Arduino Shift Register 74HC595 Library (For LED)
Of course 74HC595 can do more than just controlling dumb LEDs but LEDs is what commonly used to give example of how 74HC595 works and LEDs are used in decoration. Arduino shift register 74HC595 library makes prototyping with LED easy & fast. Furthermore, the user can add more features or examples to the library or it's fork to make it more useful to the new Arduino users. For this guide, the … [Read more...]
Arduino 3 LED and One Push Button
Previously we published some Arduino guides which use the millis function. Arduino 2 LED was a basic project, Arduino Flip-Flop Blinking LED With Push Button is somewhat advanced project. Others were One Push Button Multiple Functions supporting Single Press, Double Press, Long-Time Press, Arduino Blink LED Rate Depending On Push Button Press Duration etc. In this guide we will use 3 LEDs and one … [Read more...]
Sony Spresense : $65 Arduino IDE Compatible Development Board
Sony Spresense definitely a good board at $65. This development board from Sony is relatively new and sports expected better A/V hardware. Essentially it is a single board computer for IoT development. In other words it is an luxarious Arduino compatible board with ARM CPU. Of course it can run some kind of Linux on it. The board has integrated GPS, Hi-res audio output and multi mic inputs. The … [Read more...]
All the Sensors of Android Smartphone on Arduino With 1Sheeld+ Shield
You Can Use All the Sensors of Android Smartphone on Arduino With 1Sheeld+ Shield. You Can Literally Avoid Buying Few Hundred Dollar Worth Extra Shields. A standard mid-range smartphone of today, like Samsung J7 Max has lot of sensors and camera. 1Sheeld+ Shield uses Bluetooth BLE (the Bluetooth module we described before). 1Sheeld+ uses it's built-in Bluetooth BLE module to connect itself to iOS … [Read more...]
How To Save Sensor Data From Arduino To a Text File
There are very complex ways of saving sensor data from Arduino to a text file. Also there are easy program. There was time when Mac were run with user created programs. Roger Meier's Freeware site has such own created programs. Download the "CoolTerm" program. Extract it. Double click on the CoolTerm application to launch. Click on Connection, then go to Options and then in Serial Port Options … [Read more...]
Arduino MIDI Input & Virtual MIDI Piano Keyboard
We can use Arduino for processing MIDI input and use Virtual MIDI Piano Keyboard freeware on PC for testing purpose. MIDI controller is hardware or software which generates and transmits Musical Instrument Digital Interface (MIDI) data to electronic or digital MIDI-enabled device. We can directly connect the MIDI jack with Arduino with minimally complex wiring or use IC. We can program, create … [Read more...]
Arduino Bluetooth Remote Control Tutorial : Part I
Previously, we discussed how to use Wi-Fi module with Arduino and Arduino 4 channel relay. Making them working togather with smartphone not that easy. Bluetooth is Easier Than Wi-Fi From Programming Aspect To Build Wireless Electrical Switch. Here is Part I of The Arduino Bluetooth Remote Control Tutorial. There are various bluetooth modules for Arduino including modules supporting BLE. A … [Read more...]
Arduino 3 Leg Bicolor LED Wiring and Code to Blink/Fade
Bicolor LEDs are cheap and quite popular as indicators of various things. 3 leg Here is Arduino 3 leg bicolor LED wiring and code to blink or fade. LEDs have color specific resistor values. A bicolor LED is practically two LEDs with one common anode or cathode. Some have common positive terminal (anode) and some have common negative terminal (cathode). When different voltage is applied to … [Read more...]
Arduino 4 Channel Relay Module : Description of Connections
This guide is not intended for the children as it involves household supply electricity. Household supply AC is overpowered enough to kill a human. We believe that controlling AC powered things like a bulb with Arduino often scary to many of the sane, careful hobbyists. However, with proper precautions they can keep you safe. Here is Description of Connections of Arduino 4 Channel Relay Module. … [Read more...]
