Overview An automated counter system is an efficient solution for counting the number of people entering or leaving a bus. Highlight people and passengers counters are compact and autonomous devices based on non-contact stereoscopic vision technology. They have been designed for passengers counting above the doorways of buses and rolling stocks and counting people as…
Overview A deadband or deadband (also known as a dead zone or a neutral zone) is a band of input values in the domain of a transfer function in a control system or signal processing system where the output is zero (the output is ‘dead’ – no action occurs). Deadband regions can be used in control systems such as servo amplifiers to prevent oscillation or repeated activation-deactivation cycles (called ‘hunting’ in proportional control systems)….
Overview This tutorial will help you connect App Inventor with a temperature sensor on an Arduino controller. Block Diagram: Pins connection: About Bluetooth module HC-05: HC-05 is a Bluetooth module which is designed for wireless communication. It uses serial communication to communicate with devices. HC-05 has a red LED which indicates connection status, whether the Bluetooth…
Overview Inventor of the MIT APP Arduino Bluetooth application. I have used Bluetooth mobile phone applications to monitor and control various types of sensors and electrical loads. I developed all my previous apps in Android Studio. A few months ago I uploaded articles on how to develop a custom Android app to control electrical loads…
Overview This project is about creating an automatic fan control system that automatically turns the fan on and off depending on the room temperature. I used an Arduino UNO microcontroller here, you can also use a MINI, but there will be some problems with power regulation, so choose UNO 🙂 The temperature sensor here is…
Overview In this tutorial, we are going to make a digital clock with Arduino UNO, an RTC module and an OLED display. Hardware & Software Needed Arduino IDE Arduino UNO DS3231 SSD1306 128×32 OLED Screen Project circuit: DS3231 RTC Description DS3231 RTC is a precise real-time clock module with 32Kbit EEPROM and a built-in 10bit…
Overview In this tutorial, we will look at Arduino interrupts. Interrupts are useful in many cases where a process simply wants to continue its main function, and other devices (timers or external events) come to its attention if necessary. Specifications: ATMEGA2560 Microcontroller Operating Voltage: 5V Input Voltage (recommended): 7-12V Input Voltage (limits): 6-20V Digital I/O Pins: 54 (of…
Overview In this guide, we will learn how to use the TM1637 4-digit 7-segment LED display with the TMS320. These screens are cheaper and more suitable for displaying sensor data, time, stopwatch, random numbers, etc. They are similar to other 4-digit 7-segment displays, but have a built-in TM1637 LED driver IC. This eliminates additional wiring…
Overview This is a simple project on the seven segment display interface with tms320f28335. The tutorial presents a simple example of printing numeric numbers on a seven-segment display. The tutorial task is to print numbers from 0 to 9 on a single seven-segment display. There are two types of seven-segment displays, Common Anode and Common…
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…
