Quote of the day. Am I right on this superposition problem? I can send the single pulse to start one soldier marching up the chain. Am I reading this voltage tester wrong? I think I’m beginning to settle down on a plan.

The second controls the transistors. Do you already have an account? Every time the first carry’s out, the second one clocks to the next position.

Oct 24, Each transistor is tied to the negative lead of 10 LED’s each.

Sounds like good advice. Embedded Systems and Microcontrollers. You May Also Like: My parts arrive tomorrow.

If all the lights are lit at once, my power supply won’t be strong enough to power that many devices.

A little 1 amp 3. The choice now is whether to go with the 74HC’s or to order some SR’s. For your question about power, use high brightness LEDs and 1mA is plenty if you have a whole mess of them.


When it gets to the end he dies. Am I reading this code correct? Oct 25, Yes, my password is: But now I have to order SR’s. I’ll have to investigate that further. When the Ninth output goes high the 10th LED is lit. Aug 7, 4, I certainly have enough ‘s.

The 74 series does not have a carry out. Posted by transgalactic in forum: What’s inside of one?

The LED used were a disappointment as viewing angle is about 30 deg. The first commands the chase. No need for any gates. If so, and the kids hold the button down a long time there could be an endless stream of lit lights. You would probably also have to use the master reset with output 9. Dash Camera Dash Cameras are becoming a very popular automotive accessory.

Dec 20, 10, 1, Plus, what I really like about the push button idea is that the kids can send any chain of lights up that they want. The next question is what to do with the 10 74HC’s I have arriving tomorrow. No, create an account now. Meanwhile, the kids can keep sending more and more soldiers off to war, each dying cd4017bch the end of the string. That’s bringing up a problem: When the first dafasheet the second one holds output 0 high.

Posted by chaz in forum: Your name or email address: Sep 24, 2, But the is sending more soldiers. Oct 26, 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, The second moves from output 0 to 1, turning off the first transistor and turning on the second. I am desperate for this Inductor Posted by Dynaman in forum: Can I send the last shift register back to the first?

But you’d be limited to 9 outputs on the first, and datsaheet to 10 transistors to complete up to a 90 LED string of a chase light. This “Carry Out” command can be used as a clock input for the second. One to send highs 1’s and one to set low’s 2’s. Seems a comet tail was mentioned so here is a simple tested version for either or SR like 74HC
