Easy LED Photo Sensor Circuit With LM1458
This circuit utilizes a JFET to receive signals from an LED and buffer them. The output voltage is managed using an IC 1458 or LM1458, which provides approximately 7 volts in darkness and experiences a drop of about 2 volts...
valentines day gift
This year for Valentine's Day, an electronic project was created for Caroline. Initially, an attempt was made to construct an animated LED heart using a joule thief circuit with a single AA battery; however, difficulties in creating a suitable air...
LED Ultraviolet exposure box
The LEDs are OSSV53E1A from OptoSupply and they have a 140° angle. This means that the first plane with uniform density can be obtained at a shorter distance from the LED, for a given spacing between LEDs which means smaller...
Darkroom Timer Circuit
The electronic darkroom timer is constructed using a 555 oscillator/timer, a pair of general-purpose transistors, a buzzer, and an LED. The 555 timer (U1) is set up as an astable multivibrator, functioning as a free-running oscillator. The frequency of the...
555 IC Linear Ramp (Sawtooth) Generator/Oscillator
The voltage Vc1 increases linearly when the pull-up resistor RA in the monostable circuit is replaced with a constant current source, resulting in a linear ramp. The circuit for generating the linear ramp and the corresponding waveforms are illustrated in...
electronic dice
The 555 astable board utilizes a 555 timer configured in astable mode, producing a square wave or alternating high and low signals. The frequency of the signal is determined by capacitor C1 and variable resistor R3. This design is intended...
Car Wiper-Speed Controller
This 12V wiper speed controller circuit utilizes a 555 timer. It is a straightforward and practical circuit that can be installed in any car.
The 12V wiper speed controller circuit is designed to regulate the speed of windshield wipers in automotive...
Light emitting diode circuit of the temperature control
The circuit consists of two light-emitting diodes (D1 and D2) whose operation is controlled by the ambient temperature. A temperature sensor, the LM35, generates an output of 10 mV for each degree of temperature increase. A reference potentiometer, R2, is...
Simple Audio amplifier Using Transistors
Construct a basic audio amplifier utilizing transistors. While integrated circuit (IC) designs are available for this purpose, the intention is to use transistors to gain practical knowledge about their amplification capabilities. The article "Amplifier Basics - How Amps Work (Intro)"...
