Picture of Arduino LCD Metronome

Metronomes can be expensive but with an Arduino and a few parts you can make an extensible metronome.

Step 1: Parts

- Arduino (any normal sized Arduino will be fine)
- The Arduino IDE and the knowledge to use it
- Lots of wires
- HD44780 LCD Display (I've used a 20x4 but a 16x2 will work fine)
- 3x 100K Ohm Resisors
- A rotary encoder -- must have a button
- 1M Ohm Resistor
- TDA7052 Amp
- Speaker
- 44K Ohm Potentiometer
- 100k Ohm Potentiometer
- 100nF non-polarised capacitor
- 100uF 16v electrolytic capacitor

Very good instructable, but What does a 44k ohm potentiometer do ??

Please where is the code link ?

This looks very cool and it gives me some ideas, for example automation of lights. This may help a person with timing values when writing the sketch for them lights.
Just wondering if you know of a way to have Arduino listen for, and store, the beat of a song playing?

At any rate I'm going to try this and thanks it's very cool, nice video too!

Really sorry it took me so long to reply.

Listening to something on the Arduino sounds fairly difficult I'm afraid. Analysing songs is generally quite a difficult and computationally expensive thing to do and I can't find any libraries for it. I'm not sure how you would even get a microphone talking to the arduino. Sorry

I'm really glad you liked it
