9‑in‑1 Multifunctional Expansion Board for Arduino UNO

Description:The 9 in 1 Mul­ti­func­tion Expan­sion Board Mod­ule (some­times it is called HALJIA) is a ver­sa­tile board that can be used for a vari­ety of Arduino projects. It includes 9 dif­fer­ent mod­ules:DHT11 humid­i­ty sen­sorLM35 tem­per­a­ture sen­sorBuzzerBright­ness sen­sorFull col­or LED mod­ule2‑way but­ton mod­ule2‑way LED mod­uleInfrared receiv­er mod­uleRotary poten­tiome­ter mod­uleThis board is ful­ly com­pat­i­ble with the Arduino UNO R3 and pro­vides a con­ve­nient way to add these 9 mod­ules to your projects with­out hav­ing to wire them up indi­vid­u­al­ly. It also has a cus­tom high-pin design to avoid short cir­cuits with the Arduino.Here are some exam­ples of projects that you can build with the HALJIA 9 in 1 Mul­ti­func­tion Expan­sion Board Mod­ule:A weath­er sta­tion that mea­sures tem­per­a­ture, humid­i­ty, and bright­nessA secu­ri­ty sys­tem that uses the infrared receiv­er mod­ule to detect motion and the buzzer to sound an alarmA robot that uses the rotary poten­tiome­ter mod­ule to con­trol its move­ment and the bright­ness sen­sor to avoid obsta­clesA traf­fic light sim­u­la­tor that uses the full col­or LED mod­ule to dis­play dif­fer­ent col­orsThe 9 in 1 Mul­ti-func­tion Expan­sion Board Mod­ule is a great choice for Arduino begin­ners and expe­ri­enced users alike. It can help you to save time and sim­pli­fy your projects.Images: Packing List:1 x Arduino Expan­sion Board Mul­ti­func­tion Expan­sion Board
