hc sr04 module is there with me. one person extracted the Tx and Rx elements so that transmitter element can be fed with 40khz from 555 reciever is fed to a vu level meter . his demo shows led levels without Microcontroller usage. Question: if we remove the module..will there be false trigger and cause problem? |
