I have 2 6v dc motors for a tank tred kind of project. so they will need to be driven independently. Though that's not the part I'm having trouble with.
I hooked up 4 transistors to a motors power leads and had an output from a microcontroller to two base pins of 2 different transistors. So current could flow through one direction then another two for the same set up to drive it in the opposite direction, with another wire from the micro-controller to turn it on. For every base connection I had a 330 ohm resistor.
This worked. Though what went from a strong push that could climb everything can not turn the wheels when placed on the ground.
The transistors I use are 2N3904.
Is it just the case that these transistors will drain that much of the current or is something wrong with my circuit. Any help is much appreciated
I now know this circuit is called a H bridge. The searching hasn't helped me. Though I'm still not sure what I am to do. Do I need different transistors?
