Arduino Prototyping Outputs #85: Servos
Рет қаралды 353
4 жыл бұрынServos are just geared motors with a feedback loop. The trick is how you interpret the feedback and control the DC motor. Arduino makes it simple with the built-in library for servos.

Thanks, I made a code that combines dimming led, potentiometer and servo (as an indicator for voltage) but the problem is tha my led turns on when brightness gets to 255 it act like digitalWrite not analogWrite............ also the servo keeping on going back and forth...the code worked perfectly when I made it for dimming led only without the servo but when I included the servo both of them began to act strange any solution?

Without seeing the code, it could be a couple of things. Make sure the analog read is working fine (potentiometer input), then use that value to control the LED and servo. May want to use the "map" function to get the values you want. Also, make sure you have the servo and the LED on dedicated PWM pins. (this is most likely the issue, but again without seeing the code, schematic, and actual Arduino it's hard to diagnose. Good luck! Hope that helps.

@@MarcdeVinck I did every thing you said already and I made it no line ending too so my servo won't make that issue but I still got that problem
