This Simple Over-Temperature Warning Indicator Circuit uses an LED to indicate excessive temperature, as it uses only a few easily available components, making the circuit simple, low cost, and easy to build. The circuit turns ON an LED when temperature rises above a set level like 45°C – 55°C and therefore, it is useful for […]
Arduino Flash Trigger Circuit with Sound Sensor
Nowadays, electronics projects are becoming very popular, especially Arduino based projects are easy to build, because of this the beginners also feel confident. In this project, an Arduino monitors the sound sensor and triggers the camera flash when it detects a sound. So Arduino Flash Trigger Circuit with Sound Sensor is very useful for high […]
Solar Cell Based Camera Flash Trigger Circuit
Photography flash units need correct timing; however, many old flash units do not have trigger input, so a Solar Cell Based Camera Flash Trigger Circuit is useful, as this circuit is very simple as it uses very few components and also it does not need any battery. The circuit operates by detecting light, when the […]
12V Boost Converter Circuit from 3.3V to 5V Supply
Nowadays, many electronic projects need higher voltage, however, the available supply is very low for example 3V or 3.3V batteries are common. But many circuits need 12V so, here we have designed a 12V Boost Converter Circuit from 3.3V to 5V Supply, as this circuit increases low DC voltage to high DC voltage and therefore, […]
Boost Converter Circuit From 5V to 12V using Transistors
Many electronic projects need 12V power, but sometimes only 5V supply is available, for example from USB, logic board or microcontroller; So, here, this Boost Converter Circuit From 5V to 12V using Transistors is useful which converts 5V DC to 12V DC. This circuit uses simple components such as transistors and an inductor, making it […]
