Hello
To start I would like you all to know that I haven’t done any designing for almost 30 years, so I am almost a newbie and hope you will understand if I seem ignorant. I am trying to make a special counter for a workout machine, this is just a circuit to count reps and sets that I do, so I don’t have to count mentally and forget where I am at. I have been searching for a while now and can’t seem to find what I need, so I need your help please.
I have a cable multi-station that can do this, but I would like to also be able to have it on my other cable machine that is not digital.
The way it should work…
Before I would begin I would enter the number of reps and the number of sets required for a routine. Ex. 3 sets of 15 reps
Then when I would pull on the cable and start to release 1 rep would be done and the reps display would go down 1 to 14 and so on till I got to 0, where a tone would sound saying I had finished 1 set, where I would rest. The display would then indicate
Ex. 2 sets of 15 reps
And so on till sets were 0 and reps also 0
I would like to recreate this if possible, but I have not been able to remember how or find anything on the net that can get me started, so I call upon you for help.
Maybe someone knows of an IC that may have theses characteristics, or an idea of one that may help me.
The following or the characteristics of this unit and a pic of the console …

The following or the characteristics of this unit and a pic of the console …
- When entering the first rep it also adds 1 to the sets and vice versa.
- The adjustment can only go down to 1, not 0, only the input pulse (weight movement sensor) can make the reps or sets count down to zero.
- When the reps counter hits zero it returns to the number it started at when the input pulse (weight movement sensor) began, unless the sets counter is at zero then it remains at zero.
- Sounds
- 1 beep for sets and reps going up or down
- 5 beeps when a set is completed
- 1 buzzer when trying to lower the sets or reps below 1
- Sleep mode, this is asking a lot I know, this console shuts off automatically when not used after 5 mins.
