Digital Code Lock Circuit using Arduino
Everywhere in the globe, security is crucial and it presents a significant challenge for locations that maintain secrecy. This initiative contributes to increased security. This project uses an Arduino, a tiny microcontroller to create a basic lock. Using an Arduino UNO board, a keypad module, a buzzer, a 16×2 LCD, a BC547 transistor and a […]
Simple Thyristor Switching using Snubber Circuit
In this article thyristors are switches used in power electronics to regulate high voltage and current. They are often referred to as SCRs (Silicon Controlled Rectifiers). A gate signal activates them, and the only way to turn them off is to stop the current flow. On the other hand, voltage spikes and abrupt current fluctuations […]
Simple Crowbar Circuit
In electronic devices, a crowbar circuit is a safety feature that guards against high voltage spikes and surges damaging circuits. It functions similarly to a fuse, but instead of just burning itself out, it quickly cuts off electricity and stops more harm by causing a short circuit. Usually, it makes use of a thyristor SCR […]
Simple Over Voltage and Reverse Voltage Protection Circuit
Your electronic gadget is protected from damage caused by inappropriate voltage application by a basic over voltage and reverse voltage protection circuit. When compared to utilizing simply a diode, this circuit using a P channel MOSFET FQP47P06 provides a more reliable option. Simple single diodes can be used to protect the circuit against reverse voltage, […]
