void setup () { pinMode (2, OUTPUT);} void loop() { digitalWrite(2,HIGH); delayMicroseconds(50); digitalWrite (2,LOW); delayMicroseconds (15); }
It was in some other literature, but it is also in the drop down box for pricing.Ah I didn't see post 5! How do you know it would be 300 dollars?
First you have to find out how much current the DC to DC converter needs, then design a switching converter for that much current.How exactly does that circuit with the 7812's work? I thought the 7812 stepped the voltage down linearly and there was a lot of inefficiency with it.
