Help with H-Bridge
Hello, I need some help to reduce the chances of burning my precious Arduino/apartment.
I managed to build and test this H-bridge made out of transistors on a breadboard, and to my surprise everything worked perfect, I was able to use PWM to adjust speed and drive the motor back and forth.
My question is, will I create a short if the two inputs receive signal at the same time? right now they alternate between HIGH and LOW or 0 and higher numbers with the analogWrite or digitalWrite functions. I ask because I might want to vary speeds according to a sensor or similar and at some point current could flow through both inputs?
Also I want to build a shield with two of these H-bridges to control two motors, what other considerations should I have?
note: this diagram shows the transistors from below.
first two are PNP, the other four are NPN
