Interfacing Ultrasonic sensor with Arduino UNO HC-SR04 As show in the figure HC-SR04 is an ultrasonic sensor. It is an 4pin module consists of Vcc, Trig, Echo and GND. Module had a transmitter and receiver which transmits and receive the ultrasonic wave signal. Pins Explanation: VCC – +5v dc TRIG – To activate sensor we…
Overview In this tutorial, we will learn how to program the ESP8266 OTA using the Arduino IDE. We will learn about an interesting feature of the ESP8266 NodeMCU module that will allow us to perform OTA updates over the air. This means that the ESP8266 module, like other Wi-Fi-enabled microcontrollers, supports over-the-air updating of firmware…
Hi everyone, this blog is to send a data to ThingSpeak server using the STM32 microcontroller. What are AT commands? AT commands are commands which are used to control the modems where AT stands for Attention. These commands were derived from Hayes commands which were used by the Hayes smart modems. Every wireless, as well as the…
Overview In this project, we’ll learn how to start a vehicle using a fingerprint sensor and how to prevent vehicle theft. We use a fingerprint-based bike start mechanism in this system to address the problem that many people have of leaving their keys somewhere after leaving their home but forgetting where they went until they…
Overview In TMS320 PWM Tutorial, you are going to learn about what PWM is and how you can get the PWM output from the Analog pins of tms320. First, we will generate a PWM signal and then we will control it manually by adding the potentiometer. What is PWM This project involves a combination of…
About 7 segment display: Seven segment displays are the output display device that provides a way to display information in the form of an image or text or decimal numbers. It consists of seven segments of light-emitting diodes (LED s) which are assembled like numerical 8. Since seven segment displays can not form an alphabet…
