I am an electronics engineering student who recently started working on Arduino. As part of my efforts to wake up on time, I decided that I should make an automatic water spray alarm clock. I have all the raw material ready (Spray Bottle, Arduino Uno, MG995 servo, external power supply for servo). I also have the test code ready. The only thing I am having trouble is how my servo should pull the spray handle.
For this interface, my options are:
- Nylon fishing line. It is small enough to go thru mounting holes of servo arm of servo, but not strong enough to pull the spray handle.
- Something that sticks to plastic servo arm as well as plastic spray handle, should it be a rod or a long piece of wood that can be put in place with screws? This is the part where I am stuck, as to what should I choose as the interface that sticks tightly to the servo arm and the spray handle and pushes spray handle when servo moves.
