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.…

Its a fairly simple process to connect your Arduino to your PC and write an appilcation to interact with your hardware. You will need the usual Arduino hardware, IDE and in this case an LED connected to the board. For…
