1. first of all, do i need a seperate 7VDV battery pack for each motor? i think if i try to split the current from 1 pack to 2 motors, the current draw to each motor will be halved which would decrease my torque output, which is not good. am i right?
2. if i use a seperate 7v battery for each motor, how do i make a power regulator circuit for each one? i have no idea how to come up with the circuitry for it so help would be appreciated?
3. i also need to power up my microelectronics, which means that i need a seperate battery pack for them?? can i just use the battery output from one of the motors for powering the microelectronics?...i dont think my microcontroller draws more than 450 mA so the torque output of that one motor should not be affected too much......
[...] can someone give me a list of all kinds of circuits i need for my robot (e.g. h-bridges, power regulator etc.).....thnx!!!!!
anyways, i have decided that i am using 2 -7.2VDV motors and a microprocessor that uses 5V. I am going to use a single 9V battery for each motor and and and a 9V battery for the microprocessor. So I am going to place 3 - 9V batteries in parallel and connect them to a power regulating circuit and connect the circuit to my 2 H-bridges (each of which connects to a motor), AND the microprocessor. How would I go about creating such a circuit (i.e. what is the schematic of the circuit and what components does it have)?
[...] every page i go on, some dude uses random capatitance values
[...] and etc for his regulator circuit and they dont say anything about why or how they arrive at the circuit.
[...] and since i am a little tight on project time, i thought it might be helpful hitting the forums and having someone who has years of experience, to explain to me some basics in layman's terms.
i beleive this circuit here: http://That.Homepage.dk/PDF/24V+5V_PSU.pdf was refered by you regarding a similar topic. however, AGAIN i do understand where all the numbers and capacitance/resistance values and stuff like that come from.
2. i need to understand the circuit: i) for my own curosity, but if your dont have the time to explain it, you dont have to.
ii) because im not using the exact same voltage source (im using 7.2 V instead of 24V) and i want to find out if i have to change the resistance/capacitance values in the circuit.
