Lesson 16--Microduino Digital Tube Experiment 3 - Display Infrared Remote Control Button Value

Language:	English  • 中文

Objective This lesson will show you how to use digital tube on Microduino and use the infrared remote control to control the number display. Equipment Microduino-Core Microduino-FT232R Other equipment: Breadboard Jumper one box Breadboard one piece USB Data cable one The infrared receiver one Remote control one 220Ω resistor one Schematic Program Download program: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Advanced/MicroduinoDigitalTubeExperiments3 #include <IRremote.h> #include <SevSeg.h> SevSeg sevseg; int RECV_PIN = 2;//Define infrared receive pin 2 IRrecv irrecv(RECV_PIN); decode_results results; int t; int action; int deckey(unsigned long t) { switch(t){ case 0xFD08F7://Button 1 encoding return 1; break; case 0xFD8877://Button 2 encoding return 2; break; case 0xFD48B7://Button 3 encoding return 3; break; case 0xFD28D7://Button 4 encoding return 4; break; case 0xFDA857://Button 5 encoding return 5; break; case 0xFD6897://Button 6 encoding return 6; break; case 0xFD18E7://Button 7 encoding return 7; break; case 0xFD9867://Button 8 encoding return 8; break; case 0xFD58A7://Button 9 encoding return 9; break; default: return 0; break; } } void setup() { //Define used pin sevseg.Begin(1,2,3,4,5,6,7,8,9,10,11,12,13); irrecv.enableIRIn(); // Initrize the infrared receive //sevseg.PrintOutput(); //sevseg.NewNum(0, 4); } void loop() { //Enable the output function sevseg.PrintOutput(); if (irrecv.decode(&results)) { Serial.println(results.value, HEX);//In hexadecimal output the receive code in a new line action=deckey(results.value); Serial.println(action); Serial.println();//Add a blank line and easy to observe the result sevseg.NewNum(action, 4); //Digital tube function outputs number, the second parameter is the positon of decimal point. Because it is 4, so won't dispaly decimal point irrecv.resume(); // Receive next value } } Debug Using the SevSeg library Library link: [1] Step 1: Copy code to IDE Step 2: Set up circuit, as follows: Step 3: Run program Result Press the 1~9 button on remote control, the digital tube will display corresponding number. The infrared received encoding are in source code, but different remote control may have different encoding, need to change code. Video
