Voltage Follower Schematic
... If the power supply is fluctuating, it can’t compare accurately and you will end up with noisy data. We have a Power Injector and Powered Expander that can be used to add 500mA of power to an interface, although you can make one on your own using a wall wart and a decent voltage regulator: something ...

PWM Circuit Based on the 555 Timer
... Introduction In applications LED Brightness Control we may want to vary voltage given to it. Most often we use a variable resistor for that. The main problem with this control is the power dissipation across the variable resistor. This problem can be avoided by using Pulse Width Modulation (PWM). ...

Power supply description
... Usually, DC voltages are required to operate various electronic equipment and these voltages are 5V, 9V or 12V. But these voltages cannot be obtained directly. Thus the a.c input available at the mains supply i.e., 230V is to be brought down to the required voltage level. This is done by a transform ...
