I am currently using an Arduino Uno in my R2-D2 (we were there at the Corporate office in August). I am looking to decrease the form factor. I will be running a very simple script, where I receive a serial command and then need to send out a serial command via another pin set. Below is an example of the script. I need to power with 5 V power, either through a terminal block or pin set (Not USB).
What would be a good, smaller Arduino board that would satisfy these requirements? I will need 4 of them.
const int rxPin = 2; // Define Rx pin
const int txPin = 3; // Define Tx pin
void setup() {
Serial.begin(9600); // Initialize serial communication at 9600 baud
Serial1.begin(9600); // Initialize Serial1 communication at 9600 baud
}
void loop() {
if (Serial.available() > 0) { // Check if data is available to read
char incomingChar = Serial.read(); // Read the incoming byte
// Send the corresponding second command based on the first command received
switch(incomingChar) {
case ‘0’:
Serial1.println(“0xA7,0x00”);
break;
case ‘1’:
Serial1.println(“0xA7,0x01”);
break;
case ‘2’:
Serial1.println(“0xA7,0x02”);
break;
case ‘3’:
Serial1.println(“0xA7,0x03”);
break;
case ‘4’:
Serial1.println(“0xA7,0x04”);
break;
case ‘5’:
Serial1.println(“0xA7,0x05”);
break;
case ‘6’:
Serial1.println(“0xA7,0x06”);
break;
case ‘7’:
Serial1.println(“0xA7,0x07”);
break;
case ‘8’:
Serial1.println(“0xA7,0x08”);
break;
case ‘9’:
Serial1.println(“0xA7,0x09”);
break;
case ‘A’:
Serial1.println(“0xA7,0x0A”);
break;
case ‘B’:
Serial1.println(“0xA7,0x0B”);
break;
case ‘C’:
Serial1.println(“0xA7,0x0C”);
break;
case ‘D’:
Serial1.println(“0xA7,0x0D”);
break;
case ‘E’:
Serial1.println(“0xA7,0x0E”);
break;
case ‘F’:
Serial1.println(“0xA7,0x0F”);
break;
default:
// Do nothing if an invalid command is received
break;
}
// Wait a short delay to avoid sending too rapidly
delay(100);
}
}
