audioguru Posted April 26, 2004 Report Share Posted April 26, 2004 On the schematic, R3 should connect to the LED anodes, but not to T1 as shown. Quote Link to comment Share on other sites More sharing options...
Guest Posted April 26, 2004 Report Share Posted April 26, 2004 Thanks for showing me the error. I must have by mistake done it theother way.Good obsevation.Can it be changed in anyway?Are you going to build it?Please tell me how it works.

audioguru Posted April 26, 2004 Author Report Share Posted April 26, 2004 On your schematic, I can't see where the diodes connect to.I built a similar Knightrider circuit that uses only LEDs and it clearly shows the diodes:http://www.electronics-lab.com/projects/motor_light/035/index.htmlPlease compare its diodes to yours.

Guest Posted April 26, 2004 Report Share Posted April 26, 2004 i have darkened the points in the schematic diagram where the diodes connect.I have made this schematic diagram on PAINTBRUSH. Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 26, 2004 Author Report Share Posted April 26, 2004 Your 4017 pin numbers do not seem to be in the proper order for the lights to be sequential. For example, 4017 pin3 should feed the 1st light, but you have pin1, pin 4 should feed the 3rd light, but you have pin 2 etc. Don't you have them mixed-up? And the diodes?You don't talk about the switch but I think that it is used to shorten the sequence, but position 4 seems to light only one light continuously instead of 5 lights. All other switch positions seem OK. Please check your switch position 4. What is the regulator used for? With your well-filtered 12V unregulated, the parts don't need it.

Guest Posted April 27, 2004 Report Share Posted April 27, 2004 Okay.I fix the circuit again and go through it again.Thanks for pointing out the mistakes.You are good. Quote Link to comment Share on other sites More sharing options...

Guest Posted April 28, 2004 Report Share Posted April 28, 2004 It was the first time i designed a circuit on my thoughts and half of the circuit matched with yours.Good experiance for me.THANKS!!!!!!!!!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
