So I went balls out on a project for work utilizing the touch feature of the 20m2, basically three buttons (copper wire strands rolled into a circle) behind some plexi glass, I got some base readings and some button pressed readings and wrote some code. Little did i know that all my readings...

On a voltage regulator like lm2576t what is the min input current and/or voltage needed to achieve 3amps?

I bought five of those eBay max7219 8x8 dot matrix kits, it didn't have a datasheet with it but google tells me that it may require up to 2 amps each? Is anyone familiar with these? I should be able to set them up in cascade by connecting one with dout pin to the next with din pin?

Has anyone ordered anything from the picaxe store who's living in the US, I'm in Houston TX and want a PCB scope(OSC001) but just wondering how long it would take for me to get.

In this diagram should the suppression diode go to the 12v side or the picaxe 5v?

I have a program that counts hours and minutes when slot 1 runs, when the program shuts down it stores hours info in i2c eeprom like so setfreq em32 #slot 1 ;#terminal 38400 #no_data #no_table keeptime: do if pinC.5 = 1 then gosub xxsecs ; 1hz signal if pinC.7 = 1 then...

I'm trying to figure out how the comparator function of a 28x2 works. I want to hook up a two wire fuel sender(the type you see in older cars) to it. One wire goes to ground with the other wire will be in a voltage divider type setup reading .5v(full) to 3.0v(empty) or so. My question is will...

I'm working on a project where i need a bar graph to display on a 20x4(one line) display to show readadc data from 0 to 100%(0-255). Ive searched and searched but haven't found a way to do this the closest I've came is this and it has some issues .. has anyone done this before, I don't want to...

I have a 20m2 and writing a program the memory became full at about line 638 and I have exceeded 2048 bytes.. and i have a about 300 or so bytes to go to complete the project. I was looking to buy a 20x2 or 28x2 but in my research ran into this which is kinda confusing. under the m2 parts...

I made a adjustment to marks code to auto adjust for daylight savings time in the US. The rule is as follows: begins(+1 hour) at 2:00 a.m. on the second Sunday of March and ends(-1 hour) at 2:00 a.m. on the first Sunday of November this is the code tell me what you think the lines in red is...

I have a lcd running in 4bit mode successfully on a 20m2 with int setup like so symbol E = c.7 symbol RS = c.5 int: let dirsC = %10011111 I tried this with RS on b.6 but failed int: let dirsC = %10001111 let dirsb = %00000010 Is it possible to change RS to the B port side...

what can it input?

Is it possible to code a momentary button's long press at a input? for instance.. pressing it once turns on a light, pressing it again will turn it off, holding it down for a set amount of time will make it flash. also on a unrelated topic what do ya'll think about this Mosfet? I should be...

So oi bought a 2x16 LCD and connected it parallel, I want to use it to display variables like i2c info but searching on how to do this yields little to no info, so I'm planning on sacrificing a chip and turning it into a serial LCD or i2c.. Please advice which should be better.

I have a rtc module I bought on eBay, I set the time and is working well, I see it has a slot for a temp sensor which I have, will putting this in automatically give me temp compensation or do I need to use it with code. Also on my 2x16 LCD how do I get it to display numbers or letters on both...

I just got a 16x2 LCD display today, its doing something strange anyone know why? the end is fading in and out http://youtu.be/f148eUvGtFk i got the code from http://technologytutor.co.nz/picaxe-circuits/01-how-to-connect-a-lcd-to-a-picaxe I'm using a 20m2 in 4 bit mode

I'm working on a generator project, if the generator shuts down will out put a diagnostic code similar to the type old cars used to put out(see attached pic). Its 12v high and low, I'm going to use resisters to pull this down to about 4v so my newly ordered picaxe 20m2 or 08m2 can read this and...

Ive been trying to hook up a rtc clock to my 08M2. after writing a code i found by marks http://www.picaxeforum.co.uk/showthread.php?18505-DS1307-Code-Examples SYMBOL character1 = B2 SYMBOL character2 = B3 SYMBOL character3 = B4 SYMBOL character4 = B5 SYMBOL character5...

I got this RTC from ebay. It has six pads numbered 1-3(shown in attached pic), is this some address selection for communication? i cant find any info on the web about it. This should have the 4.7k pull up resisters already on the board correct?

i have a push button i want to use as a input on my 08m2, Its normally closed meaning it disrupts current when the button is pressed, how can i set this up?:confused:
