Tell us about yourself!
Thank you . However, in your video, I see you have used 3 different types of speakers (all 3 look different, at least from the mounting flanges)..Also your link is for 3W speakers... Is this OK ? the amp outputs 30W. If we turn up the volume wouldn't it damage the speakers ?
So connecting the speakers in series reduces the current drawn by them, I guess. Did you do any power calculations for this ?
Hi,Thanks for this! Could you share the web links to purchase the board and the speakers ?
No, its not 'only a shift register IC'. It uses the I2C (aka TWI) protocol. It has address jumpers, so you can connect up to 8 LCDs in parallel to the SAME 2 wires, which is not possible in a simple shift register arrangement.
