I am making science lessons for middle and high school. appreciate the work you have put into this. I understand the amount of effort that goes into even a simple demo. this is a high end demo.
@@mahmudul.sghsc.ndc.baust. I don’t have access to a circuit diagram here but you should be able to work it out from the comments in the arduino program. Good luck!
Thanks for your interest. I built the controller using an Arduino Uno board. You can buy these from the Arduino company, but I got mine from AliExpress. The three potentiometers came from my own collection but you can buy them from various component vendors and AliExpress. The values are not critical. You just want to read a voltage on one of the analog inputs. These voltages are then converted to frequency, amplitude and shape of the PWM output that drives the servomotor. Good luck!
@@wimderkinderen1952 Thank you for the prompt reply! Could you give a brief idea of the wiring at the switch? Just trying to understand which wire goes to which terminal on the switches. Apologies, Im a complete novice!
@@elliotmccall1 We are in the Netherlands at the moment where I do not have access to the schematics. I will send them later. Basically, you connect the endpoints of the potentiometers to 5V and GND. The middle contacts then go to analog inputs A0, A1 and A2 of the Arduino. When you do an analog read you get a number between 0 and 1023. In the code you convert that into the parameters of a PWM output. I will send you that code as well.
@@wimderkinderen1952 Thank you. I assume the code is a variation of the below for 3 potentiometers? Not sure how to adapt the code from here though.. #include // add servo library Servo myservo; // create servo object to control a servo int potpin = 0; // analog pin used to connect the potentiometer int val; // variable to read the value from the analog pin void setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object } void loop() { val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023) val = map(val, 0, 1023, 0, 180); // scale it to use it with the servo (value between 0 and 180) myservo.write(val); // sets the servo position according to the scaled value delay(15); // waits for the servo to get there }
Hello Mr Wim I’m a fresh master student My studies are related to this kind of devices that you have demonstrated I’m myself dreaming about building a similar one Could you please help me? How can I contact you via mail or whatsapp or whatever you want? Thanks for sharing your information ♥️

Thanks!
Very nice demonstrations! I'm currently experimenting with surface ripples at audio frequencies in a similar tank.
sir could you show me how to design the waveheight sensor? , I'm very interested in using it on my project
Can you send me the code for arduino to control the servo please
I have uploaded the code here: github.com/Godefridus/Arduino/blob/master/Waveservo_v1.ino
@@wimderkinderen1952 brother i need one more help, please show me the connection diagram
I mean circuit diagram

Could you kindly confirm where you bought the 3-knob controller from? Thank you!

@UC11Zj-Tn0HXYJM0iBcSkhqQ Evening! If you could kindly share you code that would be super helpful! Thank you!
he sounds like Peter Griffin 🤣
That poor servo is like why couldn’t I have ended up in a airplane or something.
