The 74 series does not have a carry out. Posted by transgalactic in forum: That’s bringing up a problem: My parts arrive tomorrow. A little 1 amp 3. Aug 7, 4, Dash Camera Dash Cameras are becoming a very popular automotive accessory. The second moves from output 0 to 1, turning off the first transistor and turning on the second.

Dec 20, 10, 1, Sep 24, 2, No, create an account now.

I’ll have to investigate that further. You would probably also have to use the master reset with output 9. Am I reading this voltage tester wrong? The next question is what to do with the 10 74HC’s I have arriving tomorrow.


The LED used were a disappointment as viewing angle is about 30 deg. If all the lights are lit at once, my power supply won’t be strong enough to power that many devices.

The choice now is whether to go with the 74HC’s or to order some SR’s.

When it gets to the end he dies. Plus, what I really like about the push button idea is that the kids can send any chain of lights up that they want.

What’s inside of one? The second controls the transistors. Each transistor is tied to the negative lead of 10 LED’s each. When the first chases the second one holds output 0 high. I certainly have enough ‘s.

Posted by Shawn in forum: When the Ninth output goes high the 10th LED is lit.

The first commands the chase. Oct 25, This “Carry Out” command can be used as a clock input for the second. I think I’m beginning to settle down on a plan. I am desperate for this Inductor Posted by Dynaman in forum: Datassheet now I have to order SR’s.


Am I right on this superposition problem? Am I reading this code correct?

CD4017BD (datasheet for CD4017BCN) am I reading this right?

But you’d be limited to 9 outputs on the first, and up to 10 transistors to complete up to a datashedt LED string of a chase light. Oct 26, But the is sending more soldiers.

No need for any gates. One to send highs 1’s and one to set low’s 2’s. Yes, my password is: Can I send the last shift register back to the first?
