Arduino multiple servo's the simple way 

Just by watching this video for a short time, you have helped me so so so so much with my project, thank you immensely!

To avoid the start jump that servos have when you turn on the power, try to first give 5V to signal pin, then power the servo, it worked for me.

This has been the most usefull thing I've seen on the net today; just what I was after. Many thanks.

It's nice to hear a Kiwi explaining this!

Excellent job

This is awesome! Thanks for posting it! I have been wanting to make a 3 axis Halloween Skull and now I am one step closer. Now I need to build the platform and movements. I hope to tweak your code to get the head to move loft to right, and and down and hopefully tilt. Thanks again for sharing it I greatly appreciate it.

answer to all my questions, thank you!

thanks bro, finally I found way to this, thanks a lot

Very nice. Gr8. Thanks for sharing.

Thank you thank you thank you! Froma complete novice you've helped me gain knowledge. I have some questions. I'm making an xwing and want the wings to open up and r2d2's head to swivel. I used your servo version one code and I want to add more positions. Thanks to you my servo is moving 10° and back to close but I want it to hold in the 10°position for a few seconds before it closes again, also i want it so start off slow ,speed up and slow before it gets to 10° everything i try to add more steps the the animation it doesn't work and I'm not sure why

Hello The link in the description isn't working, I loved the video and I'm hoping it'll helped further my knowledge of servo control

is there no PCA 9685 at this time ?

Thanks so much for this absolutely brilliant. You say the source code is below but it doesn't seem to be, is it still available? Thanks again

Thank you for this awesome tutorial! May I ask some beginner question here? Does it damage the servos if they hold the position for a longer time? Why I'm asking: I am about to program a robot owl, and it should ideally hold a particular position after a movement is done. If I simply detach the servos, gravity would do its job. (Your cat is so cute!!)

Very well explained Appreciate your efforts Thank you for giving us this readymade Please help not able to open link

This is so incredibly helpful!

HI. I want to program 4 to 6 servos to do stuff individually. I have a servo driver pca9685. Im trying to make something with these motors and a couple of lights and sound. I do not want batteries. I want to be able to plug this thing in the wall with only one cord not 2. Looks like though I need 2 seperate power supplies. I cant find anything online. Something I buy? A hack? Thanks

Great video, trying to get the source code but the link no longer works. Is it available from somewhere else?👍

Very well explained. Although could you explain the circuit wiring. I can assume how the servos are attached to PWM pins, but I notice a capacitor there. What is it for and how exactly is it wired, and is it essential or is it just like a protection thing

Probably a daft newbie question. I have loaded the INI file into the Arduino. Where do I add/use the servo0/1/2 CPP and servos H file ?

This would be really useful for my college project. I am unable to open those links provided in the decription.

Hey mate, I tried to get access to the code you made available but the link wouldn't work. iS there any way you could make a new link?. Cheers

I really appreciate the tutorial. I now have 4 servos wired up but I want to make it to where when i click the button then the code is executed and then returned to home position before executing the rotation. Can you help me?

This is so helpful, my level of coding is copy paste and play with values, is there any way to get this code. I am making a prop raven

i use that servo code for my automated blinds :)

is there a source for the code, the link does not work?

Would you be kind enough to upload the code again please as the link does not work. thank you

Hello I tried to look at your source code but it is a blank screen I know this is an old video but I just found your page and I did use a proxy

the link for the code seems down.. possible to check it please

Can I get the code for this, it looks like the link is no longer valid. Thanks.

Hi sir, can you make a video for your updated code ? I figured out there is a button in pin 2 and my test failed cause I think I made some mistakes.

Thank you so much, that’s what I needed.

Would this code work with an Arduino uno? I'm trying to move a robotic arm with 6 servos with an arduino uno, I have an external power supply that provides 7.5 V but I keep getting these weird glitches where only 2 of the 6 servos move. I believe it's because my code has them moving at the same time, however this code allows them to move simultaneously right?

Thanks for posting this and for sharing the code. When I validate I get this error message though: error: 'TICK_TIME' was not declared in this scope

been searching the internet for days and still havnt found an answer. I want to make several servos move with if statements. like, if a servo position is at 70, i want another servo to go to 30....if that makes sense....anyone have any answers?

i miss when ardiuno was 3 dollars!

WHICH SERVO IS THIS

Quick question, can anyone share the link to review the code or the code itself? The link doesnt work, Thanks!

So from what i can understand, splitting the code in cpp files makes it possible to run multiple functions simultaneously. Am i right??

I think the link is dead.

Let me preface this by saying I am not a coder. I an a one time user at the copy and paste level of knowledge. I found this script for moving model railroad turnout servos. But it is only for one turnout. I have 6 on my layout. Would you be so kind as to give me the code to have this work for 6 turnouts and for each turnout, instead of only having 2 position indicator LEDs, I would like to have 2 other LEDS that would be used for a signal light. They would change with when the position LEDs change. Thank you for the time, help and patience. Gary G #include // original nscaler control of 1 turnout. // constant variables used to set servo angles, in degrees const int straight = 90; const int divergent = 110; // constant variables holding the ids of the pins we are using const int divergent_led = 6; const int straight_led = 7; const int buttonpin = 8; const int servopin = 9; // servo movement step delay, in milliseconds const int step_delay = 70; // create a servo object Servo myservo; // global variables to store servo position int pos = straight; // current int old_pos = pos; // previous void setup() { // set the mode for the digital pins in use pinMode(buttonpin, INPUT); pinMode(straight_led, OUTPUT); pinMode(divergent_led, OUTPUT); // setup the servo myservo.attach(servopin); // attach to the servo on pin 9 myservo.write(pos); // set the initial servo position // set initial led states digitalWrite(straight_led, HIGH); digitalWrite(divergent_led, LOW); } void loop() { // start each iteration of the loop by reading the button // if the button is pressed (reads HIGH), move the servo int button_state = digitalRead(buttonpin); if(button_state == HIGH){ // turn off the lit led if(pos == straight){ digitalWrite(straight_led, LOW); } else { digitalWrite(divergent_led, LOW); } old_pos = pos; // save the current position // Toggle the position to the opposite value pos = pos == straight ? divergent: straight; // Move the servo to its new position if(old_pos < pos){ // if the new angle is higher // increment the servo position from oldpos to pos for(int i = old_pos + 1; i = pos; i--){ myservo.write(i); // write the next position to the servo delay(step_delay); // wait } } // turn on the appropriate LED. if(pos == straight){ digitalWrite(straight_led, HIGH); } else { digitalWrite(divergent_led, HIGH); } } }// end of loop

the link is not working

this is the simple way???
