Use a new type of circuit part, and integrated chip (IC) called the 555 timer as we wire up alternating red and blue lights in this breadboard circuit building tutorial.
Take our entire Breadboard Circuits Class as we build simple circuits, begin to use chips like the 555 timer, and even program in Arduino!

  • Excellent tutorial! I’m glad I’m not the only person who doesn’t know why pin 6 and pin 2 are connected. It just seems like a part of life 😀

    • this is to trigger the flashing effect that alternate between the led polarities, thats why blue pos(+ or anode) and blue neg (- or cathode) is inverted to the red + and - .

  • Thank you for this easy to follow 'monkey see, monkey do' tutorial, it's my first time using a 555 timer and literally brightened my day when it all worked, I appreciate you sharing your knowledge :)

  • The rst(reset) pin of the 555 timer is active low, meaning when you connect the rst(pin 4) to ground(-supply voltage) the 555 is locked into the reset mode. Generally one connects pin 4 to +supply voltage(pin 8) to make certain it won't drift low with electronic noise present in the environment. Also the datasheet recommends a small value capacitor, 0.1 uF, or 100 nF, between pin 5 and ground if you won't require the CTRL function, for the same reason. Neither is required in most instances for a standard 555 IC, but becomes more important for the low power CD7555 CMOS IC. Otherwise well done.

  • I want to do a traffic light situation but with like several rows of it being led lights green, then yellow then red. How would I go about this and I also need to use timed relays.

  • Most versions of this circuit connect the capacitor to positive supply not pin 3. And you don't have the capacitor connected through a resistor to pin 7 to discharge.

  • You connected to pin 7 instead of pin 6 threshold in one of the steps

  • This is fantastic. The only missing detail is to note that the Red and Blue LEDs operate on different voltages. I was using two reds and got wonky results. Red operates on about 2-3 volts, blue is about 5 volts. 100uf capacitor was a really slow blink, but 10uf was an easy swap.

    • You can simple connect 2 more led parallel to the other ones

  • Your videos are great and the little animations thing you added was a very big move but I think you should also le us see the schematic representation of the connections you are doing so we can understand clearly. Some of us are struggling with Basic Electronic course. Thank you😊

    • 1k( which include red line) other one is 10k, and cap value all on you, 100uF works well. Cap valuse is just about the led lighting tine
