IC 74193 is a 4-bit presettable synchronous MODULO-16 Up/Down binary counter IC. IC74193 has two separate clock input pins to count up and count down, the output is synchronous with the clock inputs. The separate Terminal Count Up & Terminal Count Down are provided which is useful for designing higher counter or cascading the IC74193. The […]
In this tutorial, you will learn how to make this over-voltage protection circuit. It requires fewer components and is very effective in overvoltage conditions. It will cost you around 3$ to 5$ depending on the quality of components. Overvoltage occurs when the voltage in a circuit is raised above its upper design limits. This condition […]
Controlling the brightness of an LED or blinking it continually by passing various delays with PWM (Pulse Width Modulation) it might be your first Raspberry Pi 4 learning experience. In this article, we perform three activities which are, Turning On & Off LED. Blinking it using PWM at different frequencies. Controlling the brightness of the […]
This is an adjustable over-current and Short circuit protection using LM358 OPAMP. In this article, we will see how you can make short circuit protection using LM358 OPAMP. A short circuit occurs when the current flowing in a circuit bypasses the load and flows from a path having the least or zero resistance. We can […]
In this tutorial, we will see how to make a short circuit protection using Relay. Many times accidentally terminals of batteries and other power supplies get short-circuited. Due to this, they get hot and start degrading. In the case of lithium-ion or lithium-polymer batteries, they may catch fire due to short-circuit or even get blast. […]
Control your home lighting and fans using ESP32 Home Automation Project based on Google Assistant Blynk and IFTTT. This is very easy to set up, simple to operate, and a cost-effective system for your home residence and even offices. You can operate it via google assistant, manual buttons, and Blynk application. What are the things […]
