    Importance of positive feedback from admin

    Hi Guys, I'm really glad you have all found the circuits here useful and see potential with this community. I also see that potential but unfortunately things have changed for me since I started the site. I can no longer put in the time I would like too and at the moment I usually just come by...

    Welcome to the forum!

    Dad, I have full permission to use the circuits thank you. Talking Electronics is fragmented and hard to follow for a beginner, the information is detailed in some places but not others. I've enhanced and modified many of the circuits, I've added text, better images, parts lists and videos...

    Up/Down Fading LED

    Hi Don, Yes, you are absolutely correct. To slow the fading rate, increase the value of the 33k resistor. Kind regards, Admin

    4 led chaser circuit

    Are you connecting the LED's to the correct pin numbers and not to the output numbers? The diagram above shows the pin numbers and in circuit wizard it shows the output numbers. For example the first led should be connected to output 0 in circuit wizard. If that doesn't help take a...

    What cable to use?

    Since the current will be very low you can you just able any cable you want. Although for 10 leds, you're more than likely looking at 11+ wires (one each for positive and at least one for negative). An idea for this would be to use Ribbon cable (like the old IDE cables within computers). It...

    Are you able to see which 4017 yenga is trying to simulate? The circuit I built uses the HCF4017B made by STMicroelectronics and it has a recommended supply voltage of 3-20v.

    Breadboard artwork - make your own circuits

    Another update. Components look clearer, added LDR, changed wire colours, fixed the bottom row of holes. This should be a relatively final version. I don't foresee many changes apart from adding components from now on. Regards, Admin
