Good day to you all. I have found some problems connecting wires to 2 linear actuators and motor drivers.
Link of the source: Syncing Two Linear Actuators using an Arduino | FIRGELLI (firgelliauto.com)
so I am confused why there are 5 wires for each linear actuator and where the three wires come from.
Linear actuator used: Sumret SRA6000.
Motor driver: BTS7960

 

The five wires appear to be one pair for the motor, and the other three are a common and two L.S. conductors. ?

 

Good day to you all, i want to ask about how to modify the connection of wires based on two links below
IBT2 and arduino control DC motor/ Linear actuator (fritzing.org)
How To Control a Linear Actuator with an Arduino? | FIRGELLI (firgelliauto.com)
these only show connections for 1 motor driver and 1 linear actuator. If I duplicate the connection for the second motor driver how to write the code for it and how to synchronize the movement?
thank you

 

The set of 3 wires connect to a Linear-Resistor-Position-Sensor,
The pair of 2 Wires is for Motor-Power.

You can not use a Linear-Actuator that has
only "Limit-Switches" if You want guaranteed positional-synchronization.

If You have to ask, this project might be too advanced for You,
unless You already know how to manipulate the Code required.

This can also be accomplished with a simple Analog-Circuit and a single Potentiometer.

From the description in the link, the following statement.

" The optical encoder is a small plastic disk with 10 holes in it that is connected to the DC motor such that when the motor spins the plastic disk does too. An infrared LED is directed towards the plastic disk so that as it spins the light with either be transmitted through the holes in the optical disk or blocked by the plastic of the disk. An infrared sensor on the other side of the disk detects when the light is transmit through the hole and outputs a square wave signal. By counting the number of pulses the receiver detects we can both calculate the RPM of the motor and the distance the linear actuator has travelled. "

Sounds like a digital encoder rather than analogue.

 

My bad .......
I missed any description of the actual type of Sensor being used.
I wonder if it's an Absolute-Position-Sensor, or just a Repeating-Pulse ?

"A disk with 10 holes in it", seems to be a primitive form of slot encoder!?

 

How much precision do You require ?
An extensive explanation of what You are trying to accomplish,
and why, will get You much more useful answers.
Pictures/Drawings are even better.

Above diagram is a connection of BTS7960 motor driver to linear actuator without arduino with dc power supply 12 V and step down voltage using MP1584 link attach MEMBUAT RANGKAIAN PENGONTROL LINEAR ACTUATOR DAN MOTOR DC TANPA MICROCONTROLLER (MUDAH) - YouTube
Is this good because I just break a motor driver maybe because i done it without soldering just simple wire attachment for testing only
