In this article we look at a dot matrix display from keyestudio which is controlled by a HT16K33 The 8X8 dot matrix is composed of 64 light-emitting diodes, and each light-emitting diode is placed at the intersection of the row …

In this article we look at creating and displaying custom characters on an I2C 16×2 LCD to an Arduino, we chose an Arduino Uno but there is no reason this will not work with a different Arduino board. This can …

In this example we will write to the EEPROM which is on the micro controller of the Arduino The supported micro-controllers on the various Arduino and Genuino boards have different amounts of EEPROM: 1024 bytes on the ATmega328P, 512 bytes on …

In this example we will add bluetooth support to our Arduino, there are several low cost modules labelled either Hc-05 or HC-06. Here is a picture of one of them In this example we will connect one of these modules …

In previous posts we showed some examples for the 4067 16-Channel multiplexer – Arduino and 4067 LED example The HCF4051 device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The HCF4051 analog …

In this example we’ll be using the Microchip 24LC256 EEPROM, this chip when connected to an Arduino can increase the available memory space by 32kbytes. Here is a pinout of the IC The address pins, A0, A1, and A2, which …

In this example we connect an Arduino to a L9110 fan module. This is a commonly found, basic low cost module which consists of an L9110 chip and a small motor attached. You need 4 connections between the arduino and …

In a previous example, we did a basic copy of the Arduino capacitance shield but hey outputting to the Serial Monitor is a bit boring, so how about we pick an LCD or LCD shield to try this out with. …
