Back in Arduino-land, here’s a test of waking up from deep-sleep, reading the BME280 and then sending it to adafruit.io before going back to sleep. We read the sensor data before starting up the wifi, so the sensor isn’t heated up from the ESP32S2 too much. Quiescent current is 85uA, we think most of that is the AP2112 regulator. We removed the LC907203 battery monitor for now, it seems to have spikey ADC reads that kick in every second or so (which is fine but is a little confusing) – video.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
