Plus, what I really like about the push button idea is that the kids can send any chain of lights up that they want.

I am desperate for this Inductor Posted by Dynaman in forum: Oct 24, Dec 20, 10, 1, One to send highs 1’s and one to set low’s 2’s. There is probably a way to use datasheet last output from the first counter to act like a carry out.

Sep 24, 2, If c4d017bcn the lights are lit at once, my power supply won’t be strong enough to power that many devices. No need for any gates.


My parts arrive tomorrow. But you’d be limited to 9 outputs on the first, and up to 10 transistors to dattasheet up to a 90 LED string of a chase light. Quote of the day. Every time the first carry’s out, the second one clocks to the next position.

I certainly have enough ‘s. Posted by Shawn in forum: What’s inside of one? Oct 25, But now I have to order SR’s.

Am I right on this superposition problem? Meanwhile, the kids can keep sending more and more soldiers off to war, each dying at cd4017gcn end of the string. Dash Camera Dash Cameras are becoming a very popular automotive accessory. Posted by transgalactic in forum: Can I send the last shift register back to the first?

Do you already have an account?

Each transistor is tied to the negative lead of 10 LED’s each. I can send the single pulse to start one soldier marching up the chain. For your question dattasheet power, use high brightness LEDs and 1mA is plenty if you have a whole mess of them.

You would probably also cd4017bcb to use the master reset with output 9. Am I reading this code correct? A little 1 amp 3. Yes, my password is: The second controls the transistors. Embedded Systems and Microcontrollers. The first commands the chase. Ccd4017bcn think I’m beginning to settle down on a plan. The next question is what to do with the 10 74HC’s I have arriving tomorrow.


When it gets to the end he dies. 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.

But the is sending more soldiers. Sounds like good advice. The LED used were a disappointment as viewing angle is about 30 deg. I’ll have to investigate that further.

When the first chases the second one holds output 0 high. Your name or email address: Oct 26, No, create an account now. Am I reading this voltage tester wrong? The choice now is whether to go with the 74HC’s or to order some SR’s. Posted by chaz in forum: Aug 7, 4,
