The operator sets the first potentiometer to the desired speed and the second potentiometer to the desired off/on time ie off for say 3secs then on for say 1.5 secs, note this must be variable by the potentiometers. Now i had this designed and prototypes built in the past and it all failed as the 2 potentiometers interacted with each other and caused a very unreliable output, i think they fed off ...

ok thanks Hi I have a ItsyBitsy M0 Express. I want to connect a RS485 Halfduplex with just the 2 wires A and B. I have connected a converter wich makes out of the differntial signal of the AB RX/TX. I have just left the MISO and MOSI pins. The connected part just sends 2 bytes after it received 2 bytes from ItsyBitsy, can you send me just such an INO code? Let me know how much it costs. Thanks Fra...

The aim of this project is to develop a system that allows the user to record an audio clip and then play it back with different types of filters to manipulate the audio signal. Such a device would serve as a ‘fun-toy’ for kids to listen to themselves differently. The system will consist of a DSP/Microcontroller that will accept input audio signals from the user. During the recording ...
