hello
I have this code , and i went to change from using button to 3 Capacitive Touch
sensor with these options ;
1st Switch:
- Gives an option of 1tsp scale (5ml)
2nd Switch:
- Gives an option of 1tbsp scale (15ml)
3rd Switch: (Cup Scale)
This have 3 options inside of it,
- 1/4 Cup (62.5 ml)
- 1/2 Cup (125 ml)
- 1 Cup (250 ml)
how can I build it ?
