Output can be confirmed with an oscilloscope. Uno R3 Arduino Comp For all your product inquiries, send us a message on our Contact Page with the Product Inquiry subject.

If you have any amazing things you want to discuss with Tinkbox, don’t hesitate to contact us:. The datasheets listed below have been obtained from various places on the Internet.

Jameco Electronics – We 74ls2n to buy most of our stuff from Jameco before they “improved” their web site. They may have absorbed Motorola’s TTL product line, or at least their tech library.

Mega R3 Arduin These will be fixed someday, maybe. Texas Instruments – TI has a large collection of datasheets online, both for current chips and for many obsolete ones. On Semiconductor – I think they are mainly a distributer of ICs, not a manufacturer. Atmel Microcontrollers For information on the Freescale microcontrollers that were used in EE up until aboutand sample code for them, click here.

They are all copyrighted by someone but we’re not going to worry about that. Skip to main content. Other Atmel microcontroller documents and links AVR microcontroller interrupt vectors – A list of the interrupt vector names for the AVR microcontrollers listed above. Many of their files are scans of pages from their printed databooks and the images come out looking pretty bad. Either way, they have a large collection of datasheets online and they are good quality.

Arduino Pro Mini Implements a 3-bit up-down binary counter with binary outputs and seven-segment display outputs. All students should read this before starting construction of your project in the lab. Newark and Mouser Electronics – These two are major suppliers to the electronics industry with very large inventories. These were originally written for the ATmegaA and should run unchanged on that processor.

These parts are not normally used in current EELx projects. However the size of the catalog sometimes make it hard to find things.

TTL Logic IC 74LS21, DIP-14

We have no experience using the program at this time but it’s probably worth checking out. Using the serial communications interface on the ATmegaP and MCJL16 microcontrollers – An explanation of the serial port and and how to use it to exchange data with other devices, along with examples of sending and receiving data over the ATmegaP and MCJL16 serial ports. These sample schematics for devices unrelated to the class projects are similar to the types of schematics that should be produced for your project.

This document discusses programming the ATmegaP but much of the information also applies to other ATmega or ATtiny microcontrollers used in the class. You can also call us at 74ld21n send us a message through our Facebook page. Arduino basics with Tinker Danica. Order Information Free shipping.

Engineered in the Philippines. S – Displays a sequence of hexadecimal numbers on a seven-segment display. Parts in stock – This is a list of most of the parts that the EE class has in stock for project construction. This is collection of documents from a variety of sources for use by the students in EE Lx.

Motorola – datasheet pdf

Modern Device – They seem to have a interesting variety of components including many datashret and related components. These devices contain two independent 4-input gates each of which performs the logic AND function. Micro – They sell a wide variety of interesting stuff.

They send out a printed catalog of over pages. Datasheets for the datsheet parts were mostly obtained from the manufacturers or from Jameco and Digi-Key where we order most of our parts.

However they do have a PDF of a pocket version of their logic data book. Some are nonLS parts that are logically compatible with 74LSxx parts, but may have problems electrically due to different fan-in and fan-out.

Powered by Rethink Tech Inc. Some of satasheet documents may not be relevant to the current semester’s project but are left here for reference purposes.

Tinkbox is currently in beta mode. S – Controls an LED with a switch. The “74LS” will find it in one of the datassheet common logic family, and the “N” says to find a standard plastic package.

It’s now more difficult to find stuff on the web site datasheeet you may be better dattasheet requesting a printed catalog or looking through the PDF version of the printed catalog.

Fairchild Semiconductor – They used to have a good collection of very presentable datasheets but 74s21n looks like most of the 74LS ones have been removed. How to Make Learning More Fun? Contact Infomation If you have any amazing things you want to discuss with Tinkbox, don’t hesitate to contact us: Most are not scanned images so if you can find these, it will be easier to read and print out.
