TINKER PIEDESIGN IN INDIA

Smart street light

A light sensor and a relay: when it gets dark, the lamp turns on by itself.

What you need

Wiring

Light sensor: AO → P10. Relay module: IN → S1 (the lamp is switched by the relay).

Step by step

  1. Open Smart street light in TinkerPie Studio. It opens as blocks.
  2. Wire it: Light sensor: AO → P10. Relay module: IN → S1 (the lamp is switched by the relay).
  3. Press Run to try it in the simulator. Use the sliders and buttons under the board picture to test it.
  4. Connect TinkerPie with a USB-C cable in Chrome or Edge, press Connect, then Download. Or, with Studio started from the TinkerPie launcher on your computer, open the Arduino C++ tab and press Build & Flash.
  5. Change something: a colour, a number, a sound. Then run it again.

The code

This is the program the blocks make. The same program runs in the simulator and on the board.

JavaScript
basic.forever(function () {
  if (sensors.lightSensor(Pin.P10) < 30) {
    outputs.relay(Pin.S1, true);
    led.fill(colors.rgb(60, 45, 20));
  } else {
    outputs.relay(Pin.S1, false);
    basic.clearScreen();
  }
  basic.pause(500);
});
Arduino C++ (TinkerPie library)
// Smart street light
// Arduino C++ made by TinkerPie Studio from the blocks. Board: TinkerPie V1 (ESP32-S3).
// Arduino IDE: install the TinkerPie library (Studio menu > Arduino library), then Tools > Board > ESP32S3 Dev Module,
// USB CDC On Boot: Enabled, Flash Size: 16MB, Partition Scheme: 16M Flash (3MB APP/9.9MB FATFS), PSRAM: OPI PSRAM.
#include <TinkerPie.h>
using namespace tinkerpie;

void setup() {
  tinkerpie::begin();
  basic::forever([]() {
    if (sensors::lightSensor(Pin::P10) < 30) {
      outputs::relay(Pin::S1, true);
      led::fill(colors::rgb(60, 45, 20));
    } else {
      outputs::relay(Pin::S1, false);
      basic::clearScreen();
    }
    basic::pause(500);
  });
}

void loop() {
  tinkerpie::loop();   // runs the forever blocks and handles events
}
