Add Realistic Slow Motion to Servo Point Motors

I prefer servo point motors because they're cheap and reliable compared with other methods. Another benefit of servos is that with a small amount of code they can be slowed down to look more realistic.

In this video we look at two methods for coding realistic slow motion into a servo point motor.

The first method uses the delay() function and does the job, but can cause problems elsewhere.

The second method using the millis() function is slightly more complicated to setup, but allows everything to happen at the same time without delay.

If you want to know more then this guide from Adafruit is really helpful: https://learn.adafruit.com/multi-tasking-the-arduino-part-1/ditch-the-delay

These methods can be used to slow down any servo motor or even to add fade to LEDs connected to a PCA9685.

If you'd like to give this a go yourself then all the kit can be found in my Amazon shop or via the affiliate links below. Note that these are affiliate links which means the channel receives a small percentage of the sale which goes to support production, but don't worry you still get the same great price. Thanks for your support.
