The project we have decided to move forward with is a digital level using an accelerometer. The microcontroller will be an Atmel ATmega328. Depending on the inclination of the level when it is placed on a surface, indicator LEDs will be lit up in imitation of the bubble on an analog level. There will be a power switch on the side to turn it on and off, and it will be powered with lithium ion batteries.
Requirement checklist:
- 1 Sensor? Accelerometer
- 1 Actuator? Multiple LEDs
- Digital or Analog Processor? ATmega328
- Safe? Yes
- Schematic in progress using EagleCAD
- PCB will be correctly sized
- May have second PCB for LED assembly
- PCB designed from scratch
- >= 25% surface mount components: 100% will be surface mount
- Components will all be larger than 0603
- Will be built by our hands
- Enclosure will be 3D printed
