Re: H Bridge Starter Idea

And this one has "Current Sense" by just adding a 1 ohm resistor: A few handy rules of thumbs: - RPM is proportional to Voltage - PWM to a motor just looks like a perfect changing DC voltage and will change the RPM nicely - Current is proportional to then Torque / Load on a motor. This can be used t...

Re: H Bridge Starter Idea

This idea shows how it is possible to control TWO motor F/R from just 2 Pins.
If you make the OP pin an input the motor also STOPS.
Cute starter idea for a cute robot perhaps ?

Re: Lynfield collage, picaxe code (elevator), help

Add tothe above that the debug statement CAN mess with the PWMOut command as can the Nap / Sleep commands.... Sertxd is Much more user friendly and FUN !

Add in the LCD txt messages as you go etc or inparallel with the sertxd monitor test points in the code

Re: Lynfield collage, picaxe code (elevator), help

1/. It depends a lot on where the LDR's are and how things are set up I use a very simple PWMOut that uses just bx variables to make things simpler 2/. I use 64 as the chopping rate / time base makes the amount of PWM easy (0 to 255) = 0% to 100% for b0 = 0 to 255 step 5 pwmout 2, 64, b0 sertxd (#b0...
