In addition, when the requirements of this node when the high level of impedance between your node and the ground is generally very large, such as the 100K impedance, resistance and you pull a 10K if the voltage point for *100=4.5V (5/100+10) that can be on the high level. When ...
Voltage, Current, Resistance Digital Logic Input/Output What is a Pull-up Resistor Let's say you have an MCU with one pin configured as an input. If there is nothing connected to the pin and your program reads the state of the pin, will it be high (pulled to VCC) or low (pulled ...
Assume we want to limit the current to 1mA when the button is pressed, where Vcc = 5V. What resistor value should we use? It is easy to show how to calculate the pull-up resistor usingOhm’s Law: R1 = Vcc/I = 5V/1mA = 5KΩ Another thing is that the larger the pull-up resi...

Is it a high or a low? The MCU doesn’t know and you might read either a high or a low. A resistance of 10k to 100kΩ for R1 should avoid most problems. Since pull-up resistors are so commonly needed, many MCUs, like the ATmega328 microcontroller on the Arduino platform, have int...
connected together, the resistance becomes C pull resistance, also that is to say, if the high level of the port is normal, C through a resistor and connected together, the resistor called pull-down resistor, the port is usually low, effect: ...
pull-up resistance value is too high, combined with a large leakage current of the input pin, the input voltage can become insufficient when the switch is open. This condition is called having a weak pull-up. The actual value of the pull-up’s resistance depends on the impedance of the ...
1.1. Resistance Resistanceis caused due to the electrons in a conductor colliding with the ionic lattice of the conductor which results in the conversion of electrical energy in heat. 1.2. Impedance Impedanceis the measure of the nature of opposition of the AC electricity which is created due to...
