Frequency Counter by PIC16F628 schematic

Frequency Counter by PIC16F628

In this project we are building a basic and low cost frequency counter circuit . It can measure from 16Hz to 100Hz signals with a maximum amplitude of 15V. The sensitivity is high, the resolution is 0.01Hz. The input signal can be a sine, a square or a triangle waveform. The counter can be used […]

Frequency Meter Using Microcontroller

This tutorial simply states how to calculate frequency of a pulse source using a microcontroller. Story This tutorial simply states how to calculate frequency of a pulse source using a microcontroller. A high voltage level of pulse source is 3.3 V and low is 0V. I have used STM32L476, Tiva launchpad, 16×2 alphanumeric LCD some […]

WHAT IS A PIC MICROCONTROLLER WHAT CAN IT DO

WHAT IS A PIC MICROCONTROLLER? WHAT CAN IT DO?

PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost […]

Program SMD Microcontrollers Without Soldering e1680937191532

Programming SMD Microcontrollers Without Soldering

I failed in this wirelessly programming method, But I want to try more methods because finally, we are engineers. Story I tried to put my effort to program a single smd Arduino chip without soldering. But I get failed, and now I am here to explain the concept I am thinking. But let’s first discuss […]

Infrared Remote Controlled RC Steerable Vibrobot Created by Naghi Sotoudeh schematic

Infrared Remote Controlled (RC) Steerable Vibrobot Created by Naghi Sotoudeh

Vibrobots (and bristlebots) are simple robots that use a tiny pager / cellphone vibrator motor (with an eccentric weight) to randomly bounce around — they are the subject of many Maker / DIY projects as well as some well-known commercial toys (such as the $7.00 Hexbug Nano).Β  Naghi Sotoudeh, a Hizook reader from Iran, contacted […]

Remotely Controlled Microcontroller From a Browser e1680933887671

Remotely Controlled Microcontroller From a Browser

Interface with a microcontroller from a web browser, using HTTPS and a simple Python server. Story I love microcontrollers. I also love controlling hardware remotely, say, from another room of my house. The idea of being able to do this through a browser, like from my laptop or phone, rather than from an ssh console. […]

Build a DIY Smart Watch Using Microcontroller e1680927157715

Build a DIY Smart Watch Using Microcontroller

Introduction Wearables (Smart Watch) are becoming increasingly more prevalent in today’s markets; however cost continues to limit the demand for such devices. My project aimed at producing a smartwatch with comparable functionalities to those available today. While running a total cost of less than $100. The watch is outfitted with a 1.7 inch touch screen, […]
