An ammeter is an instrument used to measure current flow in a circuit, which is measured in amperes. In a Digital ammeter, we measure the voltage across a shunt resistance, which is series to...
L293D Motor Driver L293D is a 16 pin motor driver IC consist of quadruple half H drivers. It can simultaneously control the direction and speed of two DC motors. L293d is a suitable device...
Solenoid Valve A solenoid valve is an electromechanical valve used to control the flow of fluids. It has a simple valve Open and Close mechanism operated by a solenoid. Solenoid valves are widely used in...
Automatic irrigation is a concept of controlled watering of plants without any manual operations so as to maintain a water level ideal for its cultivation. For an automatic plant watering system, we can adopt...
In this project, the movement of the servo shaft in the clockwise and anticlockwise direction is controlled by two pushbuttons using Arduino; refer: How to use a servo with Arduino. In the circuit, the...
Ultrasonic braking is a method of collision avoidance system that can automatically brake the vehicle before an impact. That is whenever any obstruction came in front of the vehicle the system disengages the power...
LED Chaser An LED chaser has an output of a Ring counter circuit. Where the high state at an output pin shift from one pin ( a bit) to another, having only one output...
Ultrasonic water level indicator mainly consists of an HC-SR04 ultrasonic module, which is used for non-contact distance readings. Ultrasonic water level sensing is a non-contact level measurement technique. For measuring water level, place the ultrasonic...
An ultrasonic distance measurement is a non-contact distance ranging technique. It is simply based on using the echo. That is calculating the distance by analysing the time required for the propagation of sound waves....
Here is a simple voltmeter project using Arduino to measure and display DC input voltages. It can be used to measure battery voltage, sensor readings, etc. It can be even used for measuring higher...
