Simple Arduino FM Transmitter Circuit
FM (Frequency Modulation) is a common way to send audio by radio signals. 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. This […]
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. It saves temperature data to SD card and later we can check data for […]
Metal Detector Circuit using Arduino
Metal detector uses electric field to find metal near it. Making Metal Detector Circuit using Arduino is fun for electronics lovers. We can make it using Arduino, CS209A chip, LEDs, buzzer and some other parts. LED and buzzer will show when metal is close. This project use CS209A chip with Arduino. CS209A is good chip […]
Building a Smart Pet Feeder Circuit using Arduino
Feeding pets can be easy and on time using automatic system. This project for Building a Smart Pet Feeder Circuit using Arduino and other parts like IC 7809, SG90 servo motor and HC-SR04 sensor to make simple pet feeder. Feeder work with distance sensor to give food so pet can eat on time without people […]
