Many folks starting out in microcontrollers do not know what interrupts are, or are intimidated by them. Today I hope to shed some light on this easy to use, and useful function. There are two ways to detect if an
This is the fourth tutorial in our 37 in 1 Sensor Kit series. We have addressed this module and it’s family in several previous posts. It’s a low end temperature and humidity sensor accurate enough for residential weather and environmental
This is the third tutorial in our 37 in 1 Sensor Kit series. Normal volume controls and potentiometers have stops at each end of the scale. A rotary encoder is a bit different. There are no stops, it’s continuous 360
This second sensor project uses the IR Fire Sensor. It has two outputs, 1 digital, 1 analog. I’m using the digital output (sensitivity set with onboard trimmer pot) to set the Pin 13 LED, to show flicker. I’m dumping the
We recently received a kit of sensors, and have started documenting how to use them. The sensor we are working with today is a joystick. This is a 2-axis unit with a push button on the shaft. There are two
This is the beginning of a multi part series on interfacing a PC keyboard to an Arduino. PS/2 keyboards are ideal, but many USB keyboards provide a PS/2 compatible scan code, so we will address support for those as well.
