Arduino LCD Metronome

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

Step 1: Parts

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
