computer organization and computer architecture

I have 2 devices that need to be enhanced. They are a Raspberry Pi and Arduino. One transmits data to the other. But I need it to be better engineered. Need to add encapsulation to the devices and add an accelerator and one device needs to be able to connect via Bluetooth to multiple devices and manage them.

The battery-powered mobile device is built on the ESP32 architecture. The device wakes up every hour (deep sleep), receives data from the sensors, sends it via the GSM channel via the SIM800 module via the MQTT protocol to the server and goes back to sleep. There is a sample code. All sensors are connected via the i2c or 1-wire bus: ADC1115 (2 pcs.), BME280 (2 pcs.), DS18B20. Basic requirements...

Provide a schematic design for a 556 dual timer IC base circuit to be triggered by a phototransistor with the result that two simultaneous 5v pulses are generated.

You must pass a difficult test to work with me. You do *not* need an Arduino. You do *not* need an ESP32. You will normally work 1 hour/day for 10 US dollars/hour. But, I presume Freelancer will pay you 9 US dollars/hour after they deduct their 10% fee. You will normally work 20 days each month for 9 US dollars/hour. Therefore, you will normally earn 180 US dollars/month. If you are very in...

I have an Arduino MKR1000 monitoring a power failure system. When the power fails, the MKR registers a change of state in the system's "off-line" LED (changes state to on, which is captured by a photo-resistor. The Arduino then sends an power failure alert via wifi. May need help cleaning up the existing code, but for now what is most pressing; building code that performs a self-di...
