Thank you for posting this video. I know it was some time ago. The library seems to eliminate (or rather hide away) most of the mind-boggling PID code (phew!) Your experiment seems to be most of what I am trying to achieve. (I will be exchanging the Pot for a distance sensor and I will need some way of homing at the start) Unfortunately I was not able to get hold of the 'PinChangeInt'* library. It doesn't seem to be available now in that I can't find it in the 'manage libraries' section(or am I wrong) therefore I commented it out and just used pins 2 & 3 for the interrupt pins (instead of 2 and 8) Sadly it does nothing, I get no motor movement at all. If the library *is available and necessary would you send a link please? Many thanks for reading

I guess you could use Nico Hood 's PinChangeInterrupt library: github.com/NicoHood/PinChangeInterrupt . Then use this: "attachPCINT(encodPinB1, encoder, FALLING);" Check his example, you have to change the include too of course. I don't have the circuit here to test but you should be able to figure it out.

Oh my god. Do you do repairs for others? I have a later model (slightly larger) Veglia clock in my Peugeot 404, wich has the same contact problem. This would be a perfect solution to get the clock ticking again.

@raydike Жыл бұрын

The later model clocks (the big round ones) don't have a contact, they work through induction (ATO patent) with a single transistor. They have a very fine wire coil, difficult to modify. Sometimes you can get them running again by adjusting the coil to magnet gap and adjusting the play in the movement bearings. The Veglia ones can have a broken plastic gear, then it is end of story.

why interrupts are needed when implementing PID on uC?

@keesreedijk7613 4 жыл бұрын

It is to keep the timing constant. Otherwise if you do something else in the main loop it influences the running of your motor, especially with speed control. For the encoder interrupts are needed anyway to keep correct track of position.

In theory yes but you will need a motor with an encoder and a beefier H-bridge. I don't think you need feedback, just a couple of end switches and a strong enough motor will do. Or a linear actuator. Best keep it simple.

Go step by step. First test the motor and H bridge by sending a PWM signal to it. If that works see if there is a signal from the encoder. An oscilloscope helps. You can also use serial commands to monitor signals.

This is great! I have been looking for DC-Closed Loop Position control for ESP chip familyn and this is the closest yet. I am trying to use something like this for all of my home automation projects but I need position based on encoder count. Having a preset count value, I would be able to control everything from mini blinds to pocket doors. There is nothing on the internet that can do this as far as I can tell. If your system could be implemented with Misan Dc control system, which I believe is used with GRBL cnc, it would be a dream. If you ever feel like building the most diversified control system on the net, please implement your system with encoder count position, and PID(to add accel and decel for smooth operation) to an ESP-32 or ESP8266 base. I guarantee it will be the hottest system out here. ;-) Thank you VERY much for sharing this great project.

@@raydike so the PID loop is controlling speed not position, as in if you tell it to have zero speed it tries to hold its position. Position is simply kept track of independent of the PID loop? Code would look like: if position < 100 , PID speed = 10, else PID speed = 0. This is interesting as other PID implementations are trying to use the position value for the PID loop which doesn't seem to work very well...
