I have been working on input and output devices communication for weeks. For those weeks, I spent so many times on the ESP32 debugging and got nothing solved, which makes me be so despair about the foreseeable failure of my final project. This wildcard week, however, saved my final project. I joined the advanced embedded […]
1. Programming Board Blinking Code using Arduino environment CODE: I started with code code from Jaclyn Berry’s page : const int buttonPin = 7; const int ledPin = 2; int buttonState = 0; void setup() { pinMode(ledPin, OUTPUT); pinMode(buttonPin, INPUT); } void loop() { buttonState = digitalRead(buttonPin); if (buttonState == HIGH){ digitalWrite(ledPin,HIGH); } else{ digitalWrite(ledPin,LOW);

Introduction This page attempts to describe a procedure for installing a complete GCC-based toolchain on a modern Windows system. I’ve developed these instructions on my Windows 10 machine, but they should work for versions of Windows as far back as Windows 7. On older versions, you might want to use WinAVR. WinAVR used to be the preferred way to get

Introduction Many people where interested in microcontroller programming after the article which I wrote in 2002. However this first step to get the development environment up and running is the hardest. If something does not work then you have absolutely no clue where the fault is. Programmer cable wrong?? Circuit faulty? Installation incorrect? Parallel port

Step 1: Components and Where to Start I’ve started from the Arduino official site: https://www.arduino.cc/en/Main/Standalone where I’ve taken this picture, and where there is the list of all the components that you have to buy. Just the components that are showed in this picture. ( At the link, there are also others steps after this

Step 1: The Beginning Last week I decided to make a classic Arduino clone with an ATMEGA328P-PU. I seemed to be so easy and quick but a very bad surprise for me: I odered the cheaper ATMEGA328-PU (non P!!) that is to say: non pico power. The difference: this IC needs a bit more energy

Introduction The following diagram shows the system schematic of the Smart Plant Feeder. It contains the several major blocks: ATmega 323 is the CPU of the system. 5 VDC power supplier: an adaptor first transforms 110 VAC 60 Hz into 9 VDC; then a regulator keeps VCC stable at 5 VDC. A crystal of 32KHz

Board Design For part of my final project I want to make my own USB audio recording device. So I’ll try to develop all the necessary electronics this week. I have the analog circuitry I need from inputs week. But I don’t have a board ready to go with a USB-capable microcontroller (bit-banging will not suffice,
Atmel’s AVR series of controllers is one of the most popular with student and hobbyists. Any beginner in electronics or even professionals for that matter would appreciate an excellent development board. Development boards rid the user of the tedious tasks of prototyping and debugging necessary circuitry to run an IC. So check out the 10
