Things used in this project Hardware components: OLED 128×64 SPI-capable Available on Aliexpress or eBay for $4 to $20 × 1 For standard Arduino platforms, use the unmodified Adafruit libs × 1 Story I like cheap electronics for playing. Cheap is good for budget conscious hobbyists and China is delivering lots of toys for playing […]

I have been tinkering with Word Clocks for years. There is only one thing I like more than making word clocks… it’s designing them so that they are easy to put together. This tutorial will go through my latest version (5!!!!!). By the end of it you will have a clock with: User selectable colours

Story This would be the continuation of my previous project Programming ATtiny85 with Arduino Uno. Now with cheaper ATtiny85 in place I was looking for cheaper ways to transmit the sensor data. Which brought me to nRF24L01+ a cheap, low power RF transceiver. This seemed to be the better solution for me. But there was

Story I am working on a project which requires reading multiple sensor data on different locations. These require only few PWM pins so using multiple Arduino Uno would be expensive and unnecessary. So I decided to use ATtiny85 microcontroller in place of Arduino Uno development boards.ATtiny85 is a cheap and powerful alternate when u don’t

Story An Arduino consists of many components like: a linear regulator, USB to Serial microcontroller, debug LED, power LED, reset button, RX & TX LED, crystal oscillator, etc. But a minimal circuit can have just the brain of the Arduino UNO, that is, an ATmega328p microcontroller (Reducing Arduino Power Consumption). You can assume this one

Story When it comes to portable electronics, one of the most important features is how to maximize the battery life. The ATmega328P, used on popular boards like the SparkFun RedBoard, Arduino Uno, and Pro Mini are actually quite power hungry. The RedBoard and Arduino Uno, draw around 15mA minimum, which doesn’t sound like much but

Story Did you see this 8MHz no-crystal Arduino? Arduino on Internal Oscillator Crystal as Clock Source by Naman Chauhan is a great project if you can live with 8MHz using the internal RC oscillator of the Atmega328P chip. I really like Naman’s project; I did my own version of the 8MHz Arduino many years ago

Story Hello everybody, This is my first project using ATtiny85 microcontroller and also including a Real Time Clock (RTC) working with it. The use of ATtiny85 is a very interesting way to shrink your Arduino projects in a final tiny version. The Three-Modes Digital Clock includes a version with common decimal clock and also with

Story What is a Bootloader? Microcontrollers require a programmer to install firmware on them. A programmer is a device, that when combined with software, loads firmware to the microcontroller. There are many programmers available. I won’t go into to detail about them, but I will say that if you intend to do more than just
