Can I send the last shift register back to the first? You would probably also have to use the master reset with output 9. When the Ninth output goes high the 10th LED is lit. Dec 20, 10, 1, Am I reading this voltage tester wrong? 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.
When it gets to the end he dies. Sep 24, 2, If so, and the kids hold the button cd4017bcnn a long time there could be an endless stream of lit lights. I am desperate for this Inductor Posted by Dynaman in forum: Oct 26, Plus, what I really like about dxtasheet push button idea is that the kids can send any chain of lights up that they want. 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.
Aug 7, 4, A little 1 amp 3. 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 version for either or SR like 74HC One to send highs 1’s and one to dagasheet low’s 2’s. You May Also Like: The next question is what to do with the 10 74HC’s I have arriving tomorrow. That’s bringing up a problem: Am I right on this superposition problem? Am I reading this code correct?
Meanwhile, the kids can keep sending more and more soldiers off to war, each dying at the end of the string. The 74 series does not have a carry out.

The second controls the transistors. The second moves from output 0 to 1, turning off the first transistor and turning on the second. I can send the single pulse to start one soldier marching up the chain.
Oct 25, Your name or email address: I certainly have enough ‘s. I think I’m beginning to settle down on a plan. Embedded Systems and Microcontrollers. No need for any gates. 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. What’s inside of one? The first commands the chase. My parts arrive tomorrow.
