For my hobby I want to get my simple elevator to move up and down using one mometary push button. At the bottom and top of the elevator shaft I have reed contacts and on the lift itself a magnet. I have an Arduino Uno, an LN293D motor shield, DC 6 volt transmission motor and as said 2 reed contact…

I must add some info as the solution is not what I have written in my last post. Changing the chip resulted in a temporary solving. The real reason was a bad contact between the UNO and the Motor Shield. The voltage on this pcb dropped sometimes from about 5 volt to close to 4 volt and that made …

What do you have (hardware and software) so far?

There are elevators that are pulled from the top and there are ones pushed from the bottom. Which will your be? Paul

Thanks Bob for taking this on at 69.... I am 65 so can sympathise especially with the high expectation of GKs! Some things to take into account at this system design stage: Switch debouncing The limit switches and even the PB switch will need to be debounced to avoid unwanted behaviour. Debounci…

Further to my post on switch debounce and ways to deal with it. I now believe you can avoid having to anything for the following reasons: I note you are using reed switches. I was assuming they were mechanical. Reed switches should not bounce due to the hysteris of magnets i.e. the turn on moment …

Hello Bob The solution for this elevator task can be either coded in C or in C++. My basic design for this elevator task is done by using C++. C++ is more comfortable by using a none class declaration of objects and services = methods to process these objects. That sounds crazy a little bit, but t…

I am away today and will answer questions as soon as I am back. Found afterwards a mistake in my describtion, so I must correct it. The elevator itself I have from somebody no longer working with it, he build it. The Arduino Uno lost it's programm and I must make a new one with some more features…

All info I received today I will study and see if it helps me further. But as asked by some you and as promised by me, here some more info. This is the hardware: Arduino UNO R3 MK Electronics Motor Control Shield L293D (4 motors / 2 servo-stepper (spare one is from Iduino)) DC - 6V / 50RPM mot…

How sure are you that the Arduino is the problem? It is of course quite possible that it is, but I'd be more suspicious about the wiring and other components at the start of the investigation. The code you will need if you have to replace it should not be too tricky to construct - especially if you…

This web site has a pretty good list of elevator parts and names and how they work: PArts list. Paul
