Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor ...

This project presents an Arduino based speed monitoring system where the RPM (revolutions per minute) of a DC motor is continuously displayed on a smartphone using Bluetooth communication. The Arduino ...

1 Buzzer 1 TFT LCD display for RPM, AMP and user CFG of Rotation (CW, CCW) 1 SD Card to LOG data (user inputs, Oveloads, etc) 2 Foot switches used for speed control. Custom home made shield: 1 Current ...

I have put some Arduino PCBs to manufacture according to my protoboard. I have made a 12V to 5V converter and used transistors to transmitt signal. On RPM pins i put one pin to GND and the second one ...

電子工作初心者がArduinoを使ってwifi環境センサを作ってみたので、その体験を書きます。Arduinoとは、家電の制御にも使われている小さいコンピュータ、通称マイコンの一種です。こいつを使ってデバイスを自作することができます。 モチベーション ある日 ...
