I'd like to use porB to control 4 motors with external dirvers. But I think I have not direct conecctios to PICAXE B pins (Axe020).
It is necesary to use a L923D driver?
This program works fine with my HC-06s

I usually control bots with a remote control and with Bluetooth.
The "read infrared" timeout option is very useful because you can read a remote and do other things.
But timeout is not available with "serial in" block.
My students need to write a block with the Basic code (that don't...
Blockly. Minor suggestion
CHI035 Motors fordwar Basic code is low B.5,B.7 : high B.4,B.6
Motor C Fordwards Basic code is high B.5 : low B.4
Should it be low B.5 : high B.4? (same to Motor D)
Hi Jurjen
I'm using PICAXE for 8 years at School
In my BLOG you can see lots of robotics practices and proyects
Last two years I'm using the Guide to introduce each element (mainly sensors and actuators) before abording proyects
Hi
This is a small contribution to PICAXE teaching.
It's a Reference Guide (still in development) I use with my 13-15 y.o. students.
There are lot of sensors and actuators with circuits, programs, practices and about one hundred videos.
Sorry, it's in Spanish (by the moment)!
I hope you like it!
Hi
I'd like to control the speed of a 5V DC motor using a CHI035 board (PICAXE 18M2+)
There are two pins, B.3 and B.6, to work with PWM.
1) In the wizard, I can set the Frequency (61 - 500000Hz).
But, which is the best frequency to work with a DC motor? It doesn' matter?
2) With PWM, is it...
Hi
In a list, how do I get the center value in a fast way?
I've got a sensor, but sometimes it sends incorrect values.
What I am thinking is to try 5 measures and take the central value. It's enough for me.
For example, if I get : 78, 84, 83, 0, 85, the central value is 83 (0-78-83-84-85)
Let...
If I write this program, it works fine for me.
I get one number per line in Terminal Serie.
But if I save it, close it and re-open it, then the " - \r" message changes.
And if I check it I get an error.
Could you check it, please?
