Save some arduino pins when driving a 4 digits 7 segments display

I built a simple clock using a 4 digits 7 segments LCD display. I display one digit at a time, switching on and off very quicky and cycling through digits. Everything is ok, but I used 8 + 4 = 12 arduino pins. I need 2 more pins for other features…

Can the Arduino Uno become an AVR programmer and use the ICSP header to program the target board

The Arduino Uno has an ICSP header that I imagine is for programming the board using a separate ICSP programmer. That is, its ICSP header turn the board into a target. Can one use that same ICSP to program other boards, turning the Arduino Uno…

Why use .h files with .cpp?

At school, our teacher always taught us to use .hpp (C++ Header files) with our .cpp (C++ files). But Arduino seems to use .h files (with .cpp links?). When someone is programming in C (without C++ compiler) they have the chance to get linked to a…

Do gyroscopes purposefully show erroneous data?

I tested an MPU-6050 (GY-521) using an Arduino Nano. I used the I2CDevLib and opened the MPU6050_DMP6.ino with the Arduino IDE. I opened the MPUTeapot.pde Processing-file with Processing. A few changes was necessary to make it work: MPU6050…

millis() function with a button press

I am trying to use the millis() function to turn on a pin for a specified interval then turn off and turn on a second pin. It is intended to power a relay and offer a visual cue to when the cycle is over. Several of these need to eventually be…

Can I damage an arduino by setting pins high with no load

I have an Arduino project that has 15 different output pins set. Some are currently attached to devices and others are not. Will testing my program cause a problem / damage if it sets pints to HIGH that do not have anything connected to them?

How to add the Wiring S board to Arduino IDE v.1.6.2?

My Arduino Uno is running out of memory to support my script (yes, I've tried several ways of optimize it already: PROGMEM, EEPROM, no Strings, and so on), so I would like to upload my script to my Wiring S board. However, instead of "porting" all…

How to calculate phase shift between two square waveforms with Arduino DUE

I have two square wave signals with the same frequency. I want to measure the phase shift between these two signals. There will be a small phase difference between two signals. (0-90 degree) and the frequency will vary in the range 100mHz - 50kHz. I…
