The HY Project foresees these regulations. In response, the EU has recently introduced regulations stipulating that there must be an acoustic vehicle alert system (AVAS) in all-new electric vehicles by 2021. With the number of electric and hybrid vehicles in use on the rise, it has become clear that despite their environmental advantages, the fact that the vehicles don’t make any sound is dangerous to pedestrians, who cannot hear them incoming. The HY Project involves a device that attaches to an electric vehicle and emits a specific sound frequency, which stimulates plant growth and can be heard by nearby pedestrians. Setting this to restart will help keep processing load down on your computers CPU.Spotted: Engineers at The Electric Factory and Toyota Uruguay founded a project aiming to make electric vehicles safer for pedestrians while aiding the environment at the same time. In Sustain mode, every keystroke will add another instance of the sample to the playlist on the far right side of the Soundplant window. Under the 'KEYMODE' area we are going the select 'restart' instead of 'sustain.' Placing this in restart mode will restart the sample and only play ONE instance of the sample. This is important to notice because we will be applying certain settings to each key so we want to make sure we have the correct one highlighted. When you drag the sample into Q, you will see it becomes highlighted with a purple glow around the key. For this examples, we're using 'Q' to start. You can simply drag and drop the samples into the Soundplant, directly onto the key of your choice. Since our code was set up to work on only the keys determined in the const char KEY_MAP constant, we are going to start with the letter 'Q.' This KEYMAP is what we will load to make sure all the samples are loaded each time we open the software. Okay here is the fun part! We are going to bring in prepared samples into the Soundplant software to start to layout our KEYMAP. You will need to make sure you select the correct board and port for the second one as well. Once the first one works, repeat the process with the second Touch Board by uploading Soundplant_BCTB_2of2 onto the second Touch Board. If all is well, then they will blink for a few seconds, and then go off.īefore we get to the Soundplant software, touch a few of the electrodes on the Touchboard and you should see the LED's light up. Hit this button and you will see ' Uploading.' at the bottom, and you will see 4 LED's on the touch board flash (L, Tx, Rx). If there are no errors it will say 'done compiling' in the bottom left of the window. The check mark is used to verify the code for any errors. One with a check mark and one with arrow. Up the left hand corner of the window are two circles: ino file Soundplant_BCTB_1of2 onto the first touch board. Once the board is connected, and is being read properly, lets load. This process is the same for both boards, just with different files for each board. This will assign Electrodes E0-E11 on the Bareconductive Touch Board 2 of 2. This organization was to keep the samples organized on ONLY the letter keys of the keyboard to keep things simple. The second constant we will change is const char KEY_MAP = **** This will help keep the performance of this digital instrument a little bit more organic and react like a traditional acoustic instrument.Ģ. The first constant we will change is const bool HOLD_KEY = true we are going to change 'true' to 'false'īy changing this to 'false', it will send a single (on/off) keystroke to Soundplant. In Soundplant_BCTB_2of2, under // keyboard behaviour constants we are going to change two constants.ġ. This instrument will be used with the children's individual conductive shapes (cardboard wrapped in aluminum foil). Unfortunately, we can no longer do this because of COVID-19. In normal circumstances, the children will trade and share instruments. This project is part of a socially distanced enrichment project for an elementary school music teacher. Why are we using Bareconductive Touch Boards instead of two keyboards? Here is a link that explains how the Bareconductive Touch Boards use capacitive touch to send signals. Anytime you touch a sensor in the Bareconductive board, it will send a 'keystroke' to Soundplant and will play the assigned sample. We will be 'fooling' the computer into reading the Bareconductive boards as regular typing keyboards. We will code this instrument using Arduino (download link below). This 24 input digital instrument will be used with Soundplant (download link below). The program I am involved in is "GoSteam."

This project is a documentation for a work project through my job at CEISMC (Center of Education Integrating Science, Mathematics, and Computing).
