We successfully added 3 pads to the system and will try to accommodate 6 pads on one system because the nRF24L01+ system can support up to 6 active pipes on the multiceiver functionality. We are currently using channel 108 which is on the border of the free legal 2.4 GHz RF spectrum. This is to avoid any confusion and noise on the main 76 channel for 2.4 GHz which is going to be very saturated during demo day. Furthermore, with new materials coming in we can continue production up to 6 pads so we can split into 3 pads half and half for networked gaming hopefully. The hardware side is trying to implement DAC onto the central hub instead of the software side so that there could be a standalone aspect to the product but the practicality will be determined soon. The software system needs a few more tweaks to be able to support user input for songs and such.
We are pretty on track and that gives us room to try and tackle our stretch goals of creating a networked game for 2 different sets of drums. There will most likely have to be some encoding on the daisy to switch between the different contexts but otherwise there will be not much hiccup to upscale our product and we can find other ways to improve the sensitivity and accuracy of our product.
We just need to add our location calculations on the code to be able to determine the different types of sounds to play on the output.
