This is the code I use for the clock. Feel free to change it in each manner your want. ATTENTION: Dont use the POV Clock_old. I use it for backup purpose only. It wont work! The file POV Clock_new and POV_Clock_new_SSD1306 are working well and are fully tested. But i dont take any responability if something dont work like you want. For example: the optocoupler is tricky. Maybe you need to adjust t...
Compact speedometer with OLED display and temperature measurement.
It features an ATtiny85 uC with USB programming and battery charging and protection circuitry. I will be using it to measure the speed of my bicycle and determine the temperature around me on my rides.
The project consists of 2 pcbs: the sensor that will be mounted on the wheel of my bike and the actual speedometer.
Display-Module created and developed for Eurorack-Synth-Modules.
Digit height: 5.03mm !
Module size (w x h): 20.7mm x 22.86mm
For following controllers:
Example code using Attiny84:
Programmable Signal Generator
This project describes a simple digital signal generator capable of generating a square wave from 1kHz to 68MHz with an accuracy of 1.1%. You enter the frequency on a numeric keypad, and the frequency is displayed on an I2C 128x32 OLED display.
Used components: ATtiny85, OpAmp INA331/LTC6904, OLED display (connector JP1/JP3).
Breakout board for the Electronic Assembly eDIP240-7 display for control via an I²C interface.
- I²C addresses can be set via a dip switch.
- I²C pull-up resistors integrated.
- With reset button to avoid annoying plugging in and unplugging.
Use pin headers (2x 1x20) to be able to detach the display from the board
This small device that indicates an input byte in hexadecimal on two 7 segments led displays. It can be inserted into a breadboard or a connector. It displays in hexadecimal the byte placed on its 8 binary inputs.
It is powered in 5 volts and consumes only 10 to 15 milliamperes because thanks to multiplexing, at most only one of the 14 segments is switched on at a time.
It can replace 2 TIL...
