- A tutorial on how to make a servo motor controller & tester circuit using 555 timer IC and a few other components. This circuit allows us to manually drive/control any servo motor by pressing buttons or by turning knob of a potentiometer.
Link to the project page and circuit diagram: elonics.org/servo-motor-contr...
Components Required
* 555 Timer IC
* Servo Motor
* 1 PN Diode (I used 1N4148)
* 2 Momentary Push Button Switches
* Resistors: 220K, 56K, 10K
* Capacitor: 100nF
* Breadboard
* Few Breadboard Connectors
* (5-9)V Power Supply (Adapt to Servo voltage)
Note: If you wish to control the servo using potentiometer, use a 50K resistor in series with a 1K resistor instead of 56K, 10K resistors and push button switches. Refer to the circuit below for the exact arrangement.

Great video!
Nice circuit
Super Bro👏
Can you make the respons litle bit faster, because i feel it's delayed when using potentiometer
Can we use this one circuit to control two servos separately?
How can we slow down the rotation of the servo motor when we press the buttons???
It's not working please help me.
will this setup work with a servo that rotates 360-degrees with the buttons
What resistor value for 90degree angle?? Thanks
Who is voltage of zener diode is used in this project?
Which resistor can we use instead of 56k ohm ?
This is One of the best electronics Channel on RUclips
Can servo turn in 3 different directions for 3 different inputs ?
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
Is there a Schematic for the potenciometer
how to control servo using op amp?
Please send the circuit diagram
Diagram please
Can it be done automatically
круто
How to auto spin this?
Bro i did the same connection but its only turning one direction pls help me i have to submit this tmr 😢
Are resistors required or not
cd4017 you use neN i saw servo me neN no work p only work what is n and p.
Battery capacity ?
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?
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:(
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.
How did you make the 56k resistor work?
Subtitles would be fine.
