[Systems Engineering Teachers' Mailing List] PICAXE Help

[Peter A Ward]

Dear Roger,
Try using a relay. The Picaxe may not be able to supply the windscreen  
wiper motor with enough current or its getting interference back from  
the motor.
Here is some examples of relays used to run 12 volt car motors from an  
08M picaxe from a couple of years ago.





relay with picaxe 08M



This was an egg incubator  eventually controlled by a picaxe via relay.

Hope this helps
