Introduction
This is an automatic import from our previous community platform. Some things can look imperfect.

The goal of this project is to automatically sort resistors in 66 different tubes, 60 tubes for the E12-series: 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82 ohm and six tubes for unknown and out of category resistors. It will be controlled by a PICAXE 28X1 chip. To measure the resistance a voltage divider is read with ADC by the picaxe chip (different compare-resistors is connected with relays: 100Ω,1kΩ,10kΩ,100kΩ,1MΩ). A belt drive will feed the resistors and a servo will hold them while ...

This is still in construction.
