Dalam tulisan ini rotasi per menit (selanjutnya disingkat RPM) diukur menggunakan Arduino dengan memanfaatkan sinyal pulsa yang dibangkitkan oleh sensor. Sensor RPM yang digunakan telah terintegrasi pada anemometer untuk kebutuhan pengukuran kecepatan angin. Agar RPM dapat diukur maka dapat digunakan perangkat keras Real Time Clock sehingga variable waktu juga diketahui.

Measuring AC Voltage Using Arduino: Maximum Voltage Method
A voltage sensor is used to measure AC and DC voltage, however the use of measurement algorithms are different. The DC voltage is constant so that the measurement is relatively easy, in contrast with AC voltage that varies according to a sine wave form and has a voltage magnitude in the positive and negative quadrant. AC effective voltage magnitude can be determined if the maximum voltage / peak known. By using the right algorithms and mathematical equations, the maximum value and the effective value of the AC voltage can be found.
