Battery Voltage Level Indicator Circuit using 3 LED
To begin with, Battery Voltage Level Indicator Circuit using 3 LED is small circuit to show battery voltage with 3 LED. Here, one LED for low, one for medium and one for full charge, which helps to know battery is good or need charging. Thus, we can easily make this circuit and use it for […]
How to Build a Two LED Temperature Indicator Circuit
This article shows how to build a Two LED Temperature Indicator Circuit, as it is easy and cool project and we can use this circuit for many things, like checking water shower when it is not too hot, so no damage can happen. Furthermore, also be sure computer parts, amplifier, heater and even car water […]
LED Strobe Light Circuit
This article show how to make one LED Strobe Light Circuit which uses famous chip named IC 555. Users use knobs and resistors to control light intensity and blink rate, while one resistor also controls the power connected to the LED. Also, this project uses a special, high-power switch, if possible, use this same type of […]
Simple Water Level Indicator Buzzer Circuit
This Simple Water Level Indicator Buzzer Circuit show how much water is inside the tank and also it make beep sound like alarm when water become too high or too low. Also, we can make this circuit using transistor and some other small electronic parts, however, it only beep when water touch two metal pieces […]
