Made the circuit. The momentary switch with 10 K resistor worked, the 56k did not. Put in the variable resistor and it worked. Put signal on the scope. the 10 K resistor side produced narrow pulse of duty cycle 6% and the 56K produced a duty cycle of 22%. I put a variable resistor on the "56K" side and discovered that the circuit would only "work" if the resistance was 33K or less that produced a DS of 15%. In addition, the servo switched directions at a DS of 10. Above that (up to 15%) it went one way, and below that (seemingly no DS too small) it went the other. My theory is that this is due to a difference in the servo motor and how they respond to different duty cycles. Mine will not respond or recognize a DS over 15% (with freq in the 50-60 range). Thoughts?
For a "typical" radio control hobby servo about 5% duty cycle = 0 and about 10% duty cycle = 180 at a frequency of 50hz. Duty cycles in between these values correspond to positions between these values. The data sheet (assuming there is one) will give you the specifics for your servo.
I have completely copied what you did but the servo movements are not smooth or similar to each other, can you tell me what could be issue in my case? Thanks in advance
Are these formulas for the resistor values? High Time: Th = 0.693 x (R1 + R2) x C1 = 1ms for 0deg and 2ms for 180deg Low Time: Tl = 0.693 x (R2) x C1 = 18ms Period = Th + Tl = 0.693 (R1 + 2R2) x C1 = 20ms
This is One of the best electronics Channel on UA-cam
It's not working please help me.
It's working bro ❤❤ thank you so much ❤❤

How did you make the 56k resistor work?
thanks Jeff

Bro i did the same connection but its only turning one direction pls help me i have to submit this tmr 😢
Great video!
Nice circuit
will this setup work with a servo that rotates 360-degrees with the buttons
Super Bro👏
Which resistor can we use instead of 56k ohm ?
Can you make the respons litle bit faster, because i feel it's delayed when using potentiometer
How can we slow down the rotation of the servo motor when we press the buttons???
Who is voltage of zener diode is used in this project?
Can servo turn in 3 different directions for 3 different inputs ?
Are resistors required or not
Can we use this one circuit to control two servos separately?
Do I need to use a diode? Can I use a normal diode that just works one way, or does it need to be a specific diode model?
Is there a Schematic for the potenciometer
so I hope to build this sonn. I need only 0 deg to 90 deg and, operate two servos.
What resistor value for 90degree angle?? Thanks
how to control servo using op amp?
Diagram please
Can it be done automatically
круто
Please send the circuit diagram
Battery capacity ?
cd4017 you use neN i saw servo me neN no work p only work what is n and p.
How to auto spin this?
How do we calculate the resistor values for position 0 degree and 45 degree?
Are these formulas for the resistor values?
High Time: Th = 0.693 x (R1 + R2) x C1 = 1ms for 0deg and 2ms for 180deg
Low Time: Tl = 0.693 x (R2) x C1 = 18ms
Period = Th + Tl = 0.693 (R1 + 2R2) x C1 = 20ms
not work:(
Funktioniert LEIDER NICHT , hat jemand einen Tip ????
Subtitles would be fine.
