I am seeking an Arduino programmer with specific expertise in ESP32. The nature of this project requires the development of functionalities that can enable event scheduling in the ESP32 environment. Iot will send a schedule to the device. The schedule will look something like this CO2 2% 1 hour 20 minutes, CO2 0% 2 hour 0 minute, CO2 3% 1 hour 30 minute. The code already controls the CO2 levels to that percent. The problem we are having is running the schedule. So with the CO2 level there is a setpoint. That part works fine. You give it the setpoint and it maintains that level of CO2. However we need it to change the setpoint after x amount of time has elapsed and then change the setpoint again after another x amount of time has elapsed etc...We have a real time cl...
