electronics design will be easier if we use some electronics design software, for example protel, altium, eagle, proteus, etc. the best electronics design software is depend on us, but the more user friendly and complex step from schematic/circuit design, pcb design, and until simulation and reliability to the drilling machine, will be the best software.

electronics design including

1. schematic

2. pcb design layout

3. simulation and programming (if needed)

4. prototype design (pcb circuit, drilling, soldering)

5. testing
