Here I have explained four best electronic thermometer circuits which can be universally used for measuring body temperatures or atmospheric room temperatures ranging from zero degrees to 50 degrees Celsius. In the previous post I explained some of the features of the outstanding temperature sensor chip LM35, which gives outputs in varying voltages that’s directly […]

Here, I will elucidate the datasheet of the IC LM3915, its pinout functions, its main electrical specifications, and also a few useful application circuits. General Description The […]
Triacs – Working and Application Circuits
A triac can be compared to a latching relay. It will instantly switch ON and close as soon as it’s triggered, and will remain closed as long as the supply voltage remains above zero volts or the supply polarity is not changed. If the supply is an AC (alternating current), the triac will open during […]
Simple Circuits using IC 7400 NAND Gates
In this article I will elucidate many assorted circuit ideas built using NAND gates from ICs such as IC 7400, IC 7413, IC 4011, and IC 4093 etc. IC 7400, IC 7413 Specifications The I.C.s 7400 and the 7413 are 14 -pin DIL ICs, or “14 pin Dual In Line Integrated Circuits”, where pin 14 […]
Temperature Regulator Circuits using IC LM335
There are many cases where it is desirable to actively regulate the operating temperature of an electronic assembly. Sometimes, it is imperative to dissipate the heat generated by the components (this is the case for the majority of microprocessors in our modern PCs). On the contrary, it is necessary to artificially increase the operating temperature […]
Diac – Working and Application Circuits
The diac is a two-terminal device having a combination of parallel-inverse semiconductor layers, which allows the device to be triggered through both directions regardless of the supply polarity. Diac Characteristics The characteristics of a typical diac can be seen in the following Figure, which distinctly reveals the presence of a breakover voltage in across both […]
