Top 3 555 Timer Based projects made on Custom made PCBs

555-timer IC (integrated circuit) is used to generate an accurate delay and oscillations in electronics. It works either in monostable, bistable, and astable mode. The IC gets its name because of the three 5Kohm resistors present in the circuit. The basic constructional features include a voltage divider network, comparators, a flip-flop, transistors, and an inverter.
Now let’s look at some of the best 555 timer-based projects made on Custom made PCBs designed through PCBWay.

A standard LED controller offers flickering or whirring problems while adjusting the brightness of an LED. This effect is visible in cameras while recording a video. This 555 timer-based controller eliminates the flickering. The controller is crafted on a high-quality PCB, ordered from PCBWay. It uses a transistor and a potentiometer to adjust the brightness of the LED.

COMPONENTS REQUIRED

10K Potentiometer
Capacitors: 10nF, 470uF, 1.5nF
1K Resistor
Diodes
Transistor

While working on any electronic project, you may have witnessed noises from the circuit. The noises may be irritable. But, ever thought of converting these noises into a good piece of music? It feels weird, right? Well, this project is the implementation of such an idea.
The PCB board ordered from PCBWay uses a 555-timer. Along with binary counter, NAND gate to create and manipulate tones. Four potentiometers tune the RC network. In addition to that, one potentiometer varies the frequency of the 555 timer circuit. And one master potentiometer controls the volume.

It is a simple project in which the timer works in monostable mode. It precisely adjusts a delay of 1-100 sec using a potentiometer. The timer can be manually reset using a pushbutton provided on the PCB board. A red LED indicates when the circuit turns ON. While a green LED indicates when the relay turns ON. When the timer starts, the relay turns ON, which connects to a high power load such as a light bulb or a water pump. The capacitors in the circuit filter noise present in the main supply.
