In this project, we will be making CD4033 counter circuit. a mod-100 counter circuit (0 to 99). We are using a 555 timer, CD4033 counter 7 segment display, and some other components. It is a very simple counter circuit. Counter circuits are often used to count objects, people, and many other things. Components required: 555 […]
Water Level Indicator and Pump Controller using Arduino
Making a water level indicator and pump controller using Arduino is a very good idea. We can fully automate our water supply system using sensors, electronics, and some programming knowledge. The water pump controller which we are making automatically switches ON and off depending on the level of water. Also, it displays the level of […]
Ultrasonic Sensor Without Arduino using 555 timer
Hey folks, have you used an ultrasonic sensor in your projects! Do you know how it works? In this project, we will use an ultrasonic sensor without Arduino for object detection. We will interface ultrasonic sensor with a 555 timer to control a DC motor. How ultrasonic sensors work? As the name suggests an ultrasonic […]
Seven Segment Display with Arduino Interfacing 0 to 99 counter
Hey folks, in this article we will see what is a seven-segment display with Arduino Interfacing. How to connect a seven-segment display directly to the Arduino without any decoder IC. Also, we will code Arduino to count Arduino from 0 to 99 on seven segment display. Let’s get started. What is a seven-segment display? A […]
LM380 Audio Power Amplifier Circuit And it’s Working
The LM380 is an audio power amplifier for consumer application. Its internal gain is fixed to 14dB in order to keep the system cost minimum. A unique input stage allows inputs to be referenced with the ground. The output gets automatically self-centered to one half the supply voltage. The output amplifier is short circuit proof […]
Peak Detector Circuit using OPAMP
Here is the circuit diagram of a peak detector circuit using opamp. A peak detector circuit is used to determine the maximum (peak) value of an input signal. It stores the maximum value of the input signal for a very long interval of time. In many applications we need to measure the maximum value of […]
