Curiosity Development Kit Board
Satisfy Your Curiosity Your next embedded design idea has a new home. Curiosity is a cost-effective, fully integrated 8-bit development platform targeted at first-time users, Makers, and those seeking a feature-rich rapid prototyping board. Designed from the ground-up to take full advantage of Microchip’s MPLAB X development environment, Curiosity includes an integrated programmer/debugger, and requires […]
Keypad 4×5 for microcontrollers v. 1.1 using PIC16F877
What’s this? The circuit here described is a simple 4×5 keypad that can be used in particular with the PIC 16F877 microcontroller, for which it has been designed considering a supply of 5V, 16F877 I/O pins leakage current, the voltage level recognized as a high or low state while in TTL or ST mode, etc.. […]
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?
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 […]
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 letβs first discuss […]
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
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. […]

I2C Sonar Ultrasonic Range Finder In many embedded systems design, it becomes necessary to have the capability of discerning […]
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, […]
