Yes Johnny!!
Its is a maglev, I understand the concept of how the maglev work but we are actually suppose to build a feeedback circuit which is suppose to interact between a hall effect sensor and a voltage amplier circuit.
I have completed the voltage amplifier circuit, but the problem I have is the feed back circuit which is suppose to be consist of a micro-controller telling the voltage amplifer to increase or decrease the voltage based on the distance of a magnet and the hall effect sensor...
Voltage amplifier circuit was easy coz details can be located through out the web, but I cant find anything relating to feed back circuit that works as stated above...
Hope u get what I mean... Thanks in advance!!
