ElectroSuite.com - Twilight Lamp Blinker. The entire circuit of twilight lamp blinker is designed and fabricated around LDR (Light Detector Resistor) and IC CD4093 (IC1). The preset VR1 is used to control brightness.
ElectroSuite.com - 5×7 LED Display Driver LTP 747HR. The display has 7 row pins and 5 column pins. Each one of its 35 LEDs is connected across an intersection of a row pin and a column pin. So, a single LED can be lit by applying a positive voltage to its column and grounding its row.
ElectroSuite.com - 6 LED Chaser PIC 16F84.
ElectroSuite.com - 6V Ultra Bright LED Chaser. This is a spectacular but completely useless project. It lights Ultra-Bright LEDs in a sequence and each LED flashes brightly very briefly. (more…)
ElectroSuite.com – The Double 555 Traffic Light Schematic animation shows the lighting sequence and this follows the Australian-standard.
ElectroSuite.com – 555 Flashing Railroad Lights. This circuit flashes two red LEDs for a model railway crossing.
ElectroSuite.com – 1V5 LED FLASHER. This will flash a LED, using a single 1.5v cell. It may even flash a white LED even though this type of LED needs about 3.2v to 3.6v for operation. The circuit takes about 2mA but produces a very bright flash.
ElectroSuite.com – 7107 Led Display Digital Voltmeter. The circuit employs the ADC (Analogue to Digital Converter) IC CL7107 made by INTERSIL.
ElectroSuite.com – This 4017 7 Led Light Running Adjust Speed circuit can adjust the speed of the led light as needed. Makes this circuit can be used more versatile.
ElectroSuite.com – Driving 2 Color LED. Some 3-leaded LEDs produce red and green. This circuit alternately flashes a red/green bi-coloured LED.
ElectroSuite.com – 4001 NOR Gate SR Latch. The 4001 integrated circuit is a CMOS quad NOR gate, identical in input, output, and power supply pin assignments to the 4011 quad NAND gate.
