details in an easy to understand way . . . What is RS232, EIA-232, TTL, serial, and USB? RS232 RS232 is the old standard and is starting to become obsolete. Back in the day circuits were noisy, lacking filters and robust algorithms, etc.
EIA232F Today signal transmission systems are much more robust, meaning a +/-12V signal is unnecessary. MO-RX3400.pdf (application/pdf Object) MO-SAWR.pdf (application/pdf Object) RF Link 4800bps Receiver - 315MHz. Replacement: None.
We are looking for a new supplier for these, but don't have a replacement yet. This page is for reference only. Description: Sold as a receiver only. This receiver type is good for data rates up to 4800bps and will only work with the 315MHz transmitter. Multiple 315MHz receivers can listen to one 315MHz transmitter. This wireless data is the easiest to use, lowest cost RF link we have ever seen! We have used these modules extensively and have been very impressed with their ease of use and direct interface to an MCU.
This receiver has a sensitivity of 3uV. Features: 315 MHz Operation 500 Ft. Documents: RF Link Transmitter - 315MHz. Running TX433 and RX433 RF modules with AVR microcontrollers. Sometimes in embedded design you may want to go wireless. Might be you will want to log various readings of remotely placed sensors, or simply build a remote control for robot or car alarm system. Radio communications between two AVR microcontrollers can be easy when specialized modules are used. Lets try to run very well known RF modules TX433 and RX433 that (or similar) can be found almost in every electronics shop and pair of them cost about ~15 bucks. Transmitter and receiver modules are tuned to work correctly at 433.92MHz. Transmitter can be powered from 3 to 12V power supply while receiver accepts 5V. 5V is common for AVR microcontrollers so no problems with interfacing.
Implementing RF Modules. A while ago I bought an RF link pair(which consists of one RF transmitter and one RF receiver) for Sparkfun for implementation in one of my client's products.
I wanted to try out RF because it was cheaper than bluetooth. And by cheaper I mean A LOT cheaper. A bluetooth module would have cost me around $40 and a single RF receiver costs around $4.
