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. WebJul 17, 2015 · Then use this voltage divider to create 3.3V supply. simulate this circuit – Schematic created using CircuitLab. Use the circuit below , and as datasheet suggests that the forward voltage is about 1.2V (led voltage) and maximum current should be 20mA so the resistor R1 can be calculated as. WebAug 22, 2024 · Even though you didn't mention the battery size, as soon as you mention button, you can think of a 3V cell with high ESR value. CR2032 Maximum discharge current: 3 mA.
