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 use them.
I found some nice instructables about the TEA 5767 most of them use a NOKIA LCD Display and some buttons to change the frequency or auto scan…., I try those first to learn how to use the TEA 5767, but I didn’t like ithem so much it was to boring for me just copy another work and so I think what else could I build with such an TEA 5767 and an Arduino plus some other parts.
I like LED’s, to be honest I’m addicted to those LED’s. Trust me everything with LED is funny.
I remember those old FM Radios with an “knob” to turn around for adjusting the frequency and showing the frequency on an bar graph like display.
I owned one long time ago there was the indicator for the frequency was a single LED.
So the Idea was born for my own FM radio….
1. it should use the TEA 5767 Modul.
- easy to get and a lot of material about it is avaiable
- cheap I got mine for about 1 (5x for 5,33)
- easy to handle after you solder it to a little perfboard
2. it should be controlled by an Arduino or something similar
- of course it is easy to prototype, you can just make some tests with an Arduino UNO and a breadboard
- easy to use IDE, much more easyer then the AVR Studio Software I used a long time ago.
- in my final Design it will be a single ATMEL 328P with the most important parts only not the whole Arduino.
- I got those ATMEL 328P also cheap at banggood.com normaly 5 for less then 10 they are not preprogrammed with the Arduino bootloader but this is easy to do, I use my handy USBAsp.
3. 2 x 74HC595 to controll 16 LED’s
- as allready told I like LED’s so much
- ever more LED’s is better but 16 should be enough
4. one LED for Power
- never can have enough LED’s
- maybe I can use it later for something else
5. a rotary Encoder
- for adjusting the frequency totaly oldstyle just rotating the knob
- it is one with a click switch never now when you can use it
5. 3 - 4 normal tactile switches
- I want to use them for Station Memory
- in my first “firmware” the frequency for the stations will be hardcoded until I understand how to use eeprom on the atmega”
