Human: V2 uploaded! ERC DRC error free. Created this design for a teacher that needed an all-round PCB with an Arduino. It's a proto board for an Arduino course at my school. Students use it to practice Arduino C. It contains: * i2c barometer 3v3 version * 2 Potmeters - analog in * 2 digital switches - digital in * i2c LCD - for showing values * RGB led - can be controlled * 2x i2c expansion ports Parts needed: 1x Arduino nano 2x BS170 transistor 2x pressure switches 1x LM7805 2x 10uf caps 2x pressure switch some resistors 1x Barometer https://aliexpress.com/item/I2C-SPI-BMP280-3-3-Digital-Luchtdruk-Hoogte-Sensor-Hoge-Precisie-Atmosferische-Module-Vervangen-BMP180/32951657779.html?spm=a2g0z.search0204.3.2.78931d67CoxktA&s=p&ws_ab_test=searchweb0_0%2Csearchweb201602_8_10065_10068_10843_319_10059_10884_317_10887_10696_321_322_453_10084_454_10083_10103_10618_10304_10307_10820_10301_10821_537_536%2Csearchweb201603_52%2CppcSwitch_0&algo_pvid=c52441ca-817a-49f9-9a63-f4eb1069c797&algo_expid=c52441ca-817a-49f9-9a63-f4eb1069c797-0 1x RGB led common cathode https://aliexpress.com/item/50PCS-5000MCD-10mm-Diffused-RGB-LED-4Pins-Common-Anode-50Degree-Free-shipping/1770039061.html?spm=a2g0z.search0204.3.9.b77e317dTRHXC6&s=p&ws_ab_test=searchweb0_0,searchweb201602_8_10065_10068_10843_319_10059_10884_317_10887_10696_321_322_453_10084_454_10083_10103_10618_10304_10307_10820_10301_10821_537_536,searchweb201603_52,ppcSwitch_0&algo_expid=0a4e4059-2102-479f-aafc-1c3fcedca739-1&algo_pvid=0a4e4059-2102-479f-aafc-1c3fcedca739
