Overview This is a series of robots that uses three wheels to drive over almost any terrain. Works on any interior and exterior surface. This robot uses Android technology. This can be moved back and forth using 60RPM geared motors. Also, this robot can make sharp turns to the left and right. This project uses…
In this tutorial, I want to show you how to flash the code using a mobile phone application. Nearly every embedded system needs the ability to have its firmware updated in the field to add new features or fix bugs. However, firmware field updates can be challenging as a developer must either program their bootloader…
GSM Network time synchronization for RTC using AT+CLTS command Since I started designing the VALTRACK GPS trackers, I have always had trouble maintaining the tracking device’s correct time because once I removed the battery, the PIC RTC lost its synchronization. I didn’t have the space or luxury to maintain a separate backup battery for the…
A/D Converters (ADC) In this tutorial, I will show you how to use ADC in STM32F303CBT6/STM32F103C8T6 to measure the Input Analog Voltages. Analog to Digital Converters (ADC) translate analog electrical signals for data processing purposes. With products matching performance, power, cost, and size needs, Analog Devices offers the industry’s largest A/D converter portfolio. As the…
Overview We will learn everything we need to know about using an Arduino to operate stepper motors in this lesson. We’ll go over how to use an M415B and a TMC2208 stepper driver to control a NEMA17 stepper motor. Numerous devices like 3D printers, CNC machines, robots, automation machines, and others that require position control use…
Introduction: Hi, in this article we will see how to send SMS with SIM800 GSM module using blue pill microcontroller in Keil IDE. SIM800 is a quad-band module 850/900/1800/1900MHz and this module support USART Communication. Requirements: Blue pill – 1 ST-Link Debugger – 1 FTDI – 1 Breadboard – 1 Jumper wires Schematic Diagram: GSM…
Introduction The ADC module is a successive approximation (SAR) style ADC with a selectable resolution of either 16 bits or 12 bits. The ADC is composed of a core and a wrapper. The core is composed of the analogue circuits which include the channel select MUX, the sample-and-hold (S/H) circuit, the successive approximation circuits, voltage…
Introduction: In this tutorial, I am going to explain about sending sensor values to the thing speak server. ThingSpeak is an open-source server, so users just need to sign up with your email id. After sign up creates a new channel to get an API key, this key is unique for every channel. By using…
Overview PWM (Pulse Width Modulation) is a method of controlling the average voltage. It is a current of voltage pulses that reduces the electrical power supplied by the electrical signal. The effective voltage is monitored by displaying individual pulses in the PWM signal voltage pulse current. A PWM signal consists of two main components that…
Overview Agriculture continues to play an important role in the Indian economy. The agricultural sector is changing the socio-economic environments of the population due to liberalization and globalization. The irrigation system in India has been given high priority in economic development. Many new concepts are being developed to allow agricultural automation to flourish and realize…
