Dash Camera Dash Cameras are becoming a very popular automotive accessory.

The 74 series vd4017bcn not have a carry out. I think I’m beginning to settle down on a plan. I am desperate for this Inductor Posted by Dynaman in forum: The LED used were a disappointment as viewing angle is about 30 deg.

That’s bringing up a problem: Each transistor is tied to the negative lead of 10 LED’s each. I certainly have enough ‘s.

For your question about power, use high brightness LEDs and 1mA is plenty if you have a whole mess of them. When the Ninth output goes high the 10th LED is lit.


Every time the first carry’s out, the second one clocks to the next position. Do you already have an account? What’s inside of one? Datasehet by transgalactic in forum: Sounds like good advice. No, create an account now. Quote of the day. The first commands the chase. I can send the single pulse to start one soldier marching up the chain.

Sep 24, 2, Your name or email address: When the first completes the count, on the next clock pulse the first sends a “Carry Out” signal which acts like a clock input to the second. Nov 23, 8, 6, Am I right on this superposition problem? My parts arrive tomorrow. When the first chases the second one holds output 0 high. Oct 24, The choice now is whether to go with the 74HC’s or to order dattasheet SR’s.

Plus, what I dagasheet like about the push button idea is that the kids can send any chain of lights up that they want. You May Also Like: Aug 7, 4, Dec 20, 10, 1, Embedded Systems and Microcontrollers. One to send highs 1’s and one to set low’s 2’s. This “Carry Out” command can be used as a clock input for the second. Am I reading this code correct? Posted by Shawn in forum: Seems a comet tail was mentioned so here is a simple tested version for either or SR like 74HC The second moves from output 0 to 1, turning off the first transistor and turning on the second.


Am I reading this voltage tester wrong?

CDBCN Fairchild 16P/DIP

But you’d be limited to 9 outputs on the first, and up to 10 transistors to complete up to a 90 LED string of a chase light. Meanwhile, the kids can keep datadheet more and more soldiers off to war, each dying at the end of the string. The second controls the transistors. There is probably a way to use the last output from the first counter to act like a carry out.

When it gets to the end he dies.
