In an intended application of the composite integrated circuit to a startup circuit of a switching-mode power supply, the multipurpose resistor serves as startup resistor for limiting the flow of rush current during the startup period of the switching-mode power supply.Keiichi Sekiguchi...
Too many button clicksButtons and tactile switches are frequently used in many projects involving micro controllers; one of the most frequent issue is related to unwanted multiple transitions when the button is pressed once.Tactile switches as well as pu
I don't know the physical configuration of the electrodes in your example, but the only situation where I could see much benefit to U1 would be if there were some source of current leakage into or out of the circuit, and most such leakage would be concentrated on the electrode tied to t...
A rheostat is a variable resistor made of resistance wire and often three terminals. The rheostat was invented in the 1840s by English scientist Sir Charles Wheatstone.Answer and Explanation: The purpose of a rheostat is to vary the resistance in a wire, such as when you want to control ...
(Note that if your device is powered by a 5 Volt supply, you should jumper J1 to the 5 volt supply.) LED Driver This circuit consists of: ID DefaultValue Install? Notes Qa yes transistor, see below for advice on selecting an appropriate transistor and base resistor. Ra yes base ...
Pull-up/down resistor: It sets the status of GPIO pin in IDLE or in condition of invisible input signal. The Pull-up resistor will connect the GPIO pin to the positive to set it as the default high-level status. While the Pull-down resistor will connect the GPIO pin to the GND to ...

There is no amplification given by this circuit. As a consequence, the voltage gain equates to 1. It is also known as the amplifier for unification gain, buffer & isolation. The input impedance of this circuit is high, so it is used in various circuits. The input signal is used by ...
A bushold circuit is added to the data input of an IC. Consisting of two inverters in a feedback loop, the bushold circuit holds the state at an input pin at its last known state whenever it is left open (i.e., floating). Fig. 1 Bushold circuit for general-purpose Logic IC...
Note that Rb is not normally installed in the 5V configuration. However, in some cases where the voltage swings rapidly, installing a 1M Ohm resistor in the Rb location and leaving Ca out is preferable (this creates the equivalent of the MegaSquirt®EGO input circuit). If the supply voltage...
