ijoijo part 2

In previous post, ()prototyping went well. in order to move it to the “real life”, I’ve got clone of , simply because it is just cheaper, then to build my own Atmega 328 board. Everything will be powered by 3*1,5v AA batteries, in handy battery pack, that has convenient power switch built in. So after […]

Prolific PL2303 Windows 8

Somebody screwed the pooch on this one, even though prolific says that old chip will not work with w8 it does, but with old,old,old drivers… PL2303_Prolific_Vista_332102 step 1 – uninstall (and delete) current driver step 2 – install what’s in the file step 3 – if it still not working, go to driver, update it […]

ijoijo

That’s my little project im building for my little son, lights and siren for his little tikes car. Little visualisation of the idea. Developed in fritzing. (http://fritzing.org) Video of prototype And THE code. const int buttonA = 10; // the number of the pushbutton pin const int buttonB = 12; // the number of the […]

ServoTester

Quick adn dirty servo tester for RC purposes. Code is modified debounce found at Arduino.cc I’ve used my 20×4 I2C LCD, though there is no suitable part in Fritzing, thus used regular 20×2. #include <Wire.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0×20,16,2); // set the LCD address to 0×20 for a 16 chars and 2 line display #include […]

Mega2560 as ISP for UNO

Title says everything, but it still sounds like a Morse Code, I’ve used my Arduino Mega 2560 to program (through my Arduino UNO) an Atmel Microcontroller, Atmega328p-pu picture says everything. as above wiring is: MEGA – 50 -> UNO – 12 MEGA – 51 -> UNO – 11 MEGA – 52 -> UNO – 13 […]

74HC595

I’ve got around to practical application of Atmega328P and 74HC595, that will be a part of the project I’m currently working on. this time 74HC595 and 8 (so far… I’m shooting for 15) LED’s. Short video material: Image developed using Fritzing. Code based on Adafruit’s arduino lessons. int latchPin = 5; int clockPin = 6; […]

DHT11 and BT updated

Recently I’ve posted and modified a bit code in order to be easily interpreted by application I’ve compiled for Android. I’ve used appinventor in order to develop it. source package for appinventor is there –> DHT11Bluetooth_v101 Android application reads string that Bluetooth outputs and dissecting it, string format is T:xxxH:xxx where “xxx” are the values. […]

LCD in I2C

Little side project was to reduce amount of wires on my LCD and I’ve succeded. #include <Wire.h> #include <LiquidCrystal_I2C.h> #define lcdAddr 0×20 // set the address of the I2C device the LCD is connected to // create an lcd instance with correct constructor for how the lcd is wired to the I2C chip LiquidCrystal_I2C lcd(0×20, […]

DHT11 and Bluetooth

I’ve received finally a tiny Bluetooth, so I’ve added temperature sensor, and Nokia’s LCD and whipped up thermometer that sends temp through BT. Next step, add ethernet shield to all that. Image developed using Fritzing. #include <Adafruit_GFX.h> #include <Adafruit_PCD8544.h> #include <dht11.h> dht11 DHT11; #define DHT11PIN 2 // pin 7 – Serial clock out (SCLK) // […]
