Pregunta 1:
Compre una protoboard vino para alimentarla con una YWRobot. El tema es que nose como alimentarla sin quemarla mis conocimientos en electronica son limitados.
The AMS1117 is a voltage regulator manufactured by Advanced Monolithic Systems. There are two regulators where one regulator establishes a 3.3 V rail, whilst another establishes the 5 V rail. These are a good make of components found in a SOT-223 package. Their documentation states that this series can provide a maximum output current of 1 A, and the absolute maximum input voltage rating is 15 V.
The documentation indicates that these regulators have built-in protection against short-circuit through power limiting circuitry. There is also thermal overload protection circuitry, which will shut-down the regulator should its junction temperature reach 165 °C.
These regulators also have internal diode protection and can handle transient surge currents from 50 A to 100 A.
This is a high efficiency low dropout regulator, which can operate down to 1 V. It has a 1 V input-to-output differential and therefore useful for battery powered applications. Line regulation is 1.2 % and maximum load regulation 0.4 %.
The AMS1117 series is an excellent choice for creating adjustable power supplies as well. The package provides a 1.25 V reference voltage from the adjust pin, and with a pair of resistors in a voltage divider network the regulated output can be adjusted. The documentation is also very clear and comprehensive in its use.
Estos son los transformadores disponibles en mi casa y pilas para pruebas.
Pregunta 2: Como aconsejan alimentar la protoshield motorboard y 2 motores?
Esto es para regular unos motores (que todavia nose como voy a hacerlos andar bien).
Los motores son los de vibracion de los joystick de playstation 2 (los cuales nose si funcionan a 3v o 5v), al tener varios joystick rotos tengo varios para probar pero nose si les daran la fuerza para mover un vehiculo chiquito.
Iria alimentados a una protoshield (la protoshield tiene 2 l293d, o sea que puede manejar 4 motores chiquitos, de echo si compran l293d pueden usarlos para manejar el motor, no necesitan la protoshield). La cual todavia la estoy investigando.
La protoshield al ir montada sobre el arduino uno, ocupa unos pines (segun cuales y cuantos motores usen).
What pins are not used on the motor shield?
All 6 analog input pins are available. They can also be used as digital pins (pins #14 thru 19)
Digital pin 2, and 13 are not used.
The following pins are in use only if the DC/Stepper noted is in use:
Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)
Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)
Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)
Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)
The following pins are in use if any DC/steppers are used
Digital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595 serial-to-parallel latch
The following pins are used only if that particular servo is in use:
Digitals pin 9: Servo #1 control
Digital pin 10: Servo #2 control
Con respecto a la alimentacion se puede jumpear (aunque nose si hay que agregarle los pines para el jumpeo) indicando que se alimenta de una fuente externa (ver placa) o directamente desde el arduino (poco aconsejable).
