How to Use SPI Communication in STM32

In this STM32 SPI Example, we will use Arduino UNO as Slave and STM32F103C8 as Master with Two 16X2 LCD display attached to each other separately. Two Potentiometers are also connected with STM32 (PA0) and Arduino (A0) to determine the sending values (0 to 255) from master to slave and slave to master by varying the potentiometer.

Raspberry Pi Headless Setup Guide

Anyone who is interested in learning about computers and electronics will definitely love experimenting with a small and powerful platform “Raspberry Pi”. The only problem is that it doesn’t have a monitor and keyboard-mouse. This is actually isn’t a problem though, because there is a way to setup and work on the Pi without connecting it to a monitor and keyboard. It is called headless because it has no monitor and keyboard connected to it, so it is said to be running headlessly.

Interfacing Stepper Motor with ARM7-LPC2148

In today’s automation world stepper motor and servo motor are two most commonly used motors in embedded systems. Both are used in various automation machines like robotic arms, CNC machine, cameras etc. In this tutorial we will see how to interface Stepper Motor with ARM7-LPC2148 and how to control speed of it. If you are new to ARM7 then start by learning about ARM7-LPC2148 and its programming tools.

What is PWM

While ADC is used to read Analog signals by a digital device like microcontroller. A PWM can be considered as an exact opposite of it, PWM is used to produce Analog signals from a digital device like microcontroller. In this article we will learn about what is PWM, PWM signals and some parameters associated with it, so that we will be confident in using them in our designs.

Raspberry Pi GPS Interfacing

With the amount of power packed by the Raspberry Pi, it certainly will be quite awesome to build GPS based projects with the same cheap GPS modules and that is the focus of this post. Today in this project we will Interface GPS module with Raspberry Pi 3.

The goal of this project is to collect location data (longitude and latitude) via UART from a GPS module and display them on a 16×2 LCD, so if you are not familiar with the way the 16×2 LCD works with the Raspberry Pi, this is another great opportunity to learn.
