💬 Servo Control Actuator

[Duncan Pullen]

I had issues with this sketch only doing what looked like 90° of motion when using a slider.
Turned out, it was doing 100°.
To rectify change the myservo.write line to:
myservo.write(SERVO_MAX + (SERVO_MIN-SERVO_MAX)/100 * 1.8 * val); // sets the servo position 0-180

how, what and is it possible to control 2 servo's, on pin 3 and 4 of 1 arduino?

@albert-p thanks for reporting.
Which board are you using?
How did you install the servo lib? From which source?

hello. I have a problem with this sketch. After restart, the servo moves only once, then the whole system locks.

@Andrzej what does the node's debug output say?

This post is deleted!

nothing, node is blocked, i think this is due to servos time measurement in sketch, but when i replace servo with led, led blinks. I'm using MYSController

@Andrzej Maybe power related - what power supply are you using and are you connecting servo to arduio for it's power?

[Andrzej]

@skywatch, wow, you were right, I remembered such a basic thing, thank you for your help
