Introduction ProxiMIDI is a MIDI code generator, that takes its inputs from a user using Atmel’s Capacitive touch and Proximity technology. It can generate sound signals for 4 notes of 3 instruments and vary the tempo, volume and sound depending upon the proximity inputs. The signals generated from ProxiMIDI can be connected to any MIDI […]

What We Did We created an autonomous robot that explores the world in linear trajectories while avoiding obstacle using IR range-finding. The robot is a Venom RC car altered to be controlled by an Arduino Uno programmed in AVR Assembly (a very low-level programming language specific to the type of hardware used). The Arduino communicates

Introduction Printed circuit boards (PCBs) are the backbone of every electronic gizmo out there. They’re not flashy like those microprocessors, or abundant like resistors, but they’re essential to making all components in a circuit connect together just right. We LOVE designing PCBs here at SparkFun. It’s a love that we want to spread. It’s a

1 Starting Forth Forth[3] is a flexible, stack-based programming language that is ideal for embedded use. It has an amazing power to weight ratio; it can do a lot with limited resources. Forth zealots take this as one of many signs that Forth is the One-True-Language. I disagree; modern desktops and laptops are so powerful that

This project was done in order to experiment with the Automotakit breadboard board which is based on the ATMEGA256A3U chip. The use of a DAC, ADC , low pass filter, PWM, basic I/O, current control, clock setup, and interrupts on an Atmega chip are some of the topics explored here. In order to experiment around, the datasheet

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

Code explanation for MASTER Controller: Step 1: Initialization of master. Initialization of MASTER means to set the TWI clock frequency (SCL). It is done by setting bit rate in TWBR and pre scaler bits in TWSR. Fig. 2: Equation Of
