Hello! Well, I have set out to have analogue inputs to one PICAXE, convert to servo variables, do a little math, and send the results to another PICAXE via a pair of half-duplex RS-485 transceivers. The second PICAXE sends those variables to a AXE033 for now, need to wait on purchasing more...

Is there a way to compare two separate variables, for example, if b0>128 and b1>128 then....?

I have been browsing this forum looking for information on how to code some mathematics. I would like to solve something like; (b0/255)*150 I understand Picaxe does not support fractions (and brackets (manual 2, page 25)), I just can not figure this out.

I tried to get my wife on board for getting a sail boat, but she's not interest. She would go for an old lobster boat converted to a cruiser, works for me! I tried figuring out how to reference a bit of a byte but really couldn't find anything, so I just tried something in AXEpad, syntax...

I would like to have only two chips communication with the serial commands. To keep things simple, I would like to have one discrete input into one chip, transmit a variable to the second one, and turn on/off a LED. I see the examples in the manual but I'm still unsure. Can I have the first...

Thinking about getting the Axe110 but I have a question, can I have the data logger record the sensor values or time stamp on an event change not time interval? Hopefully I make sense.

Specs; Test Forward Current 350mA, Power Dissipation 1.1W, Forward Voltage 3.0 Min, 3.3 Avg, and 3.6 Max. I was blinded by my frustration and that formula looked extremely familiar. I=(Vs-Vf)/R, 0.35=(5V-3.5V)/R, R=(1.5V)/.35, R=4.28ohms So if I wanted to use two of these LEDs, I would have...

I'm troubled with trying to figure out how I'm going to power a 2.8W LED that requires a max of 3.6V and 350mA. I have on my breadboard a small relay which I figure I would use to switch the LED. I have been trying to figure out a voltage divider but I'm not getting anywhere and I really don't...

I have a simple routine that checks a temp then turns on/off a relay but I'm trying to have a momentary switch that latches a different pin high or low. I was thinking that an interrupt would work but it seems to not work on the PICAXE. I'm struggling with that interrupt routine, any...

1st, my experience is low. I want to switch a 12v .2A computer fan with a PicAxe, I just need direction regarding what component would I look at to switch the power to the 12 volt fan? Jarubell

Been a while, but I see free time in my future so I'm looking at a small project to monitor my fuel oil tank. I'm would like to find some magnitic reed switches that I could stack and install a magnet epoxyed to the level indicator inside the plastic lens. I'm hoping that that would give me a...

I'm starting to play with an Axe033 and I believe I have successfully connected it to a 20X2 PICAXE. Following the literature that came with it, loaded the test program (Hello!123), it worked. Than successfully loaded the sample program to load predefined messages, Player 1 and 2 as per...

Well, I was trying to solder a header on a AXE033 with little experience and just as I was getting the hang of it, I soldered across to the next pin. So, i'm looking for ideas ho to fix this?

Looking at getting a AXE033B and learn to play with but what else should I get with it? Oh, what microprocessors would I get for it? James I guess I'm looking to getting the AXE033B and processor up and running with some basic inputs and have some type of HMI

I was told that getting two chips talking to each other is fun, so, here I go but I need direction, where do I start. I have a 08M and 20X2.
