A rechargeable portable weighing scale, to weigh your bags before going anywhere and anytime.
- Rechargable - It is a rechargable device, so no need to worry about batteries.
- Light weight - Easy to carry and move around.
- Small size - Can be easily placed at any place.
I built this because a lot of times, when people leave for their flights with overweight, they need to loose their items or pay fine which is not good. So, with this they can easily measure the weight and adjust accordingly.
I learnt how a load cell works and how a HX711 IC is used to read from the load cell and provide result to the microcontroller.
