Proyek arduino dengan sensor pir light. On the top left corner it also has a trigger pin setup which can be used to make the module work in two different modes. One is the “H” mode and the other is the “I” mode.In “H” mode the output pin Dout will go high (3.3V) when a person is detected within range and goes low after a particular time (time is set by potentiometer).

This is for my car; I previously had a blitzsafe unit that plugged into my oem aux input and outputted to an 8-pin mini-din. From here, I had an iphone4 connector to 8-pin mini din. This both charged my phone and allowed me to play my music through the aux port of the headunit.
I've gotten an iphone6, and now I need a new solution (iphone cord has changed). I've decided to prevent this in the future and go bluetooth. I have this unit en route:Now as you can see, I need a power source (USB) and 3.5mm jack to make this bluetooth unit work.
The simple solution is to order this cable, which will go off my blitzsafe unit's 8-pin mini-din and give me exactly that:However, 15$ is a bit steep, I'm cheap, and I have a DIY nature. I figure I could simply hard wire a usb cord and 3.5mm cord directly to my 8-pin mini din (after I cut the end off).
What I need to know is which pins are used? I've located pinouts of all 3 components but it is still not crystal clear to me. I am finding conflicting pinouts for the 8-pin mini-din.USB has Vcc (+5v), Data-, Data+, GND3.5mm has a Left(+), Right(+), and GNDBasically, I am looking for a definitive pinout of a 8-pin mini-din, and where to connect the 7 wires listed above.In the end, I bet I will just spend 15$ for that adapter, but my curiousity has got the best of me at this point. Thanks in advance.
5 Pin Din Connector To Usb Adapter
I have a wonderful IBM Model M keyboard, which has the best key action of all keyboards I ever used. The problem is it has the big round 5-pin DIN connector used in AT PCs.I have some PS/2 to USB converters, and I know they are very 'moody', often only working with keyboards they were shipped with, and sometimes not even that. I do have DIN to PS/2 connector, but - expectably - the double conversion it doesn't work with these PS/2 to USB converters.How can I use my 'retro' keyboard with modern PCs without PS/2?
The PS/2 to USB 'converters' that come with some keyboards only work if the keyboard itself supports both PS/2 and USB protocols (which are totally different), and the converter just provides an alternative plug by re-wiring the pins. That's why they only work with the keyboard they were shipped with. I don't know of a single XT/AT keyboard that supports USB, which is why any attempt to use those 'rewiring converters' will fail. You really need a converter with its own microcontroller, which are never shipped together with a keyboard.–Jul 20 '16 at 15:24. There are two aspects to this. The cable for the physical connection and the driver for the communications protocol.I suspect with adaptor upon adaptor you are either losing voltage and therefore connectivity or the protocol is getting confused.Your core problem will lie in the communications protocols.
There is a defined USB to which peripherals such as keyboards must comply. The old IBM keyboard clearly doesn't.
If you use Mac OS X 10.6.8 or later,. Sirena tervis 3000 pdf printable. Windows.Mac.
The host computer will interrogate a USB device using a Setup Token Packet. A USB keyboard will respond, the XT keyboard will not.PS/2 to USB converters, and other USB converters, usually have a small embedded processor that handles the protocol.So:Writing a USB driver on your new PC to bypass the USB protocol is probably impossible as the USB ports are likely to be driven by a dedicated chip.Cutting the PS/2 connector off your USB-PS/2 adaptor and soldering the wires directly to the DIN plug - in the hope that the voltage loss is reduced and so the flakiness you describe goes away is very risky. Also, the protocol chip may be in the PS/2 plug!Although the pinouts are not too bad. The IBM DIN and PS/2 sockets have pins as below:1: Clock2: Data3: Reserved (in practice, usually a reset line)4: Ground5: +5VI would suggest: Use a USB-RS232 adaptor and wire the DIN plug to a DB25 or DB9 RS232.
The keyboard will then appear to the PC as being on a standard COM port. You then write a keyboard driver for your new PC that converts the data stream from the old keyboard.
The easiest (PnP) approach is definely using two adapters. The first one should be a USB to PS/2 (miniDIN) adapter; This one needs to be an active adapter, such as this one:Avoid using weird smaller adapters like the one below - they probably won't work because they're designed for motherboards that have a PS/2 host, which allows them to be passive (motherboard will be in charge of changing D+ and D- from the USB port to Clock and Data signal from PS/2).
If you have one lying around, you can always try it - your PC will be fine even if the keyboard won't work with this one.The second adapter should be a passive one; You can either make one yourself ( working schematic on the last picture) or buy one like the picture below online.One last thing; If you're going to make an adapter yourself, you should not connect the same colored cables from the DIN cable to the same colored cables from the miniDIN cable; Always verify what cables you're connecting to what pins and double check if the polarization is OK (ie. That you haven't connected + from the miniDIN to a - on the DIN).
