555 timer as a servo controller

Schematic: http://i654.photobucket.com/albums/uu262/antipico/Servo555.png?t=1235589739

Testing a setup where a single 555 timer is used to create the signal for a modified servo motor. Two LDR-resistors work as a voltage divider/adjuster that controls the servo rotation.

Control voltage is fed to pin 5. Pin 3 is the output for servo. Decoupling operating voltage with capacitor is recommended.

@IcechickenSr you are right, like it says in the description they are ldrs. I have used this for example to keep solar cells pointed at the sun and for two wheel self-balancing bot.

how do you get the servo to spin more than 360 degrees? with the LM 555 ?

what about if i want the servo to rotate constantly ...how'd you do that :-) ?

[Antipico]

For example in this demo i can keep the servo rotating as long as i want. It's modified to rotate unlimitedly.

I thought the schematic was somewhat clear. Do you understand the meaning of each symbol?

[Tuborg2645]

There is no LDR on your schematic :)

[Antipico]

It can be replaced with anything from potentiometer to oscillating circuit. This is just a simple demo for testing and show.

If your looking for high torque cheap servos just buy those scrubbing bubbles automatic sprayers the servo in them is waterproof and very powerful!

Hello, I'm looking into building a model rocket with its ailerons controlled by a timed servo, and I can't figure out how to build the circuitry.

@mutanTV131 I'm not mean, that's just... urm... IDK what it is but it's not mean

[mutanTV131]

@idiotAREstupid im just guessing, you didn't have to be mean. A tree got burn't down

[idiotAREstupid]

@mutanTV131 No! This work with photoresistors!

[mutanTV131]

is this how a Wii controller works LOL

hello ! i like this project and i wanna build two for my first robot but i dont know wher to put these two LDRs in the schematic can you tell where? thank you!

[djdellboy]

replace the LDRs with a gyroscope and thats your segway right there ;)

[xfactor330]

You can use this as a gyro.

thank you for the schematic, it's one of very few that actually work
