1.5V LED FLasher Using 3 Transistors
To make an LED function, a voltage source is required that exceeds the LED's forward bias voltage, which is typically greater than 1.5V (approximately 2V for red LEDs).
To effectively operate an LED, it is essential to provide a voltage source...
Led bar-dot level meter
A simple power meter can be configured to provide a bar or dot display for a hi-fi system. Green LEDs are used for levels 0 to 7, yellow for level 8, and red for levels 9 to indicate peak power....
Astable multivibrator with two LED
This is one of the basic circuitry of the electronics. The multivibrator astable shows two LEDs alternately light up with an adjustable speed. The circuit uses two transistors conduct alternately by the capacitors charged and discharged. The rate at which...
how to build bicycle back safety light
This circuit is designed to provide a clearly visible light using 13 high-efficiency flashing LEDs arranged in a pseudo-rotating order. Due to its low voltage, low battery drain operation, and compact size, the device is suitable for mounting on bicycles...
RC audio oscillator with 555
The transistor Q5 and the 1000-ohm resistor form the variable element necessary for controlling the frequency of the voltage-controlled oscillator (VCO) by limiting the charging current flowing into the 0.15 microfarad timing capacitor based on the forward bias applied to...
Alternating-led-flasher
The alternating LED flasher is a two-transistor oscillator with LEDs connected to the collector of each transistor, allowing them to light in sync with the circuit's oscillations.
The alternating LED flasher circuit utilizes a two-transistor oscillator configuration, which is a fundamental...
555 zinc-manganese batteries reduction charger circuit
The circuit utilizes a 555 timer as the core component to create an astable multivibrator. The oscillation period T is given by the formula T = 0.693 (R1 + 2R2) C1, which corresponds to an oscillation frequency of approximately 100...
555 timer IC
The 555 timer IC is an integrated circuit used in various timer, pulse generation, and oscillator applications. Its continued popularity is attributed to its ease of use, low cost, and good stability, with an estimated production of 1 billion units...
Dark-activated LED or Lamp Flasher
This circuit adopts the rather unusual Bowes/White emitter coupled multivibrator circuit. The oscillation frequency is about 1Hz and is set by C1 value. The LED starts flashing when the photo resistor is scarcely illuminated. The onset of flashing can be...
