Current Corrected Af Amplifier The majority of modern AF power amplifiers drive the loudspeaker(s) with a voltage that is simply a fixed factor greater than the input voltage. It is fairly evident, therefore, that the power delivered by such amplifiers is inversely proportional to the loudspeaker impedance, since the cone displacement of a loudspeaker is […]
Arduino Voltmeter This arduino projects show how to make arduino voltmeter with your arduino. It use voltage divider concept to estimate the voltage input. Parts List; 1) 1x 16×2 parallel LCD display (compatible with Hitachi HD44780 driver) 2) 1x Arduino 3) 1x 10kΩ potentiometer 4) 5x 10kΩ resistor 5) 2x 2.2kΩ resistor 6) Jumper wire […]

4 Way Traffic Lights This circuit produces traffic lights for a “4-way” intersection. The seemingly complex wiring to illuminate the lights is shown to be very simple. Jan 28, 2016rare
Fan on off Control This circuit ( fan on off control ) lets you turn on/off a fan by just directing torchlight or other light toward its light-dependent resistor (LDR). The circuit is powered from a 5V power supply. Preset VR1 and a light-dependent resistor (LDR) work as the potential divider. Normally, the LDR’s resistance […]
Dancing Light – 555 circuits Here is a simple dancing light circuit based on NE555 (IC1) & CD4017 (IC2) . The IC1 is wired as an astable multivibrator to provide the clock pulses for the CD4017. For each clock pulse receiving at the clock input (pin14) of IC CD4017, the outputs Q0 to Q9 (refer […]
555 Circuits – Light Detector This circuit detects light falling on the Photo-cell (Light Dependent Resistor) to turn on the 555 and create a tone that is delivered to the speaker. Pin 4 must be held below 0.7v to turn the 555 off. Any voltage above 0.7v will activate the circuit. The adjustable sensitivity control […]
555 Circuits – Amplifier The 555 can be used as an amplifier. It operates very similar to pulse-width modulation. The component values cause the 555 to oscillate at approx 66kHz and the speaker does not respond to this high frequency. Instead it responds to the average CD value of the modulated output and demonstrates the concept of pulse-width modulation. The […]
