krasa / ArduinoLaserDistance

Arduino Uno + laser distance sensor + LCD

A project using:

• 50m/164ft Laser Distance Measuring Sensor (do not recommend this model, it has very tiny pcb pads for soldering RX/TX wires - different from the shop's photo, 100m model should be better)
• Arduino Uno
• I2C LCD
• button for tare

Used for a proper positioning of bales:

USB to UART - it does not shift rx/tx to 3.3V - it is better to use Logic Level Converter https://www.aliexpress.com/item/4000587260340.html (although maybe not necessary)
