telemetry system for vehicles

This system is made to measure the speed of a wheel of a vehicle and the RPM of its engine. Then, it sends the values to an Android using bluetooth module HC-05. Finally, the Android sends the value to a firebase database. The Controller is Atmega2560 since it has more than one input capture unit peripheral.

Arduino nano version:-

Components:-

• 10 Kohm resistor
• 104 code ceramic capacitor
• Arduino Nano
• 7414 HEX schmitt trigger IC
• 16x2 LCD
• 9 volt battery

This version is used to measure the RPM of an engine in an international competition (shell eco marathon asia 2019). The project worked correctly during the whole competition.
