First I am not experienced in IC circuitry but have an understanding of different gates and basic electronics. Need some help on making a circuit that can take a place of a rotart 5 position switch. The requirements is power relays to make the 5 different positions and also have a 7 segment display showing current switch position 1 to 5 using an up and down momentary buttons. I have been playing with Yenka software and made a circuit that of course works the way I need it to. The single LEDs on the 4028 should actually be a SPST relay.
Maybe I am over thinking this.
In the Yenka software when powered it jumps from 0 to 1 with the use of the 74132 IC of pin Q0 on the 4028 chip. So this will display 1 on the 7 segment display and sends the Q1 to output on the 4028 chip. I press the Up button and it displays 2 and and Q2 output is active on chip 4028. Now pressing up again and again till it hits what would be displayed as the number 6 on the display will again power the 74132 gates to cause it to go back 1 back to 5.
Now I have prototype this circuit on a breadboard with a regulated 5v power supply but it will not change up or down pressing either up or down button. I made it simply as in Test Image #1 and not used any of the 74132 gates, 74266 gates or the 4511 and 4028 chip. Just connected leds to the out Q1,Q2 ,Q4, and Q8 on the 74192 and press up or down buttons and no change to the outputs. Here is where I am at a lost.
I have no problem starting from scratch again but as to the result is the following. Power on and start on #1 display and activate #1 relay. I would try a PIC circuit but have no programming knowledge on that. Display 1 to 5 and activate the correct relay for the output.
Sequence:
Power up and display 1 on the 7 segment display and activate 1 of the 5 relays.
Press UP button and display 2 on the 7 segment display and activate the next relay.
Same UP till you hit display 5 on the 7 segment display.
Press UP again will result a return back to 5 on the Display and its connected relay.
Press Down button will be the oppisite but once you Hit 1 on the display and press Down again will cause it to return to 1 on the display and its connected relay.
If someone can make me a circuit that works I be extremely grateful for it and pay well for it.
Thank you to all that can help me out.
