Haha- I heard "shouldn't be touching your face" which is something you pretty much never heard before the very beginning of the COVID pandemic and then heard "cold and flu season" and was like... wait a second, and then looked at the date. March 17 2020-which was that 2 week period when it was on so many people's minds but so many people were like "ssshhh don't talk about it- it's weird."
I wonder if someone can help me, I need a basic servo that can move at least a quarter inch or a little less, it really doesn’t matter the exact measurement, the moment I push on my remote control. I already know how to connect a remote control but I just need to know if I’m doing this correctly, what I do is I connect one of the three wires to one side of a 9 V battery in the moment the other wires touched the other side of the naval battery, the server gets a little surge of electricity and it moves exactly the way I like it to move but I wonder if I’m doing this correctly, if I may damage the unit and if there is a better way, thank you in advance.
i have a problem i want a servo motor to operate in 2 different speeds with 2 diffrent clicks on button for example normal 120 degree rotation speed at single click and fast 120 degree rotation at double click using on off tactile switch using a cr123a battery.all these using a pcb or arduino in the most smallest space is it possible?
Create a variable for the switch so that its 15 when off and 5-10 when on, then replace the 15 mil delay of the servo you want to speed up with that variable.
I'm working on a project where I need to press a small lever to release a hidden 2" x 5" drawer, but the space is limited. A servo seemed like a great solution, but for my application, I'm trying to make it so if power is applied, actuate the servo (to press the lever). So far in researching and from what you're saying I need to have some sort of controller in place though. Do you know of any options where I can just have the servo arm move, say, 90 degrees when power is applied, and then go back to center when power is removed?
you could do it with an arduino microcontroller, they are super easy to program and have a built in usb port, but if you want it to be smaller you could use an attiny85 or attiny10 microcontroller. If thats still too big you can lookup some tutorials on "555 timer servo driver" circuits and that can also do what you are asking, but may require some electrical trickery to get it to go to 90 degrees specifically. As for returning to the zero point, when power is removed a servo essentially goes limp, if that works for you then congratulations! Its going to be easy, otherwise, the device may have to stay on to hold your lever at the correct position
The internet is good for some people but is very dangerous for others. I'm not trying to ridicule you, but I think you should take a break from it. So, let's say the earth is not round. What would you get out of that knowledge? Would it change your life in a positive way? We have more serious issues to focus on.@@flat-earther
