ECE385F Parts List (Lab 2, etc.)
For Lab 2
- 1 x 74LS02
- 2 x 74LS138
- 1 x 74LS373 (you may want a second one for future labs)
- 1 x 74LS244
- 8 x LED or 1 x >=8 position LED (ie. bar graph display)
(if you want to have some fun, you could get some
high brightness LEDs (http://www.misty.com/~don/led.html)
- 16 x 250 Ohm to 1000 Ohm resistors (240 ohm o.k.)
- 2 x 4 position or 1 x 8 position DIP switch
check that the above 74LS... are LS, else not good for computer drive
(make sure you get what you ask for)
250 ohms or more (why?):
Calculation of resistance value...
but some voltage dropped across LED itself...
