Hello collective, I need a bit of help, I have a 10mm white led that was prewired for 12v but when I apply 12v at 200mA the resistor gets hot. Almost enough to melt the solder holding it to the LED. So, I am pretty sure I need a different resistor to make these work without meting them down...

Hello all, buntay again with a question that I am not completely sure about. Application: I have a coal bin I would like to monitor the level of. I am planning on using 10, evenly spaced, 6-30Vdc PNP capacitive prox sensors and will be powering them with 12V. Problem: I would like to use 1...

Hello friends, I need some math help, so let me set the stage. On my diesel truck I have a fuel rail pressure transducer for the trucks computer. There is a spot to add another one, now I have found an OEM transducer so everything stays safe. What I want to do is add this transducer so I can...

Ok, I have a Frequency drive for a blower motor and I would like to control it with Picaxe. Here is the datasheet on a digital pot http://che126.che.caltech.edu/11195c.pdf it is a single channel, 8 pin dip chip. How in the world do I talk to this thing? I have read virtually everything I can...

Hello all. I need a bit of help here cause i cant seem to grasp this. I would like to jump into playing with some digital pots and my question has 2 parts. It seems you can only do SPI interfacing and I really don't understand whats supposed to be going on here, can somebody break the hspiout...

Hello again all, Hopefully this question can be answered simply. I have been commissioned to retro fit a piece of equipment for my place of work due to the fact that the electronics and PLC are so out of date that the company doesnt even have the program for one even if we found a plc. Here is...

Hello all, I have been through the manual and checked over my code but I cant find my error. The manual says that a word value uses 2 byte values....ie b0+b1=w0. so wouldn't b8+b9=w4 and b10+b11= w5? here is what I am tryin to do. I have a 28x2 that is running code and I am using a 18m2 as a...

Hello Picaxe collective :) After a little break I am back into my tinkering. I have come across some surplus LCD modules. Not being the super savey techy I should be, I was wondering if these manuals could be put into layman's (picaxe) terms I can understand to make these work via 9600 baud...

Hello collective I'm back....hahaha I have a question for the mathematicians among us. I need a multiplier of 3 but every 4th entry add 1.... hard to explain so here is the code. The only thing is the b1 numbers cant change from what I have listed in code. setfreq m8 main: count c.2,3000 ,b0...

Hey all having issues with some maths. heres the setup a prox that sences 8 bolts and i need to hold a 200rpm using an output based in the "count" input. so heres what i have so far. 1 rpm = 8 bolt "counts" in 1 min, 4 bolt counts in 30 sec, 2 bolt counts in 15 seconds. running the "count"...

Hey all, I recently purchased a network module and have it working great with the supplied software, now i am writing my own VB6 program but my problems lay with picaxes ,CR,LF.......I cant get my program to recognize this and VbCr in the Richtxtbox1. I would say I am a intermediate VB6...

Good morning picaxe friends, I am using the picaxe 28 project board and i don't have enough input pins so I am planning on reading several (no more than 4) inputs on the same pin using different resistance levels and the ADC command. Now I know that ambient and load resistor temperature will...
