Today we are going to make a simple portable Ultrasonic based Digital Scale, but there is a small twist in it, we are going to make this project in Free-Form, without using jumpers or pcb, instead we will use thick copper rods, so lets get started!
1. Arduino Nano
2. Ultrasonic Sensor (HC-SR04)
3. 0.96” OLED
4. 0.8mm Copper Wire
5. 0.6mm Copper Wire
1. Soldering Iron
2. Soldering Wire
3. Helping Hands
