5V ESP8266 WiFi Relay Module 37 in 1 Sensors Kit for Arduino using minimal components for reliable

using minimal components for reliable self-oscillation - easy to understand

A0) AND to GND through a fixed resistor (10kOhm-47kOhm) Fixed Resistor Between Flex Sensor Pin 2 and GND (forms voltage divider) Analog Output Read at the junction of Flex Sensor Pin 2 and the fixed resistor Tip: Choose a fixed resistor value close to the flex sensor's nominal flat resistance (~25 kOhm) for maximum sensitivity and voltage swing across the ADC range

Arduino IDE Compatible: Fully programmable via Arduino IDE with the ESP8266 board package - use familiar libraries
