Hysteresis in Schmitt Trigger Circuit using IC 555
Schmitt Trigger is special type of comparator, which gives stable switching even if input signal is noisy or slow. We can use a 555 timer IC as a Schmitt trigger and it is also used in many projects. Furthermore, a Schmitt trigger provides two types of output: normal (non-inverting) and inverted square waves. Next, we […]
Simple Magnet Polarity Detector Circuit using Hall Effect Sensor
Simple Magnet Polarity Detector Circuit using Hall Effect Sensor is important for things like motor control, measuring magnetic field and for teaching. Also, this article show how to use APX9141 Hall Effect sensor to make easy and working magnet polarity detector. Red and blue LEDs show magnet north and south poles and it gives simple […]
Simple Arduino FM Transmitter Circuit
FM (Frequency Modulation) is a common way to send audio by radio signals, also many people like making FM transmitters with Arduino because DIY electronics is getting popular. In this project for Simple Arduino FM Transmitter Circuit we have used Arduino Uno, KT0803K FM module, 7809 voltage regulator and simple antenna to make FM transmitter. […]
Simple Micro SD Card Data Logging Circuit with Arduino UNO
Accurate data logging is very important in electronics and data work. This project for Simple Micro SD Card Data Logging Circuit with Arduino UNO show how to use micro SD card, IC 7809 and LM35 sensor to make simple data logger. Also, it saves temperature data to SD card and later we can check data […]
Simple Op-amp IC Tester Circuit
Op-amps (operational amplifiers) play an important role in electronics because they filter and amplify signals and process analog signals. Before using op-amp IC we must test it to ensure it works good and correct and to check op-amp fast and easy we have made a Simple Op-amp IC Tester Circuit Op-amp is like voltage comparator […]
