Transistor Based Vehicle Indicator
While driving car, Before taking a turn it is a good practise to use the indicator, which will not only alert the other vehicle driver nearby you but reduces the chances of accident as well. But if your vehicle indicator is not working well then you can use this simple circuit. In night many accident took place because of less traffic, high speed and casual driving. We forget to use indicator and speeding vehicle behind you or from opposite side does not get time to slow or stop their vehicle. Therefore the use of indicator is always required in driving and while turning. This small circuit can also be used for two wheeler even in bicycle. Main advantage of this circuit is, it will not only give a visual indicator but also give you a buzzer sound while turning left or right.
H-bridge using transistor
This project and circuit finds a huge application in the area of robotics to control motor direction. This circuit uses the basic concept of transistors as a switch. H-bridge using transistorTransistor with proper biasing can be used as switch, i.e. it can be used to toggle between the two states of a switch on or off. This configuration of transistor has been used in H-bridge to drive a motor in both clockwise and anticlockwise direction. This circuit derives its name from the English alphabet “H”, which closely resembles the circuit pictorially. The circuit based project can be divided into two parts. The first part explains the concepts behind the working transistor as switch and the second part the function and operation of H Bridge.

Transistor based Security Alarm
This circuit can be used to protect your valuable documents and jewellery from theft or intruder. Just put the switch under the mat or in front of locker so that when unauthorised person come it will walk over the switch and this will trigger the circuit and alarm start sounding. Main advantage of this circuit is you can use it in two places because both switches produce different sounds.In this circuit two switches S1 and S2 are used for two places like one can be used on front door and another can be used in front of locker. When S1 is pressed diode D1 connected to it start conducting because of that transistor T1 and T2 connected through resistor start conducting. Capacitor C1 is used to provide positive feedback to transistor T1 and T2 for oscillation. When S1 is pressed low frequency tone is generated indicating that intruder is present on door.
