I recently purchased the MustA01a usonic sensor, but can't get any sort of differing voltage reading from the output pin ( I get a continuous 3.8mV ).... I've...
Hi dears, I am new to this group. If anyone of you have worked on PIC microcontroller, 17c42a in Extended microcontroller mode using peripheral interrupts....
OK I am trying to power a MUST01A 40 ft range sensor off of a 12 volt DC battery. I created a small circuit of two resistors both 180 ohms each in series to...
using resisitors will not work it will interfere with peak current. Try a few diodes they will let through all the current while dropping the voltage .7 each....

OK that makes some sense. I will try the Diodes. The battery is 12v max and can produce 1.3A max. I thought the sensor could only take 30mA as it says in ...
Anyone know where I can get a MC145407 IC for the MB2325? Seems the board is using a very old chip. I was trying to find a cross- refernce part and I thought...
Go here --> http://www.unicornelectronics.com/MOTOROLA.html <-- They advertise it for 9.99. Uhoh used they ad word might get banned now lolol. Note for the...
TM, Thanks, I'll take a look at it. I would not have posted here if I hadn't first done a search. I did a search on Lycos and Google yesterday. I even did...
TM, Wow, you're right. $9.99 is a bit much for a $.10 part. I guess I do need to design a board using newer components. I was looking at redesigning 68HCxx...
Hello dear, I am sorry to be sort unwelcome guest type. I am using 17c42a microchip's microcontroller. There is no group available(the one which is-is quite...
Hi every body, Well, I'm new to the world of TJPRO. My robot works very well except for its IR detectors. In the manual, it is said that output pin of IR ...

Scott, Yes, I sent them a note the other day and waiting to hear back on it. Thanks again. I'm anxious to get my board fired up. I ran into a problem with...
Thats odd the read outs should be 86 to 120 in the configuration you describe. Since with no IR the sensor reads 86 it sounds like you hacked it properly....

Hi, I require an ultrasonic sensor with a very narrow beam which can sense a couple of cm difference from up to 2m away. The sensor will be hooked up to 5V...

Hi dear Scott,Your suggestion worked, and now I have no problem. My jumper was in an incorrect state, and you guessed right. Thank you very much.Warm...
83 to 87 is correct for the low end. The high end should be nearer 119 to 127. If you read the IR too fast, the readings will be smaller. For best readout, you...

The reason is that this groups is focused on HC11-based micros not the pic. There are probably plenty of groups discussing the pic. Try searching on google.com...

I am not sure that that is physically possible. However we have gotten quite good resolution by scanning the MUST01 back and forth. What I can say is the...
