I only mentioned the npn to say that I am not short of electronic gear in my parts box if need be. The tactile switch on my DDS generator that I have hard wired two wires to measures 5volts normally and zero volts when pressed ( on ) I hope that I have attached circuit diagram to this message...

Hello Forum. I have a dds sine wave generator which I would like to switch on via one of it's tactile push button swithes remotely via my 08M picaxe microprossesor. I have done this with my 08M and an optocoupler and a hacked digital camera on/off switch before, but it won't work for my dds...

Hello. I would like to make a guitar looper, ie. record for up to 30 seconds or more and replay in a loop, using picaxe and probably more memory. It looks like it will not be possible from a Google search, but I thought I would ask to experts here before I abandon the idea. Anyone any thoughts...

Hello. Thanks to Hippy, I got my 08M chip communicating with my AXE033 LCD module. I have connected my DS18B20 Temp Sensor as per "Digital Sensor Temp Kit" -http://www.picaxe.com/docs/axe113.pdf. ie. DS18B20 to Leg 3 of chip and leg 7 of chip to LCD module .When I run the simple four line code...

Hi All. I am trying to make a thermometer using a DS18B20, an 08m chip and an AXE033 LCD module. I have 033 LCD module ( with jumper wire in place ) connected to 08m's power supply ( 4.6volts ) I have tried :- init:pause 500 main: serout 0,N2400,(254,128) serout 0,N2400,("Hello!123")...

Hello Group. I am not too good at digital stuff, but I will try to explain my problem. I am inputing into axe110 datalogger on analogue input 1, a voltage of approximately 0.500 volts, which can increase by + or - 0.001volts each second. I have an axe 033 lcd module attached, but this is reading...

I am having some trouble with timing on my AXE110 Datalogger. Battery Power supply 4.7 volts I am trying to collect data each second for several mins. If I use pause command and set logging period to one second and 60 readings, it takes 90 secs. If I use sleep command and set logging period...

Hi. I would like to verify that an LCD display that I have had a while actually works. I tried to programme a picaxe 18x chip with happy hippy's lcd interfacing programme, but there was a syntax error ( not sure what that means! ) Anyone know how to overcome this problem? David Miles

I would like to use my AXE110 Datalogger to record temperatures. I have tried the DS18B20 digital temp sensor that is supplied with the datalogger, but it seems to give readings in 1 degree C units. I would like a more sensitive response, something like plus or minus point one degree C, or...

HI. I would like to be able control a "voltage controlled oscillator" with an 08m. I have looked through the basic commands and can't seem to see anything that could control or give a variable output voltage. Can anyone give me a clue as to how to go about it?

After you guys helped me to get data into the programming editor terminal, I tried some analogue with a temperature sensor ( ds18s20 ) on input 4. with this programme:- main: ‘ make a label called main readtemp 4,b0 ‘ read channel 4 into variable b0 sertxd ("The value is...

I have tried to put the word "hello" on my computer screen as per page 44 of "micro interfacing circuits" without any luck. I tried:- main: serout 1,N2400,(“Hello”) ‘ Send the word ‘Hello’ serout 1,N2400,(10,13) ‘ Send the ‘new...

I know there have been a lot of posts re 433MHz Tx/Rx, but I can't find one that answers my question of whether they will work indoors bounce around corners/through 4 1/2 inch brick dividing walls for about 50 feet. Anyone know? David Miles.
