About this app
Build and test electronic circuits on your phone with DevreLab: no burnt parts, no fear of short circuits.
Batteries, resistors, LEDs, transistors, relays, motors, sensors and an Arduino UNO: place them on the workbench, connect them with wires and the circuit works instantly. See where the current flows with moving yellow dots, measure with a multimeter, and when something burns out, learn why.
WHAT'S INSIDE
• 50 part types: resistors, capacitors, LEDs, RGB LED, diode and zener, switches and push buttons, NPN/PNP transistors, MOSFET, relay, thyristor and triac, lamp, DC motor, servo, buzzer, LDR, NTC/PTC, LM35, PIR, ultrasonic distance sensor, joystick, LCD and 7-segment displays
• Breadboard: real holes and strips, just plug the legs in
• 63 ready-made example circuits, from lighting an LED to a smart home panel, with step-by-step guides
• Virtual multimeter: measure voltage, current and resistance; connect the ammeter wrong and its fuse blows
• Arduino UNO: write code on your phone, upload it to the board and watch the serial monitor (a simplified subset of the Arduino language)
• Vehicle and self-balancing robot: let your circuit drive a car or a robot that balances itself
• An info booklet for every part: pinout, limits, correct use
• Current animation and slow motion: watch a capacitor charge in slow motion
MADE FOR LEARNING
Inspired by the lab kits used in electrical-electronics and automation classes in vocational high schools. Mistakes are explained in plain words, like "LED burned out: add a series resistor". Part values are based on manufacturer datasheets.
YOUR CIRCUITS ARE SAFE
• Your circuits are saved automatically, so you continue where you left off
• Optionally link an account: your circuits are backed up to the cloud and open on another phone
• Share a circuit with a friend as a file
• Works fully offline
NO ADS. No usage statistics are collected. We never ask for your real name, school or phone number.
IMPORTANT: DevreLab is a simulation. Real circuits may behave differently; when working with mains voltage (230 V), always work under adult or teacher supervision and follow safety rules.
Designed for ages 13 and up.

What’s new
New parts: transformer, LM2596 and MT3608 DC-DC modules, L293D motor driver, logic ICs (74HC00/04/14/595, CD4511, CD4017), stepper motor + ULN2003, 18650, coin cell and lead-acid battery.
Code editor: duplicate line, select line, Format, for/while templates, parameter hints; see the running line with ▶ Watch.
Chips, ESP32, Nano, HC-SR04 and ULN2003 now have the same pin order as the real parts.
163 example circuits in total.
