How to use multiple solar panels?
Calculating watts Power[watt]=Voltage[volt] * Current[Ampere] if the panel is rated as 5v 200 mA then Power=1 watt Wiring multiple solar panels Parallel wiring This is required if your application need more power than rated. By connecting the positive terminal of…
How radio works?
How does radio works? Audio signals are transmitted by imposing lower audio frequencies on the high frequency carrier wave. In other words the audio signals are added to the carrier frequency. Its amplitude is modulated. At the receiving end, a…
Basic Electronics – Resistance and Capacitor codes
Resistance colour codes Below is the table containing resistance colour codes. Each color band represents a number and the order of the color band will represent a number value. The first 2 color bands indicate a number. The 3rd color…
Basic Electronics – Resistor Combinations
RESISTOR COMBINATIONS When we do not get specific resistor values we have to either use variable resistors such as potentiometers or presets to obtain such precise values. Pots are too expensive to use forevery case. Another scheme is to combine…
LED Basics
Today LED has become an integral part of consumer electronics. LED TV, LED Display, LED Lights and so on. These are becoming very popular because of there low power consumption. What is LED? LED stands for Light emitting diode. A…

Passive Components RESISTORS To oppose the flow of electrons ( current). The symbols are shown below. Resistance is measured in units called “Ohm”. 1000 ohms is shown as 1k ohm (103 ohm) and 1000 k ohm is shown as M.ohms…
Basic Electronics – 1
Introduction Electronic component can be divided into 2 types: Active and Passive components Resistors and Capacitors etc. are known as passive components because they can only attenuate the electrical voltage and signals and cannot amplify. Devices like transistors and operational amplifier(op…
