The article details about an automatic water flow controller timer circuit which switches a valve mechanism ON/OFF as per a set predetermined timing sequence. The idea was requested by Mr. John Clarke. Technical Specifications I’ve seen your site and designs and wondered if you could help with a controller I’m trying to design to control […]
Newly Updated Circuit Projects:
Remote Controlled Ceiling Fan Regulator Circuit
In this article I have explained a few simple infrared TV remote controlled fan regulator or dimmer circuits using ordinary parts such as a 4017 IC and a 555 IC. The first concept uses a standard MOSFET based SSR for controlling the fan load and for easy and clean PWM signal operation from the IC […]
Toy Motor Circuit with Timed Reverse Forward Action
In this post I have explained a simple programmed reverse forward motor circuit which is used for accomplishing a toy application. The idea was requested by Mr. Matthew. Technical Specifications I am a new follower of your website which is a great resource! I need your help designing a circuit please. My daughter has a […]
LED Brake Light Circuit for Motorcycle and Car
In this post I have explained how to make and replace existing bulb type brake lights in vehicles with high efficiency LED lamps.The idea was requested by Mr. Awan. Technical Specifications I would like to build a brake lamp project using 1 watt high power leds, consisting of 12-15 leds. the leds would light on […]
How to Use Resistors with LED, Zener and Transistor
In this post I have explained how to use resistors while designing an electronic circuits using LEDs, zener diodes, or transistors. This article can be very useful for the new hobbyists who normally get confused with the resistor values to be used for a specific component and for the desired application. What is a Resistor […]
Battery Current Indicator Circuit – Current Triggered Charging Cut off
In this post I have explained about a simple battery current sensor with indicator circuit which detects the amount of current consumed by the battery while charging. The presented designs also have an auto cut off when the battery stops consuming current at its full charge level.. Why Current Drops as Battery gets Charged We […]
