ATtiny85

The high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines 8KB ISP flash memory, 512B EEPROM, 512-Byte SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, USI, internal and external Interrupts, 4-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes, and debugWIRE for on-chip debugging. The device achieves a throughput of 20 MIPS at 20 MHz and operates between 2.7-5.5 volts. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.

BCD Watch (Binary to Decimal)

“What is BCD? The full form of BCD is binary coded decimal, as its name the binary digits is showing decimal value. It is a very simple representation of decimal numbers in different ways, so you can google BCD or …

Tiny I2C Routines for all AVR Microcontrollers

“This article describes a set of minimal I2C routines that allow just about any Microchip/Atmel AVR processor to connect to I2C peripherals. To demonstrate the routines I’ve designed a port scanner that displays the I2C address of a …

“Hey what’s up guys, this is the SHROOM PCB Badge that is themed after SHROOM from Super Mario. This wearable Badge is made completely from PCB I got from PCBWAY and is powered by an Attiny85 which is in …

Printing to a Serial LED Display

“This article describes a simple routine to allow you to use a low-cost eight-digit LED module to display formatted data from a microcontroller project The routine will work with almost any microcontroller; as a demonstration of the routine I’ve …

An Ultrasonic Range Finder Using Arduino

“An Ultrasonic Range Finder Using an SRF05 and an ATTiny85 An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle avoidance and distance measurement systems. The ultrasonic range finder measures …

ATtiny85 Snake Game

“When it comes to electronics, it’s the free-form designed ones that always catch my eye. Seeing how all the wires and components are connected just make it so fascinating and nice to look at. I wanted to try building …

ES Timer a Special Pomodoro Timer (Digispark ATtiny85)

“ES Timer powered by Digispark ATtiny85 is based on the Pomodoro technique, which can solve the problem of skipping the break phase between work phases. When you connect it to your system port (whether Windows, Linux or even macOS) it …

Introducing the ATtiny Device PCB - I2C slave devices

“Ever since I started playing with Arduinos and microcontrollers, I was always fascinated by one very specific chip. The Attiny85! I know, I know! It’s not the fastest microcontroller out there, nor it is the best but being so …

Tesla Battery Charge Reminder

“Arduino Nano or ATTiny85 sounds a buzzer if the Tesla is in the garage for more than 30 minutes without being plugged in. I built this project because my wife and I sometimes forget to plug in our Tesla after …

Neopixel Ring, Brass Circuit Sculpture Lamp

“I’m fond of circuit sculptures and often get inspired by others’ to build mine. This was the case for this one. I got inspired by this very nice LED cube I enjoyed the software side too, the various color …
