Building a High-Precision Radio Frequency Beacon Finder

Radio Projects / Ibrar Ayyub

This project designed and built a radio frequency (RF) receiver unit that can detect RF signals transmitted by beacons operating at 433MHz and provide information to help the user locate the beacons. The motivation came from wanting to track small attachable beacons that could be placed on personal items to locate them if lost or

MicroPython IoT Rover Based on WEMOS D1 (ESP-8266EX)

Blog / Muhammad Bilal

** Update: I posted a new video for v2 with a lance ** I host Robotics workshops for young kids and I’m always looking for economical platforms to build intriguing projects. While Arduino clones are cheap, it uses the C/C++ language that kids are not familiar with. Also, it doesn’t have a built-in WiFi which is a

Debugging AVR Code in Linux With Simavr

LED Projects / Muhammad Bilal

I recently started programming AVR chips, namely the ATTiny85. They can be programmed using C, compilers are readily available in Ubuntu, and you can do a LOT with them – just search for avr on this site! Anyway, I was having some trouble with my project today – the LED wouldn’t flash! I couldn’t figure

ISP Programmer for ATmega32 Microcontroller

AVR ATmega Compilers / Ibrar Ayyub

So far I’ve discussed about the micro controller basics and the compiler software. I’ve yet not written anything about programming. ATmega32 series micro controllers support 3 types of programming Parallel Programming ISP Programming or serial Programming Programming via JTAG Here ISP stands for In System Programmer. To burn a micro controller just

Working with External Interrupts in AVR micro controller

Microcontroller / Ibrar Ayyub

Introduction to Interrupts Although micro controllers can accept inputs from Digital I/O Ports,interrupts are preferred for accepting inputs generated by external events. This is mainly because of the less attention required for an interrupt based program. An Interrupt Event directs the flow of program execution to a totally independent piece of code, known as “Interrupt
