Android Multimeter Premium 2.0.0
In the new version of multimeter 2.0.0 you can find new functions such as serial monitor and possibility of communication via USB cable (OTG connection) or Bluetooth. You can use the circuit of the previous versions but if you want to use USB connection (OTG cable) you will have to upload the sketch with the version of code 2.0.0. At the moment you will only have to upload the sketch and you will not have to make any modifications to be able to use the circuit of the previous version. But if you want to use both connections with the same sketch 2.0.0 you will have to connect Rx pin and Tx pin of the bluetooth module to the Rx and Tx pins of the arduino. The Rx pin of the bluetooth module must be connected to the Tx pin of the arduino and the Tx pin of the bluetooth module to the Rx of the arduino. The sketch with the lower version of 2.0.0 can not use USB connection. To use USB connection your smartphone must have that option (not all smartphones support this mode of connection, although today most smartphone support it).
USB connection
At the moment I tried arduino uno, arduino nano and ESP32. To be able to connect our arduino to the smartphone we will need an OTG cable as you can see in the image below. Do not forget: in the menu you must choose USB connection.
After uploading the sketch 2.0.0 and connecting the OTG cable you can use the multimeter without the need for a bluetooth module.
Serial monitor
To use the serial monitor, just open Serial monitor in the app menu and from your arduino, send data using the “Serial.println (” DATA “) command. You can also send data with the help of serial monitor to your arduino.
Puedo ayudar para Turco.
A que te refieres?
Saludos, Tengo un Samsung A30 creo q’si tiene función otg aunque no lo he probado pero me gustaría tener información sobre el multímetro con esa opción como te comente en una pregunta anterior lo necesito para trabajar en el área automotriz. Gracias…!!!
Si tiene el otg entonces no habrá problema
Holaáaaa mi pregunta es q si el costo por la app es se 69 pesos mexicanos????
no estoy seguro cuanto es en dinero mexicano, yo pongo precio en evro
hola puedo usar un arduino mini, me interesa solo usarlo por otg
hola, arduino mini no tiene aref pin por eso no va a funcionar
Hello,
Would you have the oscilloscope probe circuit? Which connector etc..
Thanks
Hello,
The app is great. My request will be .. Electronic material testing on the application (Transistor Tester LCR Diode Capacitance ESR meter PWM Square wave Signal Generator) would be perfect. .Thank you from now. (for my bad english, sorry. because of the translation :))
please would you please send gerber file i appreciate that great jog
