Added on August 12, 2009, 6:33 pmI think parallel port is all but dead. Why do you want to use parallel port? Do you already have some tools to control the parallel port with?
I don't know if the kind of programmable IC you're looking for exists.
You can make your own simple audio player using micro-controllers like PIC, but you'll need to write the whole program, not just the song you wanted to play.

e-fatty: it was mention in the link that hdd Vss is only +3.3v, max232 chip is rated for 4.5-5.5v (typ. 5v). You need to take a look at max3221, and the application note, usually it will show you few circuit example to how to connect the chip.

tgrrr: Honestly, I don't know what I'm looking for. Camera module usually transmit in i2c, with other information available by the reading the rest of the pins. I read the datasheet, seems like need to write down a lot of code if I were to use uC. In case there is already a better solution... like a specific chip or module My target is to at least able to read, say 50x50 line out of the entire resolution (VGA or higher). I'm working on a project similar to line-following robot, but can't use the typical close-range IR to scan the line, due to terrain constraint. VGA would worth a try. Let me know if you have other ideas

fantasy1989: to spin a motor the other way, just reverse the polarity (+ve connect to -ve, and -ve connect to +ve). If you want better control, can try H-bridge circuit. H-bridge has the advantage of speed control and brake. To design H-bridge circuit, first need to know what motor you use, and what is the motor load (what the motor is use for). You can read up in wikipedia to understand the basic of H-bridge. Let us know what the motor is used for, we'll suggest a better way to that. Cheers

This sensor look kinda expensive, got water-prove somemore, want to install outdoor is it? Maybe you can try Jalan Pasar, try those shop that sell light, alarm. They may not have the specific model, but if you tell them what is your application, usually they can recommend you the alternative. But this only apply for manufactured parts

HB2E-DC5V, pin 3 and 14 are your input, give it a 5v supply and the relay will engage.
When engage, pin 8 and 2 will short, (aka connected), and pin 9 and 15 will short also.
When disengage, pin 8 and 1 will short, and pin 9 and 16 will short.
Usually this type of relay are used when you have 3 different circuit that run on different voltage supply. i.e., your switching supply run on 5v, and you need to use it to switch on a 12v circuit (pin 8 and 2, or 1) and another 24v circuit (pin 9 and 15, or 16).

What type of IR sensor? For what application?

Which circuit? The IR sensor or the communication with PC? Frankly, I have neither. it depends on which IR sensor, environment, controller.... Assuming fantasy1989 already had the circuit, I'm just stating the possibility of interfacing it with PC via parallel port.

hi guys,

where can i purchase electronics stuff online? had the link last time but lost it. Malaysian site that is.

fantasy1989: parallel port respond on +5v. For your case, if your switching is slow and time critical, you can use a transistor circuit, or op-amp circuit. If it is time-critical, then you need to get those TTL chip. Be careful when playing with parallel port, if you apply the wrong voltage or current, it may smoke your motherboard!

rokiroad: I found the solution already, in fact had my PCB board done. Speaker amplification, try this. Do look up for LM386 datasheet and application note for more info.
