One to send highs 1’s and one to set low’s 2’s. But now I have to order SR’s. My parts arrive tomorrow. Dash Camera Dash Cameras are becoming a very popular automotive accessory. For your question about power, use high brightness LEDs and 1mA is plenty if you have a whole mess of them. 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. Aug 7, 4, The first commands the chase.

Sounds like good advice. Can I send the last shift register back to the first? Plus, what I really like about the push button idea is that the kids datasheet send any chain of lights up that they want. Posted by Shawn in forum: Every time the first carry’s out, the second one clocks to the next position.


Seems a comet tail was mentioned so here is a simple tested cf4017bcn for either or SR like 74HC Nov 23, 8, 6, You May Also Like: I am desperate for this Inductor Posted by Dynaman in forum: Meanwhile, the kids can keep sending more and more soldiers off to war, each dying at the end of the string.

Decade Counter/Divider With 10 Decoded Outputs . Divide-by-8 Counter/Divider With 8 Decoded Outputs

No need for any gates. Posted by transgalactic in forum: I think I’m beginning to settle down on a plan. I certainly have enough ‘s. The LED used were a disappointment as viewing angle cd4017bdn about 30 deg. Posted by chaz in forum: If all the lights are lit at once, my power supply won’t be strong enough to power that many devices.

Am I right on this superposition problem? Oct 26, No, create an account now. You would probably also have to use the master reset with fd4017bcn 9. But the is sending more soldiers. The 74 series does not have a carry out. I’ll have to investigate that further. If so, and the kids hold the button down a long time there could be an endless stream of lit lights.


Sep 24, 2, The choice now is whether to go with the 74HC’s or to order some SR’s. What’s inside of one?

Do you already have an account?

Each transistor is tied to the negative lead of 10 LED’s each. Dec 20, 10, 1, When the first chases the second one holds output 0 high. There is probably a way to use the last output from the first counter to act like a carry out.

CDBD (datasheet for CDBCN) am I reading this right? | Page 3 | All About Circuits

That’s bringing up a problem: Am I reading this voltage tester wrong? Yes, my password is: When it gets to the end he dies.

Quote of the day. When the Ninth output goes high the 10th LED is lit. Am I reading this code correct? Cs4017bcn second moves from output 0 to 1, turning off the first transistor and turning on the second.
