Re: Cloud Machine Learning

I made a picaxe LEARN the position of a servo and then play it back... 1/. Measure the current to the servo 2/. Monitor the current while feeding the servo feeble 'feeling' pulse rates of control 3/. SENSE the current versus the signal being fed to the servo as it is gently 'forced' 4/. REMEMBER the...

Re: Where is the Best Place is to Buy a Soil Moisture Sensor That Works Well With Picaxe?

You will need to do some maths to 'calibrate' the raw reading from the code into meaningful 0 ~ 100 % so let me know if you need help with the maths in picaxe as this can be a bit tricky... Note that 0 will = max 'dry' = 0 % moisture some maximum raw number will need some slightly tricky maths to ca...

Re: Where is the Best Place is to Buy a Soil Moisture Sensor That Works Well With Picaxe?

The next thing you need to do is CALIBRATE this system. When soil is completely DRY you will get zero or 'NO' reading at all When soil is completely WET you will get a very HIGH reading So if you do da science you could calibrate this sytem to make it very accurate like this.... 1/. Take 100g of DRY...

Why buy one when the best one you can make yourself :)

All you need to make this work is 2x Nails and a 10k resistor.
Use
do
readadc 1, b1
debug
wait 1
loop

Re: arduino bluetooth keyboard

Two versions of this

Make SURE if you want blue teeth you get the right model
They make very nice build quality
I have a BT mini standard kbd for Pi and it is brilliant... works direct into Pi0w's via BT with NO dongle needed (but supplied) etc

Re: I want to make something with Picaxe that senses when a laser touches it and lets off a loud beep.

use a solar panel in a white box set behind an opaque screen like a sheet of A4 Paper or plastic photocopy.
Monitor the mV coming from the panel with readadc / readadc10 command.

Re: I want to make something with picaxe that listens to any noise then transmits it wirelessly to another picaxe unit t

Yup, you will need something more sophistocated than a picaxe. The most you can do typically is just 'Detect' noise. Even if yoou cranked up the clog rate of the picaxe you would not be able to get much "fidelity" as you need to sample at 2x the highest audo freq to get even clunky telephone type so...
