Hi Yaseming. Azoteq's 9 channel projected capacitive prox and touch controller IC (the IQS333) was used. Please find more information here: www.azoteq.com/product/iqs333/
Hi, I'm trying to figure out how the 7seg displays are connected in this board... Do you have a data sheet for this sensor? Also will you be able to provide the code that you used for the example in the video? Thank you very much
