The Circuit Make Me Crazy......

People Said that i can do a PHD about that circuit.That has only 4Capacitors,1 IC, 1 serial port

I maid it nearly 50 times.

That circuit is USART circuit with max 232.

If you guys want to do robotics with communication with PC that is the circuit.

But that makes all thing a mess.

If you guys want to do it follow these tips.

1. Do not use a PC which leaks AC currents to the body.
2. Use a proper communication cable.
3. Make this circuit in separate PCB.
4. If you guys have communication problem, please check the IC.

If you guys still have trouble contact me.
