Simple Micro Flasher Circuit using IC CD 4093
Simple Micro Flasher Circuit using IC CD 4093 is easy way to make LED blink for many indicators, also CD 4093 has four NAND Schmitt trigger gates inside. In addition, circuit runs on 6V battery and need few parts only which is very simple and good and its flashing happens because one NAND gate turn […]
PWM Based Lamp Brightness Controller Circuit
The circuit control lamp brightness with PWM, and it is good for adjusting incandescent lamp light; also it uses 555 timer as astable multivibrator to control low-power lamp. PWM controls power to lamp and changes brightness easily and this PWM Based Lamp Brightness Controller Circuit runs on 6V battery and works for many lighting needs. […]
Rotating LED Array Circuit using IC 555
The Rotating LED Array Circuit using IC 555 works like an LED flasher and creates a rotating light effect when we arrange the LEDs correctly, hence, this simple project is easy to build and delivers impressive results. Furthermore, we can use this circuit for decoration, emergency light or alert and this circuit gives two IC […]
PWM LED Ramping Circuit (Slow Bright, Slow Fade)
PWM LED Ramping Circuit (Slow Bright, Slow Fade) make LED light go bright slowly and with not sudden ON/OFF, as this circuit is good for signal, decoration and for soft light. Also, it uses 2× IC 555, LM393, 2N7000 MOSFET for smooth change and the circuit works best with 3 to 12V power with 6V […]
Automatic Night Lamp Circuit with Photocell
Automatic night lamp use photocell to check light or dark; when dark the lamp is ON and when light the lamp goes OFF. This type of circuit is good for street, garden and security lights and also the parts used in circuits are LDR (ORP12), op-amp (uA741), relay which controls the AC lamp. Also, low […]
