TinkerKit Mosfet Module Overview This module switches a high current load using a high power transistor. Unlike a mechanical relay, this is capable of high speed switching for use with PWM. Input: This module lets you control devices operating at a maximun of 24VDC with an Arduino pin. To wire the module, connect the power supply for your device (max 24 V) to the V+ and GND terminals. Connect the device to M+ and M-. Be aware of your circuit's polarity, you could damage your components if it is not wired correctly. Module Description: This module features an IRF520 power MOSFET transistor, a kick-back diode, a standard TinkerKit 3pin connector,a signal amplifier, a green LED that signals that the module is correctly powered and one yellow LED whose brightness depends on the input signal received by the module. This module is a ACTUATOR. The connector is an INPUT that must be connected to an OUTPUT on the TinkerKit Shield. Code Example /* based on Blink, Arduino's "Hello World!" Turns on a transistor on for one second, then off for one second, repeatedly. The MOSFET is on O1 modified 15 jan 2011 by Scott Fitzgerald 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. pinMode(O1, OUTPUT); } void loop() { digitalWrite(O1, HIGH); // turn the MOSFET on delay(1000); // wait for a second digitalWrite(O1, LOW); // turn the transistor off delay(1000); // wait for a second } Mouser Electronics Authorized Distributor Click to View Pricing, Inventory, Delivery & Lifecycle Information: Arduino: A000004
