This example flashes one of two LEDs, depending on the state of a 2-way switch.
The signals used for this example are listed below:
| Signal | LPC4330 PIN NAME | BAM210E | BAM210 | BAM200E | BAM200 | Used for |
| D0 | P6_5 | J9-1 | J9-1 | S2-5 | S2-5 | Red LED |
| D1 | P6_4 | J9-2 | J9-2 | S2-4 | S2-4 | Green LED |
| D2 | P1_7 | J9-3 | J9-3 | S3-7 | S3-7 | Push-button |
The following schematic can be used to build the circuit with a BAM210E or BAM210.
Schematic for example 03-03
/*Program Example 3.3: Flashes one of two LEDs, depending on the state of a 2-way switch
*/
#include "mbed.h"
DigitalOut redled(D0);
DigitalOut greenled(D1);
DigitalIn switchinput(D2);
int main()
{
while(1) {
if (switchinput==1) { //test value of switchinput
//execute following block if switchinput is 1
greenled = 0; //green led is off
redled = 1; // flash red led
wait(0.2);
redled = 0;
wait(0.2);
} //end of if
else { //here if switchinput is 0
redled = 0; //red led is off
greenled = 1; // flash green led
wait(0.2);
greenled = 0;
wait(0.2);
} //end of else
} //end of while(1)
}
The following image shows the built circuit on a BAM210E.
