Hello all, sorry if this is a bit off topic. I am tiring to make an IR to RS232 converter. Basically I want to send commands from a universal remote control (Logitech harmony 880) and then send commands to a light controller (Clipsal C-BUS). My devise will not send IR commands. The universal...

Hi All, just a quick question, can i connect a output pin on one pic to drive the MCLR pin on another, using a resistor to join the two. Basicly i want to reset a pic using another. Thanks, Mark

Hi All, i know i have seen this asked before (i think on this forum) but i cant find it. Basicly, i need to drive 8 relays off a picaxe using a darlington. This is not a problem, but i go need 150 mA of current to each relay, total of 1440 mA, so i will need to use 2 parallel voltage regulators...

Hi all, Just got one quick question.What is the best way to protect analog inputs from over voltage?? Thanks, Mark

Hi all, i am in the final stages of getting my aquarium controller working, i just have one more problem. I need a dual power supply for my op amps. i am using a 7805 and 7905 to give me +/- 5v, but currenty i have a 12v center taped transformer, so it has a 0 volt pin. Is there any way i can...

Hi all, i am tring to read a voltage coming out of a cheap digital PH meter. The meter have op amps to boost the voltage coming out of the probe to 0-3 volts. I have tried to just connect this up to a analog pin on a picaxe, and reaf the value, but the value is just garbage. Somtimes it is a 0...

Hello all, i am building a gokart computer and would like to know the RPM of my motor. I have seen in the shops that they do not use hall efect sensors, but only have a clip on the sparkplug lead. I think this has somthing to do with induction but i dont know too much :). can sombody explane to...

hi all, sorry to ask such a dumb question, but i dont know to much about this. I have got myself a 4x20 LCD. can i use the LCD firmware to drive it?? Also, the LCD has a back light, it needs +4v to work, if i give it 4v, it is ok, but i need to drive it from the picaxe. Do i need to use a...

Hi all. I have a intresting project on my hands. I want to read the ALDL data coming from my car into a picaxe. I dont want to know how to do this ( i want that fun to myself) but if i can do it. The data is quite slow (160 baud). Do you think this is going to work???

Hi all, is there any way to waterproof a DS18B20. I was thinking about dipping it into resin(very thin layer) Will this work?? Thanks, Mark

Hi all again. After reading all posts in the forum regarding this, i still can not get a 12 bit reading from my DS18B20.The following is my code. SYMBOL DS18B20_PIN = 6 ; Input pin 6 SYMBOL temperature = w2 SYMBOL temperatureLsb = b0 SYMBOL temperatureMsb = b1 SYMBOL scratchpad = w3 main...

Hi all, i have a quick question. Is there any way to get the DS1307 to "push" the time out. I need to display the time on a lcd in my project, but not to sure how to do it. Also, this is my code to bit mask the time and display it (it is been displayed on my PC for now). Is this the...

Hi all, i was wondering if it is possable to change with pins get used when i connect a LCD to my PICAXE18x. I am not using the serial firmware, and i want to be able to use i2c, but the lcd is connected to pin7, which is the i2c connector.
