LED resistor calculator
This LED resistor calculator is a useful tool to calculate the resistance value of a current limiting resistor. It can also find the color code equivalent to the calculated resistance. Normally an LED draws 20mA current at 2-3.5 volts. If the input voltage across an LED is less than its highest voltage rating then it …
Comparison of Arduino boards
Nowadays there are many Arduino boards are available in the market. As of now, we have only discussed the Arduino UNO only. In this article, I have differentiated between some popular Arduino boards. Here you will find a detailed comparison between some Arduino boards. Now, the reason behind they launched different types of boards is …
OpAmp gain calculator
Inverting OpAmp configuration Non-Inverting OpAmp configuration Inverting op-amp As the name suggests this configuration of the op-amp will invert the signal given on the input terminal. For that, the signal is given to the inverting terminal. Now let’s understand the logic behind the inversion of the input signal. If you know the op-amp wants to …
