oscilloscope

Hi everyone - I am very new to B4A (competent in VB) and am struggling to implement a 3 channel scope (to display ECGs) from a Buetooth data stream from an Arduino with HC-06 and an Analog front end. I know my Arduino side it working well and sends each channel as text with a header "P1 " then...

Low frequency oscilloscope for PC using Arduino Uno or Nano. The input is to pin A0 of the Arduino which connected to PC via USB .Bandwidth up to 5KHz. The sampling is done by the Arduino ADC in a speed of about 36K sampling per sec. The Arduino software is mostly in C code in purpose to speed...

OLED low frequency oscilloscope, bandwidth is DC to 1000Hz. Max sampling rate is 16000 samples per second. An oscilloscope with these specifications has limited use, but it is a good exercise in using OLED display. rWire lib is used for I2C. Inline c used to increase speed of I2C to 400KHz...

Low frequency oscilloscope for Android using Arduino Uno or Nano, frequencies up to 5KHz. The software for Android is in B4A. The Arduino connected to Android device via USB OTG cable. The sampling is done by the Arduino ADC in a speed of about 20K sampling per sec. The Arduino software is...
