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 […]
Long Range IR Transmitter Circuit
Compared to basic circuit this Long Range IR Transmitter Circuit can send IR light farther using easy parts, also its main idea is to make IR LED blink light in pulses. Furthermore, most IR receivers catch specific frequency made by IC 4047. Using more LEDs together or stronger LED gives more IR light, so with […]
