Simple Water Alarm Circuit Diagram
It worked by sounding an alarm when the water level rose to the set level. So we can close the water valve in time and prevent an overflow. Read more
LED Blinking Circuit Flashing Bicycle Taillight
Today we will be learning electronics through creating a simple circuit again. This time, it is the led blinking circuit as Bicycle Taillight. That will emit a flashing red light on the back of our bicycle to increase safety at night. We have designed this circuit with basic electronic principles in mind, so there would … Read more
What is a Buck converter circuit
This is a DC to DC Buck converter working principle. We often use it as a step down DC to DC converter circuit. Because it is a switching mode power supply. Read more
Experiment with Parallel Transistors for More Current
Let’s learn how to use several small transistors in parallel to increase the current so that the transistor can drive bigger loads. Read more
