newbe help with schematic to breadboard

Hello all,
I would like a schematic to breadboard tutorial with clear pictures and explanation for an American traffic light system, light duration times are not that important to me, Red stays on for say approx 1 minute then goes immediately to green, stays on say a minute, then goes to yellow, for say 15 seconds, as warning, then back to red then repeat all over again.

I found many for the UK traffic lights and got confused transferring to breadboard.

I am new to electronics, it's a hobby for me. I am not clear on how to go from schematic to breadboard, making the connections, with the wires. I get confused.

Can anyone help me understand how to hookup the wire to the breadboard just by looking at the schematic.

I would like to use these components and here is the schematic too. See attachment

• 1x NE555 IC
• 1x CD4017 counter IC
• 1x 10uF Capacitor
• 1x 0.1uF Capacitor
• 3x LEDs (Red, Yellow/Orange, Green)
• 3x 100 ohm Resistors
• 2x 100K Resistors
• 1x 22K Resistor
• 6x IN4007 or 1n4148 Diodes

 

Thanks I will keep trying

 

Thanks but way over my head

 

Do you have a schematic of such a circuit?

Changing the circuit to do what you want will take

8 diodes instead of 6
1 - 1K ohm resistor instead of 3 100 ohm
1 - 150K resistor instead of 2 100K
1 - 47 uF capacitor instead of 1 10 uF

Because of the way the 4017 works, you need only one current limiting resistor to protect all of the LEDs. However, 100 ohms is way too small. The 4017 can source only 1 or 2 mA at 5 V. That is why I changed the value to 1K.

 

Thank you Bluejets,
You are correct. I finally did figure it out looking at some less complicated schematics. Then I went back to my traffic light schematic.
I was confused on jumper wires and on where a node stops or starts.
Anyway the circuit I did is for a english UK stoplight system. AnalogKid said I deeded the following to make a US system traffic lighr

Don't worry about the 555 changes just yet. Download the 4017 datasheet and try to rework the schematic for your pattern requirements.

Do you happen to know how to create this US traffic signal? Do you have a schematic for me?

Thanks for any help.

I asked analogkid did not get a response for a schematic will try again.

 

Hello AK,
I figured out my schematic thank you for your help.
Can you please send me a schematic of what you said I needed for a uS trafic signal?

Thank You

 

This is the original UK traffic light schematic that I figured out how to transfer to my breadboard. You said I need more diodes to make it US traffic system.plus other resistors etc. Please send me a schematic of that
thank you

Thank You much

 

Here is the UK schematic of traffic light system with my explanation of what went through my thought process. Please tell me what you think.

 

Here is my working breadboard of UK traffic light system

 

Thanks I have those jumpers too
