A transceiver is a wireless communication device which has its own transmitter and receiver units built-in for communicating with another similar device at some distant location. The user on both sides with the unit has to switch from transmitter to receiver and vice versa while speaking and hearing to each others conversation respectively. Introduction In […]
Newly Updated Circuit Projects:
Traffic Light Controller Circuit [Signal Red, Green, Amber]
A traffic light controller circuit can be used for controlling the sequential illumination of the RED, ORANGE and GREEN traffic signal lamps, by maintaining appropriate delays between the illumination sequence. In real traffic signal light system we all have seen how the red, orange and green lamps switch ON/OFF in sequence with specific amount of […]
Ultrasonic Fuel Level Indicator Circuit
An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact, through ultrasonic waves, is called an ultrasonic fuel level sensor In this post I have explained how to build a simple fuel tank level indicator circuit using Arduino and ultrasonic sensors. In every vehicle […]
PIC Tutorial- From Registers to Interrupts
Before getting into the minute details of PIC programming, it would be first important to learn a few good programming methods. Understanding Registers To begin with suppose you type a ;(semicolon) at any point of the program, all’s that come after this semicolon would get ignored by the compiler, until of course the carriage get’s […]
Fading an LED ON/OFF – Arduino Basics
In this post I have explained a basic Arduino function where I have explained the process of fading an LED ON/OFF through some basic code implementations. Creating a Fading Effect We see how to use an analogwrite() function in order to implement a fading ON/OFF of an LED. The function incorporates PWM pulses across a […]
Converting Analogue to Digital (Analogue Read Serial) – Arduino Basics
In this Arduino basics I have explained the code implementation procedure wherein an external analogue signal is fed to the Arduino analogue input and translated or converted into a correspondingly proportionate digital readout. Here we employ a variable resistance in the form of a pot as the analogue signal source. Analog Read Serial In this […]
