TRIAC Test Circuit

TRIACs: A triac is a bidirectional, three-terminal dual, back-to-back connected (SCR) switch. This device will conduct current in both directions when a small current is constantly applied to the Gate. If the gate is given a small, brief, current during any instant of a cycle, it will

SCR Testing Circuit

SCR-SILICON CONTROLLED RECTIFIER The SCR-Silicon Controlled Rectifier is a semiconductor device that is a member of a family of Thyristors. It is a 3-leaded device and when a small current enters the Gate, the thyristor turns on, and stays on. It only conducts current between Anode and

MOSFET Testing Circuit

MOSFET means Metal Oxide Semiconductor Field Effect Transistor. FETs operate exactly the same as a normal transistor except they have different names for the input and output leads and the voltage between the gate and the source has to between 2v to 5v for the device to

DC motor (BO) Battery Operation

DC motor (BO) Battery Operation. Dc motor converts electrical energy into mechanical energy.  Why DC gear motor used in robot Motor control circuit. DC MOTOR concept is where gears reduce the speed of the vehicle but increase its torque is known as gear reduction. In DC motor

How Does Sensor Work

SENSOR: The sensor is a transducer type, it is used to sense or detect events or changes in physical quantities and gives a corresponding analog output. TYPES OF SENSOR: 1. IR sensor. 2. proximity sensor. 3. Temperature sensor. 4. Pressure sensor. 5. Light sensor. 6. Fires sensor.

DC Motor Dual H-Bridge IC-L293D

DC (Direct Current) Motor for both way motion like Clockwise and Anticlockwise of one DC Motor, an H Bridge circuit is needed. For both way motion of 2 motors a Dual H-Bridge IC named L293D can be used. L293D IC Details: 1. Voltage Range: DC4.5V to 36V.
