I would like to use a potentiometer, but then converting a vertical mechanical rise and fall to a rotating clockwise and anticlockwise shaft is even more challenging than a magnet in a float..Ultrasonics isnt easy either.. I am also trying to make a water level indicator in a mobile tank...

thankyou buzby, option 3 is what I intend to do, from what I have read about picaxe adc inputs , the picaxes ignore the input voltage between 3.7 volts and 5 volts, and thus the pull up resistor from the 5 volt rail to the 3.7 volt point , will be constant, probably 1kohm for this...

Thankyou rq3, can I have a 50mv resolution without going to a 32 mhz resonating rock, like can I just go with the internal resonator and still get as low as 50mv distinguisable steps, like I want to have a clockspring type arrangement that uses switches to ground out a series string of 100 ohms...

Is it possible to program any of the picaxe micros :adc: down to as little as 50 millivolt levels ie the picaxe gives a different output for every step level change of 50mv either up or down..?

Just want to know which , if any, of the picaxe micros can do parallel tasking, ie more than 1 start block in the flowchart programming chart technique..

Wanting to program 20m2 device in flowchart, pre selecting ins and outs, but input c6 is greyed out in preselect programming screen,, but datasheet diagram indicates c6 is available as input, is c6 input available as a useable input or not? Regards Peter

is it possible to program a picaxe for voice recognition commands

Thankyou, does anyone know who sells the axe213 rfa001 kit in australia. cant find a picaxe distributor that does as yet..

is it possible to use the axe213 / rfa001 picaxe wireless link to output out of the receiver a bcd output when the transmitter sends the same bcd input, eg say I wanted to send a bcd value of 6 which is :abcd/1248 = 0110 from the transmitter to the receiver, can the receiver output 0110 ...

I have a project that needs to accurately read down to as low as 50mV in 50mV increments up to about 2 volts, for about 30 increments of 50mV.. How accurate can I go with the picaxe devices of 08m, 14m, 20m 28x2 and 40x2 and preferably not use an external resonator..

out of curiosity, are you in the uk atm?

From what I have been able to find out, the Ji2c pin goes to vcc ie 5 volts, the ji2C pin goes to vcc when connected to an arduino device, ill give this vcc connection a go and see what happens, and let you know..There is no indication as to where its made on the board itself but the blister...

Thats the problem with this quad display, the supplier in australia isnt able to provide any datasheet info on the product at all, the only info I have is the vk16k33 device that is actually on the quad led display itself, apart from the scl and sda labelled pins, it has this Ji2C pin, just not...

The quad display has another pin labelled as Ji2C , where should this be connected to for a 20m2 picaxe?
