I am afraid I am new to controlling motors with an arduino and so need help with pretty much everything, as there does not seem to be a tutorial which I can find online for wiring up an arduino uno with a linear actuator.
1. How do I wire up my linear actuator to my arduino uno? (Do I need any extra components for the circuit? resistors etc...)
2. How do I control my actuator, what code do I use? I need to be able to turn off for a certain amount of time then turn on for a certain amount of time, extending and retracting fully each time.
3. Eventually I need to control around 8 of these motors with the arduino, is this possible and what would I need circuit-wise in order for this to work?
Sorry for the total novice status here, any help would be much appreciated and if someone would like to write a tutorial on the topic I would be much obliged!
1. I have an SN75441ONE (4 channel Half-H bridge driver) at home, is this ok to use to make the circuit? can be found here: http://www.alldatasheet.com/datasheet-pdf/pdf/28616/TI/SN754410NE.html
2. I am confused as to what the circuit should look like, would it be similar to this image (see image attached) of a unipolar steeper circuit with a h-bridge? Please can you explain to me in complete lamens terms exactly how the circuit goes together? It would be mega useful to have a Fritzig diagram if at all possible because I am very new to all this and am finding most things quite tricky!
3. How do you decide on a 'properly sized heatsink'? can you point me to a place that sells these and the kinds which I may want to buy?
4. As I am struggling with the very basics I think I will be at a complete loss as to how the code works, can you point me in the direction of a code which I can use to control the motor, so that it extends fully and retracts fully, how would this work? Is it similar to the stepper commands to change the devices direction? Would something like the cods on this page work?
