ATtiny keychain game console

Posted on by Leave a comment

This tiny keychain game console is pretty neat and is based on ATtiny85 and and a SSD1306-driven OLED screen. The author has also shared the code for the UFO Escape game for this console. I finally had some free time to make something fun and decided to write a new game for the Attiny85 ssd1306 keychain.  I reused the sleep, display and interrupts code from the “Breakout” game I created a while ago. This time I wanted a more addictive game. The game had to be playable using just the two buttons. I thought a racing game might be a good

New product: ASK RF transmitter and receiver kit

Posted on by Leave a comment

Today, we have added a new product to our Tindie store. It is a complete set of ASK RF transmitter and receiver modules for enabling wireless data transfer between two Arduinos. The kit consists of high quality ASK transmitter and receiver modules (433MHz carrier) along with matching copper spring antennas. There are tons of other cheap ASK modules available in the market. Most of them do not come with antennas and the user has to cut out and install a right size wire antenna for reliable operation. Our kit includes a complete solution with copper spring antennas. Following features makes

Wireless communication between two Arduinos using inexpensive RF modules

Posted on by 8 comments

This article explores an easy wireless communication setup between two Arduinos using low-cost ASK RF transmitter and receiver modules that are readily available in the market. They are found in different shapes, but functionally they are all same. Both Tx and Rx modules contain a single data line for input and output and support a low-speed Amplitude Shift Keying modulation for data communication. You can get them with 315MHz or 433MHz carrier frequency. In this tutorial, I am using a 433MHz Tx/Rx pair with two Arduino boards to illustrate how to construct a low-range wireless temperature and humidity monitor.

ESP8266 based Weather Station with a beautiful look

Posted on by Leave a comment

Dennisv15‘s Weather Station is WiFi enabled using ESP8266 and uses a 2.4″ OLED to display the weather data. It has got one of the most beautiful enclosure made of Acryllic sheet laser-cut in the shape of the Sun and cloud. The shapes are illuminated with different colors based on the weather forecast using RGB LEDs. The firmware is based on Daniel Eichhorn’s popular design of an ESP8266 based weather station that includes measurement of the indoor temperature and humidity using DHT22 and retrieving local forecast data from Wunderground.
