In this example we will connect a 7 segment display to an Arduino Schematic Code [c] const int  A = 4; const int  B = 5; const int  C = 6; const int  D = 7; const int  E = …

In this example we connect an LDR to analog 0 and depending on the value read in we then vary the brightness of an LED connected to Pin 9 using PWM. The input read from the analog pins will be …

This code snippet will get the button value and display the value on the 7 Segment LED and the LEDs Code [c] #include <TM1638.h> // define a module on data pin 8, clock pin 9 and strobe pin 10 TM1638 …

When I was browsing various web sites to see what electronic components to buy one day I noticed some interesting little kits comprising of switches, LEDs and a couple of 4 digit seven segment displays saw I decided to purchase …

Taking our hello world I2C OLED example a bit further, this is our next creation. We connect a DS18B20 temperature sensor and display the temperature on the display Coding You need to download and install various libraries and copy them …

Just recently I spotted various I2C OLED displays on sale at reasonable prices and fancied trying to connect these up one of my Arduino’s. Being relatively small size, requiring only 2 connections SDA and SCL from the Arduino but still …
