  • I just finished building this circuit and it did not work. After reading some of the other comments I decided to try a different circuit design. I found the website http://sodoityourself.com/max232-serial-level-converter/ helpful and I followed that schematic and it worked on the first try. If you want to get this circuit to work skip the 0.1uf capacitor between pins 2 and 6. Instead connect a 0.1uf capacitor between pin 2 and +5 volts. Then connect another 0.1uf capacitor between pin 6 and ground. As soon as I made that change it started working.

No public wish lists :(
