The heart of the project is Attiny1614 which can be programmed with [UPDI Programmer](https://easyeda.com/wagiminator/y-updi-programmer). The source code of the programmer can be found [here](https://github.com/ElTangas/jtag2updi). The arduino core for the MCU can be found [here](https://github.com/SpenceKonde/megaTinyCore). It has 16384 bytes flash, 2048 bytes RAM and 256bytes...
Simple tachometer, based on arduino nano.
7 digit display based on ULN2003 and 74HC595
2. Mode switch. Between Hz and RPM.
3. Point position. Chose how many digits after point will be displayed.
This tachometer uses ATmega328p Input capture register of Timer Counter #1.
Also I used a lot of float math in this code. ToDo is to move all math into static point to imp...
Hello friends welcome to Techno-E-Solution.
Here is the circuit diagram for Arduino Tachometer.

This is a small pcb that is designed to be used on an electric go-kart to display a stopwatch, motor RPMs, and cart speed as well as record this data on an SD card with a time stamp for analysis. The project is Arduino based and is ran off of 7-59 VDC or directly from a 5V source through any of the 5V or VIN pins on the data logger shield (this is not a protected input). It is designed to have w...
