To determine the appropriate resistor size for reducing voltage from 12V to 5V, you would need to consider the desired current flowing through the circuit and the specific voltage drop requirements. Using Ohm''s Law (R = V/I), you can calculate the required resistance value based on the current and voltage drop across the resistor.

Or, V1 = V2*R1/ (R1+R2); V1 =5, V2 = 12; pick an R1, solve for R2. Either way, if you use 10k for the lower resistor, you need 14k for the upper. (Put the lower resistance to ground, higher resistance to 12V). Now, 14k is not a standard value, but the trick is, any ratio resulting in 1:1.4 will work.

step down 10v to 5v with a resistor? | Electronics Forums
Jun 20, 2010. 485. Oct 29, 2010. #6. (*steve*) said: The short answer is: No. The long answer is: Maybe, but it probably won''t work. What Steve said. A slightly longer answer is that you might actually get a resistor to work but at the very least you''re risking a drastic reduction in the lifespan of your motor.

This circuit converts 12 V from a car battery to 5 V and provides up to 500 mA current output, to power a USB device. If a 5.1 V Zener diode is used, and it requires 5 mA to maintain the 5.1 V Zener voltage, then calculate the value of the voltage drop resistor R. Use the E24 series to provide a suitable value of the resistor.
crimony May 6, 2008, 9:24pm 13. Check your transistor circuit operation first. Ground the input and observe 5V on the output, then put +12V on the input and you should see 0V on the output (as this circuit is inverting). system May 6, 2008, 10:34pm 14.
How can I use a 12 V input on a digital Arduino pin?
A simple resistor divider will bring the 12 V down to the 5 V an Arduino can digest. The output voltage can be calculated as. VOUT = R2 R1 + R2VIN V O U T = R 2 R 1 + R 2 V I N. Resistor values in the range of 10 kΩ are a good choice. If your R2 is 10 kΩ then R1 should be 14 kΩ. Now 14 kΩ is not a standard value, but 15 kΩ is.
3.3kΩ resistors (orange, orange, red) are the R2''s, 1.8kΩ resistors are the R1''s. An example of voltage dividers in a breadboard, level shifting 5V signals to 3.24V. (Click to see a larger view). Keep in mind, this solution only works in one direction. A voltage divider
PLace two resistors in series with the 2nd resistor value (5/7) of the first resistor value. Place the resistors between 12v and ground and then you will get 5v at the point between them. This is a very crude way of doing it. It is unregulated so the voltage out will be dependent of voltage in. You will also have to be concerned with power ...

A voltage divider circuit is a very common circuit that takes a higher voltage and converts it to a lower one by using a pair of resistors. The formula for calculating the output voltage is based on Ohms Law and is shown below. where: V S is the source voltage, measured in volts (V), R 1 is the resistance of the 1st resistor, measured in Ohms (Ω).

MC34063 can be configured in three mode, Buck, Boost, and Inverting. We will use the Buck configuration to convert the 12V DC source to 5V DC with 1A output current capability. We have previously built simple Buck Converter circuit using MOSFET; you can also check many more useful power electronics circuits here.
So if we have a 12v battery powering a 3.5V 25mA LED our formula becomes: (12 - 3.5) / (25 / 1000) = 340ohms. But wait! (you might say) When I use one of the other calculators I get 390 ohms! And indeed you do. That''s because its hard to buy a 340 ohm
Convert 12V to 5V by using 7805 or using Resistor?
Smaller one is always welcome. Vin pin require 7-12V, as Arduino Nano have his own voltage regulator to 5V (LM2940). If you want to power it by your regulator, connect output pin of 7805 (5V) to 5V pin on Nano. The 7805 need between 2 to 2.5V to work properly up to 1A constant current, thus ideal input voltage is around 7.5V.
When there is 12V to 35V DC supply available and you need 5V from it then you can blindfoldly use Positive Voltage Regulator 7805 (maximum current limit 1.5A). This IC have only three pins, First one is for input and 2 is for Gnd and 3 for output. Connect the IC 7805 with appropriate capacitors for input and output stabilization.
