WebIdea of using zener diode is good with small series resistor. How do you reduce 9V to 3v? To reduce a 9V battery to 3.3 volts, use a zener diode, such as a 1N746 or a 1N4728A. Choose the appropriate one based on how much power it can dissipate. A 1N4728A has a 3.3-volt and a 1 W power rating. … 12v to 5v converter using a voltage divider:

WebThe circuit above shows a voltage divider circuit involving a 2kΩ and a 1kΩ resistor. If the voltage from the microcontroller is 5V, then the leveled-down voltage to the sensor is calculated as: V out = 5 ∗ 2kΩ 2kΩ +1kΩ = 3.33V V o u t = 5 ∗ 2 k Ω 2 k Ω + 1 k Ω = 3.33 V. This voltage level is now safe for the sensor to handle.

You cannot step down voltage with a resistive voltage divider. I mean, you can, but then you must not draw current from it – the whole idea of why the ratio between the voltage across the lower and the upper resistor is known is that the same current flows through both.. So, your approach can’t work. You need a voltage regulator – 3V is pretty …

Step down from 6V to 3V without sacrificing current

Very new to electronics so I will try to be clear. I have a 6V 1.8mA power supply and 3 different DC motors – one is 6V and the other 2 are 3V. All of my motors re

9V is fine. 2V drop over the L293D (that’s simply lost as heat) leaves about 7V for the motors. Likely not a problem. Especially as those AA batteries will quickly drop to 1.2-1.3V output. If still too much just keep your PWM levels down a bit. An analogWrite() value of 220 will reduce the average current of a 7V supply to that of a 6V supply.
I am currently doing a project which uses 2 dc motors(6v) controlled by a motor driver(l293d),a servo, a rain sensor and a ultrasonic sensor.I am planning two use 6xAA batteries to power the whole thing(including an arduino).My problem is that is i do not know how to change the 9v to 6v which is needed by the motors.
A DCDC buck converter can be used for that. Which one depends on the current need of the motors.
Other way would be to change to 4xAA and use a
