5K

80k
160k

Why do you need those resistor values in a DAC?

Right. Breadboards are great for beginners to play and learn. That's main purpose of them. Professionals will find parasitics of breadboards and jumper wires limiting. Tho my usual approach of quick weekend prototype (if any) - use stm32 blue pill module together with prototype circuit board on perfboard/manhattan/custom_PCBa, use breadboard as carrier and interconnect for modules. If I need some faster signal between MCU on bluepill and prototype circuit - use soldered wire or TP or coax, maybe even remove corresponding DIP pin on bluepill. Hint: get more than single bluepill/arduino and acompanying breadboard. You may have multiple ideas in parallel ;)

That can be made from three nominals: 5k is 2x10k in parallel.
Then 20k in parallel ( it is 10k).
Then 20k.
Then 20k in series.
Then 160k in parallel.
Then 160k.
Then 160k in series.
So we'll need only three popular values: 10k, 20k and 160k. Some of them exist in E24, some in E48, some in E96, and all are in E192.

For SMD people its easy to advice something like that.

It's no harder with through hole. You could have fixed it easily by now.
