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
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 (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.
DIY – Means Do It yourself. Make simple and Low cost LFR-Line Following Robot using AT89c51 Micro controller IC. A line follow robot is autonomous robot that follows here my robot either BLACK LINE IN WHITE BACKGROUND or WHITE LINE IN BLACK Background. The motor drive circuit
What is 1N4001 means: 1N4001 series diodes are 1 Ampere current handling general purpose rectifier diode. 1N is stands for American standard semiconductor (Generic name) with ONE JUNCTION. 400X Series like 4001,4002 to 4007 is indicates the voltage, current and power rating of the diodes. 1N=
A photo diode is a p-n junction or PIN structure. When a photron of sufficient energy strikes the diode, it excites an electron, thereby creating a free electron (and a positively charged electron hole). This mechanism is also known as the inner photoelectric effect. If the absorption occurs in the junction’s depletion region, or one diffusion
The sensitivity of photo diode can be increased to larger value about 100 times by adding a junction resulting in a NPN transistor. The photo transistor is usually connected in a common emitter configuration with base open. The illumination (Radiation) is concentrated on the region near the emitter base junction. A
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input)
