Hi guys, my name is Pedro Castelani and I’m bringing you my first instructable: building a two way radio with arduino for, well, whatever you need it for. In this project, we will make two seperate circuits which will act as both reciever and transmitter. The most important components are two arduino boards (all of […]
I recently dug up my old RC transmitter and receiver and thought “How can i control my arduino with this?” so i powered on my scope to see what was going on at the receiver. Sure enough, it was sending out the standard PWM signal that servos use. Now I just needed something to control. What’s easy
Recently, I came across RDA5807 module which is an FM Radio Tuner in a very tiny package. It is very cheap and uses I2C protocol for communication which means that only two wires will be required to talk to the IC. Less wiring! My mom used to listen to the radio every day while cooking food before
This project is without doubt the most complex I have undertaken, with sixteen IV-11 VFD tubes, two Arduino Mega cards, ten LED Neon light circuits, a servo, an electromagnet, two MAX6921AWI IC Chips, five DC power supplies, a HV power supply, two DC Volt meters, a DC Amp meter, FM stereo radio, 3W power amplifier,
Update 16.04.2015 just thought how would a “cool” kit look a like, so I get an altoids tin box eat all the thinks inside and put all necassary parts inside. 😉 a new project from good old Germany. I got some of those very popular FM radio modules at banggood.com, and was thinking how to
This article shows you how to build a small radio station at home and share music with others. The station can also be used for making announcements in colleges, industries, hospitals, schools and other places using a condenser mic amplifier circuit. In this project an FM transmitter V2.0 module is used, as shown in Fig.
The most important part is the construction of a functional sample of a Arduino Uno software-defined one transmitter. After agreement with the supervisor and current options, she was elected concept with SI4713 digital circuit… Electronics Projects, Arduino Uno FM AM Transmitter Circuit SI4713 “arduino projects, microcontroller projects, “ The most important part is the construction of a functional sample

Solar charging, via the panel on the back. * 12 position switch to select channel number * Seek up / seek down controls and ‘store’ button * RDS display of call sign * Frequency display * Battery voltage display * Solar charging current display The software still needs a bit of attention. Its fine if
Interfacing a RC radio to a microcontroller is a bit of a pain, especially if you want a lot of channels, because you have to time each channel’s output individually. An AVR only has one 16 bit timer with two compare channels, so either you can only use two channels at full resolution or you
SOS is the commonly used description for the international Morse code distress signal (· · · — — — · · ·). [read more on wiki] Requirements: 1) Arduino 2*) 8 Ω speaker 3*) 150 Ω or similar resistor 4) 5mm RED LED 5) Hook-up wires 6) Any breadboard * Ω = Ohms Step 1:
