I am looking for help with modifying code which I found on internet. I need too make it a little bit different. I am not experienced in this area so I am willing to pay for someone to do it for me. So what I am doing is vehicle gauge, which would show car speed, RPMs and engine coolant temperature. I want those parameters to change one another on display by pressing swich or if its not possible, just show them on screen at same time. I am using Arduino Uno, Oled 0,96 inch 128x64 I2C screen and MCP2515 CAN Bus to SPI module.
can you post the sketch you found on the internet?
Or the link where he is?
