Here are 3 simple electronic circuits by using basic electronic components.
1. Simple Preamp Circuit
"Sometimes we use a Preamp Circuit in circuits for pre-amplification of weak signal when the audio source sound level is too low. Pre-amlification of low level signals is necessary before feeding them into a power source, for clear and noiseless sound." So here we will build this Simple Preamplifier Circuit using NPN transistor BC547.
2. Bike Turning Signal
This fancy Car/Bike Turning Indicator Circuit uses a 555 Timer IC along with four yellow color LEDs glowing one by one in a particular pattern and we can control the speed or frequency of this LED indicator by simply turning a Potentiometer. This works in the similar pattern in which bike or car's turning signal works. Here you can find all the required details to build this circuit.
3. PWM Generator Circuit
PWM is very important concept in electronics engineering. To understand this concept and make a simple circuit with this, we used a 555 timer IC along with a potentiometer, a capacitor and few registers which generates PWM signal. You can learn about PWM concept with building this basic circuit.
