Hacks of Electronics
Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
IC74163 Integrated Presettable Synchronous 4-bit Modulo-16 Up counter. The IC is a synchronous counter as all 4 flip-flops are integrated into the same chip & they receive the same clock pulse (clock signal). The IC74163 is a completely programmable binary counter due to its four preset inputs, which allow it to begin counting with any […]
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 LED. […]
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. […]
