Hello Everyone,
Well I have a circuit on the breadboard that I saw in the projects forum here. https://www.electro-tech-online.com/attachments/chaser-gif.57/
I ran into something interesting and was wondering about this. On the 555 chip pins 2 and 6 I jumped with a wire right over the chip that then goes off to a 2.2 uF cap to ground. If the cap was on the pin 2 side to ground VR1 would not supply a stable timing but when I moved it to the pin 6 side to ground it worked great.
I was wondering how I would go about soldering this now that I am moving to a project board.
Thanks for your help I am very new to this and find it quite enjoyable. I did modify the circuit somewhat and went with Opto's to the triacs. as well as a full bridge rectifier power supply. It works great on the breadboard when the cap was placed on the pin 6 side.
I look forward to finding out why it behaved that way, thanks in advance for you explanations!
Ted
