EdgeBox-ESP-100 Getting Start with Arduino

Edgebox-ESP-100​

EdgeBox-ESP-100 is an ESP32-based controller designed for lightweight automation solutions. It supports analog input, effectively monitoring and controlling in a remote environment, ideal for PID control loops, logic sequencing control, or a gateway with flexible wireless and field sensors expansion.

Besides EdgeBox-ESP-100, We also have the other 2 Edge products for different solutions in the Edge family, powered by Raspberry Pi. To help you understand the differences deeply and choose the most suitable part for your projects, please refer to the Seeed Studio Edge Series Page.

It offers isolated CAN, RS485 Fieldbus connections, and rich IO resources for extensive facilities and sensors input, for both digital and analog signals. It is perfectly satisfactory to the PLC and field automation applications.

Since it contains on-chip Wi-Fi and BLE functions, and also includes a 4G LTE module Cellular, EdgeBox-ESP-100 can be utilized to establish an industrial gateway, enabling the original PLC to connect the network or cloud.

This portable box comes with rugged hardware, an electrical design, and an aluminum alloy enclosure, by which it maintains its function in a wide temperature range and provides high surge and short circuit protection, for diverse deployment methods based on your business.

Code​

Here is the code for cycling through all the Solenoid, Please copy the code to the Arduino IDE Code editor

void setup() {
  //setup DO pins to output mode
  pinMode(DO0, OUTPUT);
  pinMode(DO1, OUTPUT);
  pinMode(DO2, OUTPUT);
  pinMode(DO3, OUTPUT);
  //setup DO pins default to Logic LOW
  digitalWrite(DO0, LOW);
  digitalWrite(DO1, LOW);
  digitalWrite(DO2, LOW);
  digitalWrite(DO3, LOW);
}

void loop() {
  //Switch on DO0 and Swith off DO3
  digitalWrite(DO0, HIGH);
  digitalWrite(DO3, LOW);
  delay(2000);

  //Switch on DO1 and Swith off DO0
  digitalWrite(DO0, LOW);
  digitalWrite(DO1, HIGH);
  delay(2000);

  //Switch on DO2 and Swith off DO1
  digitalWrite(DO1, LOW);
  digitalWrite(DO2, HIGH);
  delay(2000);
  
  //Switch on DO3 and Swith off DO2
  digitalWrite(DO2, LOW);
  digitalWrite(DO3, HIGH);
  delay(2000);
}

Upload code​

  • STEP 1: Now please plug-in the USB-To-Serial adptor your PC and the connection of Edgebox-ESP-100 with USB-To-Serial convertor should set to download program mode.
note

Do not Power Up the Edgebox-ESP-100 until next step

  • STEP 2: Power up the Edgebox-ESP-100

  • STEP 3: Select Board and PORTS

  • STEP 3-1: Open the Board and Port selection window

pir
  • STEP 3: Select Boards and PORTS from the Board and Port selection window in this case we can put edgebox into the search bar and select Edgebox-ESP-100 as the board, and select Port according to your USB-to-Serial adaptor. Then press OK to comfirm.
pir
  • STEP 4: Press upload code button to upload the code.
pir
