The STM32 Nucleo-144 is a new series of development board by STMicroelectronics. It is the third announced series titled Nucleo. Each Nucleo-144 share the same pin map for each board and features a new connector named ST ZIO which is compatible with Arduino Uno Rev3 connector.
This new series takes his name from the number of pads exhibit by its different MCUs which are all a LQFP144 package. Indeed, the STM32 Nucleo is currently available in 5 configurations we will discuss later.
The STM32 Nucleo-144 comes in the classical transparent blister we have already seen continue reading...

In this article we will resume the topic started with in “Detecting obstacle with IR Sensor and Arduino”. More in details, we are going to use the IR sensor like an objects counter.
The counter application is often used continue reading...
BUZZ Click is a click board with a mikroBus form factor. It is substantially composed of a piezoelectric speaker having a resonant frequency at 3.8 kHz: this means we should expect best performances at this frequency. Let’s take a look to the principle of operation of DC and AC buzzer.
A piezoelectric loudspeaker also known as buzzer uses the inverse piezoelectric effect for generating sound. The piezoelectricity is a phenomena where mechanical stress produces the accumulation of electrical charges and then a voltage across the material. The inverse principle is true continue reading...
In this tutorial we are going to see how to connect a STLink v2 debugger to a Clicker 2 for STM32 enabling users to do debugging which could be very useful in development phases. A debugger is a computer program which is used to test and debug another program usually named Target.
In embedded things are slightly different since the code is executed on an external MCU and it is required an interface Computer-MCU. In this case the Target is the MCU and a debugger is composed by the ensemble of a hardware and a software tool. Nonetheless, when the majority of people is continue reading...

An object can be detected with an infrared system consisting of an infrared transmitter and a receiver. More in detail an IR transmitter, also known as IR LED, sends an infrared signal with a certain frequency compatible with an IR continue reading...
