In one of my Arduino projects I needed to show some numbers. Luckily, a 4 digit display lain around on my desk. Because it had a built-in driver which would save me from all the hassle with shift registers it looked like a perfect fit. I checked the chip the display was using and ...
The update mid function is probably the most complex portion of the code, although there is a lot of repetition for each of the four digits. This function looks at whether the middle segment of the digit needs to move. If it does, it then looks at whether either of the adjacent digits ...
In this how-to, we will be using the IRremote Library for the Arduino to test our remote, get the key codes for the keys we want to use, and finally testing it out with lighting up a seven segment LED display. You will need the following items: An Arduino (I use an Arduino Uno B...

In most of the applications, you need more outputs for interfacing LEDs or any other devices such as seven segments, 16 segments, LED flasher, etc. This IC is very handy to use. For increasing the output pins, you can interface this IC with different microcontrollers such asArduino Uno, PI...

Ambient light sensing and LCD display Using a Light Dependent Resistor (LDR) we sense the ambient lighting level. This is displayed on an LCD in terms of voltage and resistance. This demo is with TI MSP430F5529 LaunchPad but it can be with Arduino Uno as well. See the code for which ...
