Wire servo on A2, Pot on Pin A1.
When you run the sketch below you should be able to turn the 10k potentiometer to control the servo.
#include #include <Servo.h> Servo myservo; // create servo object to control a servo int senPin = A1; int servoPin = A2; int senVal = 0; void setup() { Serial.begin(9600); myservo.attach(servoPin); // attaches the servo on pin 9 to the servo object } void loop() { senVal = analogRead(senPin); Serial.print("senVal: "); Serial.println(senVal, DEC); senVal = map(senVal, 10, 104, 10, 170); myservo.write(senVal); delay(15); }
Test UDP + WiFi Connection with ARWINC1500
On you Mac
Download Packet Sender for your Mac
Find out your IP address by Option + Click the WIFI icon on the upper status bar
Download and Install this Library
https://github.com/adafruit/Adafruit_WINC1500
Run the Example > Adafruit_WINC1500 > WiFiUdpSendReceiveString >
just to make sure that your Wifi is working by changing the following 2 lines
char ssid[] = “SkyNet”; // your network SSID (name)
char pass[] = “password”; // your network password
Serial Monitor
After uploading the sketch, it should say something like this in Serial
Connected to wifi
SSID: SkyNet
IP Address: 192.168.13.4
signal strength (RSSI):-30 dBm
Starting connection to server…

# Run the WiFiUdpSendReceiveString Example
# Open Serial Monitor
# Get the IP address from Serial Monitor
# Paste the IP Address in Address field in Packet Sender
# Use port 2390
# In Packet Send, Change TCP to UDP
# Type Some ASCII message then check HEX field to cover the string
# Click Send
You should see the message in Serial Monitor

iPhone UDP
# Download UDP Test Tool https://itunes.apple.com/us/app/udp-test-tool/id469617393?mt=8
# Type IP address from your Serial Monitor into the “Sending data to:” field
# Use port 2390
# Type some message then click Send
TIP: Some router allows you to assign internal IP address. You can also do port mapping or DDNS, that way you are not limited to only internal network.

ATWINC1500 sends sensor data to Computer via UDP – DEMO
void messageSender()
This function sends out the sensor data via UDP
Udp.beginPacket(“192.168.13.3”, 55056);
Sends the sensor to certain IP address and port.
I used Packet Sender on my Mac to get UDP data
