An Arduino PLC project starts from your signal list and ends with an M-Duino or Ardbox running on site. Each project on this page shows the problem, how it is solved and the hardware it uses.
Four steps, from the first message to the first controller on site.
Inputs, outputs, sensors and what the system must do. A rough list is enough to start.
Run the closest simulator and break things on purpose: network cuts, faults, peaks.
Take a project pack or a recipe from the PLC Solution Library and adapt it.
We check the I/O count and the communications with you and you get a quote.
Industrial Shields engineers answer your questions from the first contact. The wiring and the start-up on site are done by your team or your integrator.
Seven projects with a real problem behind them. Each card links the simulator, the code and the installations where it already runs.
M-Duino · Weight · Conveyors
Pieces arrive mixed and each one has to reach the right exit, even when a sensor fails or a lane is full.
How it is solvedAn M-Duino weighs or reads each piece, tracks it along the belt and pushes it to its exit, with rejects and full lanes handled.
M-Duino · OK or KO · Traceability
Every unit has to be checked, and each result has to stay linked to its serial number.
How it is solvedAn M-Duino runs the steps, checks each window or wire and keeps one OK or KO record per part or serial number.
M-Duino · Modbus RTU and TCP
Drives, chillers and flow meters speak Modbus RTU, while the plant system needs one clean view over TCP.
How it is solvedAn M-Duino works as Modbus TCP slave and RTU master: it polls the RS-485 devices and exposes one register map.
M-Duino · Valves · Alarms
Temperature, humidity or pressure have to stay within limits, and someone has to know when they do not.
How it is solvedAn M-Duino reads the probes, drives valves, pumps or fans, raises alarms and logs the data.
M-Duino · MySQL · ERP
The plant needs reliable data from its lines, 24 hours a day, without replacing the machines.
How it is solvedM-Duino PLCs collect the data from each line and feed the database and the ERP.
Ardbox · Compact PLC
A single station needs a few checks or one room needs its own controller, and a large PLC would be too much.
How it is solvedOne Ardbox handles the local logic. In the factory case, it runs three quality checks on one Ardbox Relay.
Ardbox Analog · GPS · GPRS
You need to know where each vehicle is, and in a frozen food fleet, the temperature of the goods.
How it is solvedOne Ardbox Analog per vehicle reads the GPS position and, where needed, the temperature, and sends the data over GPRS.
Free material to design, test and supervise the project before you order anything.
Free course · 9 lessons
Your PLCs send data over MQTT or Modbus. This course shows how to turn that data into screens, alarms and history with Node-RED.
Tell us what the system must do and which signals it has. An Industrial Shields engineer will answer with the model and the next steps.
