To begin with, this project uses RF 433MHz module and one Arduino work like transmitter and other like receiver. When we press button on transmitter side, LED on receiver side go ON or OFF and also this RF Transmitter Receiver Circuit with Arduino Uno is very simple. In addition, circuit is good project for new […]

Single Transistor Theremin Oscillator Circuit
Theremin is one very old electronic music instrument, which make strange space type sound without touching any part; when human hand move near antenna or plate then the pitch of sound changes. In addition, this happen because hand change the capacitance value near the circuit. Also, in this article we will show very small and […]
AM Radio Circuit using Transistors
This article show how make AM Radio Circuit using Transistor, as it uses easy parts like transistor, capacitor, resistor and inductor. Also, parts are easy to find and good to learn basic radio frequency RF, catch signals and to make sound louder. Circuit catch medium wave AM signals and changes AM signal to sound and […]
Low Cost AM Radio Receiver Circuit
This cheap and easy Low Cost AM Radio Receiver Circuit uses simple parts to make, it helps us get normal AM radio signals and then it uses 2N3904 transistor and LM386 amplifier to find and make AM signals louder. Also, circuit is good for beginners and people who want to learn about radio and electronics […]
