Control of a high frequency ignition system based in corona discharge with Arduino 3 A.ARDUINO CODE This section contains the code that was used in the project and the Arduino library <PWM.h> necessary

if the data sheet is wrong? lt doesn't happen often but take the 8C639 transistor. This device comes packaged in a plastic TO-92 outline and all the data sheets agree; with the transistor's flat face on the bench and its leads pointing towards you they read, from left to right; base, collector and emitter.
