ToÂ makeÂ something with the Arduino, hook up some sensors (inputs) and actuators (outputs).
1 Hook up a knob sensor
A goodÂ way to get started with an Arduino is to hook up a 10K linear “potentiometer” (knob) to anÂ Arduino analog input.
- Hook the center wire from the knob, which is the â€œsignalâ€ wire (usually WHITE or YELLOW) to anÂ Analog In port, marked â€œA0â€.
- Hook the ground wire (usually BLACK) up to the pin marked â€œGNDâ€
- Hook the power wire (usually RED) up to the pin marked â€œ5Vâ€
2 Hook up a light sensor
For another kind of input sensor, hook up a light sensor by following the below diagram.
3 Hook up an LED output
To have an actuator (output), hook up an LED by following the below diagram. The resistor shown has RED, RED, BROWN, which indicates that the resistor has a value of 220. You can try any resistor from 100 ohms to 400 ohms.
4 Connect to Computer
Once all your connections are complete, use a USB cable to connect your Arduino to a computer. This will also provide power to the Arduino
Edison (or other WiFi system)
Identify the IP address of the device, and point your browser to it. E.g. http://10.0.1.6:9001
