Well, you're right and I bought myself some extra time to find out this part of my project. You must be proud
. I'm sad because it hurts my wallet. My whole problem is I want to do everything and I mean everything, not only the Arduino, on my own which is positive but there is a negative side to it as well because I cannot concentrate on one thing at the same time. And when there is a deadline involved the stress starts building up towards the end because I need to do this, this, this, this, this and this. Oh, and this too!
But I still want to do this on my own, figuring out the Arduino and you might think: "Yeah, great you learn new stuff!" But actually it's not that good for my health. And you might think you need to plan better. I do plan but you always encounter unseen problems and you need to adjust and start over again. Resulting in that you will fall behind your planning because with this project everthing is new. Meaning, I don't know how long something will take. I'm guessing. Next time I will know and that's what it's all worth for, I agree but it's not very healthy this way.
Anyway, since I have this personality disorder wanting to do everything by myself I do have some questions about the relay and coin switch, hope you can inform me a bit.
Do I need to unhook the wires from the controller (see photo) , attach them to the arduino, let some wires go from the arduino to the controller coin switch part?
Or do I need to connect it directly at the physical switch.
I've been looking for relays and how to connect them but I can't seem to figure out which one to get. The coin, music mechanism has 12v dc. The horse itself has 220/240v AC. Don't know yet about the light and fan. I have 2 Driver Relay boards with 2 relays on it (so 4 relays). It says 5v. I have a few currents board with 20mA and 2 with 50mA.
What about transistors and/or diodes, which ones. I looked up a few tutorials and lot's of other threads and I think it's safer to use transistors but don't know much about them.
I'm being very carefull because the horse wasn't cheap and I'm afraid I will kill my horse. I want to go to the radio-shack and I was looking up this week what to buy but I just can't seem to figure out what I need and how to choose. And the guys at the radio-shack don't know much...
