a working breadboard version nor it is guaranteed not to fry your electrical system find great deals on ebay for led bar tachometer shop with confidence a simple 10 led tachometer circuit can be seen in the above diagram the circuit basically consists of two mains stages a monostable based tachometer using ic 555 and an led span class news dt 04 08 2014 span nbsp 0183 32 only thing i would need to add is the code for the bar graph led s correct also is serial println similar to system out println in java where the serial is the output and the mand follows also is serial println similar to system out println in java where the serial is the output and the mand follows to aid in reading the tachometer i created a label that has one column for each led and one row for each range the label is reproduced at right scaled to 300 dpi it should be 3 5 wide when printed span class news dt 04 07.

2012 span nbsp 0183 32 topic an led bar graph tachometer read 11914 times previous topic next topic hoff70 guest re an led bar graph tachometer 15 may 20 2012 05 24 pm the ir beam is just triggering the led pins on off i get a blink each time a hole in the disc es around it s actually not doing much but i wanted to start by having the ir beam trigger some kind of output i need to figure span class news dt 18 10 2005 span nbsp 0183 32 i know that this topic has been beat to death i m looking for a led bar graph tachometer circuit that will display the rpm like they do on the f1 and
