TinkerKit Power LED Overview The Power LED is an actuator. Five ultra-bright LEDs can be powered from an Arduino pin. Input: Arduino provides a maximum of 40 mA per pin, enough to light up the five LEDs using the DigitalWrite() and AnalogWrite() functions. Module description: This module features Five AWT801-S LEDs from Seoul Semi Conductor, the standard TinkerKit 3pin connector and a green LED that signals that the module is correctly powered and a yellow LED that is lit only when the LED is lit. A resistor limits the voltage from the Arduino, protecting the lights. This module is an ACTUATOR. The connector is an INPUT which must be connected to an OUTPUT connector on the TinkerKit Shield. Code Example /* based on Blink, Arduino's "Hello World!" Turns on an LED on for one second, then off for one second, repeatedly. The Tinkerkit Led Modules (T010110-7) is hooked up on O0 This example code is in the public domain. */ #define #define #define #define #define #define #define #define #define #define #define #define O0 O1 O2 O3 O4 O5 I0 I1 I2 I3 I4 I5 11 10 9 6 5 3 A0 A1 A2 A3 A4 A5 void setup() { // initialize the digital pin as an output. // Pin 13 has an LED connected on most Arduino boards: pinMode(O0, OUTPUT); } void loop() { digitalWrite(O0, HIGH); // set the LED on delay(1000); // wait for a second digitalWrite(O0, LOW); // set the LED off delay(1000); // wait for a second } Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Arduino: T010110
