Simple Level Voltage Detector Circuit Using LM741
Today we will be talking about the simple voltage level detector circuit. Its main purpose is to detect if the voltage rises above a certain point. Despite its simplicity, this circuit is an excellent way to learn about comparator circuits. We will use the LM741 OP-AMP as the main component of this circuit. This chip … Read more
Simple Bird Sound Generator Circuit
This bird sound generator circuit was one of the first circuits I built as a child. It is a fairly simple and small circuit made up of only a transistor and some common components like resistors, capacitors, an audio transformer, and a few others. The function of this circuit is straightforward: when pressing the switch, … Read more
