Workflow of making Master ,salve boards and construction

i have decided to make the boards using the nRF communication to triger the condition and want to use the nRF to get the data so i have decided to make the my board named scitechRFduino

What is nRF24L01

The nRF24L01 is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM (Industrial, Scientific and Medical) band. With peak RX/TX currents lower than 14mA, a sub μA power down mode, advanced power management, and a 1.9 to 3.6V supply range, the nRF24L01 provides a true ULP solution enabling months to years of battery lifetime when running on coin cells or AA/AAA batteries.

The module can use 125 different channels which gives a possibility to have a network of 125 independently working modems in one place. Each channel can have up to 6 addresses, or each unit can communicate with up to 6 other units at the same time.

The power consumption of this module is just around 12mA during transmission, which is even lower than a single LED. The operating voltage of the module is from 1.9 to 3.6V, but the good thing is that the other pins tolerate 5V logic, so we can easily connect it to an Arduino without using any logic level converters.

Production of the Scitechduino

As i am good with electronic design using the eagle software this week also ,i have used the eagle to design my scitechRFduino

The design files exported to the png format to make the board using the modela same as Electronics Production

for the nRF we need a 3.3v power sourcee as input and for powering up you need a 5v current and so i have decided to make a power board for it separtely

Milled the power board using the modella

Now soldering of these boards

Soldering of boards

as this now we are at week16 i have got good at the soldering skills so i have made the two boards soldering very fastly

programming and output

Programming for the communication between the two boards with nRF Communication one as the transmitter and other as the reciver ,i have used the pin connections to nRF24L01 pin connection is as follows (note that you may need to connect it differently if you use a different arduino board, refer to the RadioHead library):

#include  <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
int msg[1];
RF24 radio(8,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int SW1 = 7;
void setup(void){
 Serial.begin(9600);
 radio.begin();
 radio.openWritingPipe(pipe);}
 void loop(void)
 {
 if (digitalRead(SW1) == HIGH)
 {
 msg[0] = 111;
 radio.write(msg, 1);
 }
 }

#include  <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
int msg[1];
RF24 radio(8,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int SW1 = 7;
void setup(void){
 Serial.begin(9600);
 radio.begin();
 radio.openWritingPipe(pipe);}
 void loop(void)
 {
 if (digitalRead(SW1) == HIGH)
 {
 msg[0] = 111;
 radio.write(msg, 1);
 }
 }

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
int msg[1];
RF24 radio(8,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int LED1 = 3;
void setup(void){
 Serial.begin(9600);
 radio.begin();
 radio.openReadingPipe(1,pipe);
 radio.startListening();
 pinMode(LED1, OUTPUT);}
 void loop(void){
 if (radio.available()){
   bool done = false;    
   while (!done){
     done = radio.read(msg, 1);      
     Serial.println(msg[0]);
     if (msg[0] == 111){delay(10);digitalWrite(LED1, HIGH);}
     else {digitalWrite(LED1, LOW);}
     delay(10);}}
 else{Serial.println("No radio available");}}

#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
int msg[1];
RF24 radio(8,10);
const uint64_t pipe = 0xE8E8F0F0E1LL;
int LED1 = 3;
void setup(void){
 Serial.begin(9600);
 radio.begin();
 radio.openReadingPipe(1,pipe);
 radio.startListening();
 pinMode(LED1, OUTPUT);}
 void loop(void){

   bool done = false;    
   while (!done){
     done = radio.read(msg, 1);      
     Serial.println(msg[0]);
     if (msg[0] == 111){delay(10);digitalWrite(LED1, HIGH);}
     else {digitalWrite(LED1, LOW);}
     delay(10);}}
 else{Serial.println("No radio available");}}

Output

i was able to on the LED on the reciver using the transmitter

Hero Shot

Now here we comes to the Hero Shot of this Week
