Why did the author choose a PIC microcontroller instead of Arduino?

The author had a stockpile of these ICs in their parts bin and noted that most existing digital FM radio tutorials use Arduino.

How was the AR1010 library adapted for the PIC microcontroller?

The author used the Ar1010 Arduino Library by adamjansch/AR1010lib and ported it to be compatible with the MikroC for PIC IDE.

Does this design require an external oscillator?

No, the design uses the internal 32 mhz clock of the PIC16F1847 MCU.

How are the modules connected to the main board?

The modules are soldered together using jumper wires rather than headers and connectors.

What tools are required to build this project?

Tools include a soldering iron, long nose pliers, digital multi tester, exacto knife, cutter plier, glue gun, 3D printer, and a Microchip PICKIT 3 Programmer/Debugger.

What type of power source is used for the radio?

A 18650 battery salvaged from an old laptop battery pack is used in conjunction with a 3V to 5V step-up USB charger boost converter.

Summary of PIC16F1847 and AR1010 Based FM Radio Music Box

This project details the construction of a portable Digital FM Radio using a PIC16F1847 microcontroller and an AR1010 receiver module. The author chose the PIC chip over Arduino due to existing inventory, despite the prevalence of Arduino tutorials. The device features a MAX7219 7-segment display for frequency output and a PAM8403 audio amplifier. It is powered by a salvaged 18650 battery via a boost converter, housed in a custom 3D-printed enclosure, and controlled by three push buttons.

Parts used in the Digital FM Radio Box:

PIC16F1847 Microcontroller
AR1010 FM Radio Receiver Module
MAX7219 8 Digit 7 Segment Led Module
PAM8403 5V DC Audio Amplifier Board
3V to 5V 1A Step Up Module USB Charger Boost Converter
18650 Battery (salvaged from old laptop)
3 pcs. Push button micro switches
AMS1117-3.3 Voltage Regulator
4.7Kohm Resistors
10uf / 16v electrolytic capacitor
Custom 30mm x 30mm perf board
3D Printed Box Enclosure

This is my first Instructable post. I made a Digital FM Radio box using this cheap AR1010 FM Radio receiver module that I bought from Ebay and a PIC16F1847 Microcontroller from MICROCHIP. Why PIC's? Why not use Arduino? Because i have bunch of these IC's stocked in the parts bin. And also because most of the Digital FM Radio instructables and tutorials use the arduino.

Let's Make it.....

Step 1: Parts and Tools Needed...

The Basic parts are the Following:

The Brain - Microchip Pic16F1847
Digital FM Radio Receiver - AR1010 Module
Display - MAX7219 8 Digit 7 Segment Led Module
Audio Amplifier - PAM8403 5V DC Audio Amplifier Board 2 Channel 2*3W Volume Control
Power/Charging - 3V to 5V 1A Step Up Module USB Charger Boost Converter w/ 1pc. 18650 battery salvaged from old laptop battery pack.
Interface - 3 pcs. push button micro switches
3D Printed Box Enclosure - STL files link here

Tools to Use:

Soldering Iron
Long Nose Pliers
Digital Multi tester
Exacto Knife
Cutter Plier
Glue Gun
3D Printer
Microchip PICKIT 3 Programmer/Debugger

The Schematic is drawn using the Free version of Autodesk Eagle PCB design software.

The parts list for the main board are the following:

1 pc. PIC16F1847 MCU PDIP-18

1 pc. AMS1117-3.3 Voltage Regulator SOT223

6 pcs. 4.7Kohm / 0.5 watt Resistors

1pc. 10uf / 16v electrolytic capacitor

All these parts are mounted on a custom cut 30mm x 30mm single sided perf board to fit it inside the casing. The PIC Mcu is mounted on the top side the board. The AMS1117-3.3 SMD regulator and the AR1010 module are soldered on the copper side .

There is no external Oscillator because i used the internal 32 mhz clock of the PIC16F1847 MCU. I didn't use any headers and connectors to connect the modules, they are soldered with jumper wires. The headers are for serial debugging and ICSP programming.

Step 3: CODE

The code is written and compiled using the Code Limited version of the MikroC for PIC.

I used the Ar1010 Arduino Library of adamjansch/AR1010lib and ported it to be compatible with the MikroC for PIC IDE.

I wrote my own Max7219 library.

Step 4:

Updated the Source File to include the MAX7219 library...
