Servo Release

Hey guys, I'm currently looking at getting a new system that can set of a remote control servo, I have been working with the guys at Maxbotix and they have informed me this is the sensor i need for the job, Does anybody have any clue which board would plug into both a servo and the sensors and when the sensor picks up the target so it picks up that pulse and sets a servo off.

Thanks, Connor

I will leave reading the PDF datasheet for the sensor to you. What does it say about how you connect the sensor to an Arduino?

I suspect any Arduino board would do the job. Servos are very easy to control with an Arduino.

I'm not clear from your post what you mean by remote control - what is remote from what?

It would probably help if you draw a diagram of how things are to arranged and post a photo of the diagram.


That looks like a very capable sensor, and the interface to control it looks straight forward. As I read the data sheet, if you have chosen the TTL variant then you can connect the analog distance output directly to an Arduino analog input and read the distance directly. You'd need to calibrate it to get an accurate conversion from analog level to actual distance, but the code involved is very simple and you could do it on any Arduino with a spare analog input.

Controlling a servo is also very simple and can be done on any Arduino with a spare digital output. If this is all you need it to do, you could use any Arduino that uses the same TTL voltage level as the sensor.

Thanks for the reply, i wish that made sense to me but im hopeless with this stuff, So basically it needs to be able to plug into the sensor and servo at the same time. I need to be able to program it so when the sensor picks the hurdle up at say 4m away it releases the servo. I have no clue what this TTL is i cant find it on many of the control boards, can somebody please suggest one because im terrible at this.

Any ideas are greatly appreciated.

TTL refers to the logic level voltage that the digital circuits are operating at. If you're going to connect this sensor to your Arduino via a digital connection then the Arduino and the sensor need to be using the same voltage. Most of the Arduinos operate at 5V, but there are a few that operate at 3.3V.

Can you answer my earlier questions?


Any ideas are greatly appreciated.
