Led Blinking: We will see blinking an normal dc led with arduino. Requiremnts: Arduino UNO Board – 1 No. LED – 1 No. Potentiometer – 1 No. Breadboard – 1 No. Below program is to blink an led with delay of 500msec of time: #define LED 10 void setup() { pinMode(LED,OUTPUT); } void…
Overview In today’s lesson, we will learn how to connect the keyboard to the Arduino. In embedded devices, one of the essential parts is the keyboard, which is used to interact with embedded devices, the keyboard is an input device used to give commands to other devices, from the calculator to the computer; keyboard input,…
Introduction Hi everyone, in this article we will see how to interface LED with 8051 using Keil IDE and proteus. Components Required LED Light Emitting Diode. These are the semiconductor light sources, Commonly used LEDs will have a cut-off voltage of 1.7V and current of 10mA. When an LED is applied with its required voltage…
Overview In this essay, we will study PIC Microcontroller push button interfacing. The GPIO (General Purpose input-output) pins are also provided by PIC, just like other microcontrollers. We can connect input-output devices to GPIO pins, such as LEDs, switches, adc power supplies, sensors, etc. Here, we’ll see how to operate an SPST (single pole, single…
Real-time clock A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in the personal computer, servers and embedded system, RTCs are present in almost any electronic device which needs to keep accurate time. Components Required: STM32F303CB/STM32 blue pill boards –…
Over view This project describes connecting a Slamtech RPLIDAR A1 directly to an Arduino using its in-built serial port. So no need to use the supplied USB interface. DESCRIPTION RPLiDAR A1M8 360 Degree Laser Range Finder – 6m (Radius Range) is a low-cost 360-degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. The system can perform a 360-degree scan within…
Overview Before building the robot, it is important to understand how the ultrasonic sensor works because this sensor will play an important role in obstacle detection. The basic principle behind the operation of an ultrasonic sensor is to record the time it takes for the sensor to transmit ultrasound and receive ultrasound after touching a…
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…
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 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…
