Bolt IoT device has 1 Analog pin. If I want to connect 2 Sensors( like 2 ldr ) then how it is possible? Answer please
You can connect the Bolt IoT module to another microcontroller with more number of ADC ports(such as in Arduino UNO) over UART.
You can then periodically send Analog values from the microcontroller to Bolt IoT module and retrieve them using APIs.
