I have been working on an Arduino based call and message project which I am following from this link https://circuitdigest.com/microcontroller-projects/call-and-message-using-arduino-sim900-gsm. This project uses a membrane keypad for inputting the phone number and etc., but I intend to use a TTP229 16 channel Touch sensor module.

I need help in taking input from the touchpad rather than the keypad. As I need to submit the project within a month it is my humble request if someone can help. Thanks for replying!

  • how does the touch panel communicate with the arduino? ..... what code are you using? ..... what problems are you facing? – jsotola Jan 26 '19 at 23:00
