There are three ways to interconnect resistors: series, parallel and in combination of series/parallel. When resistors are joined in series, the current passing via one resistor also passes through the next. When resistors are joined in parallel, they are wired across each other, resulting in the same voltage across each resistor. When resistors are connected […]

Blinking LED Circuit using LDR and Resistors
This is perhaps the most simplest looking LED flasher that does not depend on any semiconductor. This LED blinker circuit utilizes ordinary passive components like a few resistors, a capacitor and an LDR. Meaning, this LED flasher does not depend on transistors or ICs to create the blinking effect. Circuit Description The LED-LDR combination is […]
Understanding Pull-Up and Pull-Down Resistors with Diagrams and Formulas
In this post I am going to explain pull-Up resistor and pull-down resistor, why they are commonly used in electronic circuits, what happens to electronic circuits without Pull-Up or Pull-down resistor, and How to calculate Pull-Up and Pull-down resistor values and finally we will see about open collector configuration. How Logic Inputs and Outputs Work […]
