I was approached by a close friend in need of an Arduino setup. I&#39;m a programmer, but the hardware and this GPIO stuff is a little confusing since I&#39;ve never touched it before. The gist is this: Using an Arduino, the user wants to control a small lift that already has a control pad (so we can hijack the up and down buttons using a relay of some sort). They want to be able to use up and down buttons to change 2 variables that show on a small display and those variables control how long the platform stays in the up position, and the other is how many times the platform goes up and down. I&#39;ve compiled a small outline below. any help is appreciated and I&#39;ll answer any questions.</p> <p>&#x200B;</p> <p>Goal</p> <p>Allow a provided platform to be raised and lowered with specified, variable pauses at apogee for a specified, variable number of cycles at a specified, static height. </p> <p>Variables </p> <ul> <li>Repetitions</li> <li>Delay</li> </ul> <p>Buttons</p> <ul> <li>Repetition up</li> <li>Repetition down</li> <li>Delay up</li> <li>Delay down</li> <li>E-Stop</li> <li>Start</li> </ul> <p>Output</p> <ul> <li>Relay-platform up</li> <li>Relay-platform down</li> <li>Display-Cycles remaining</li> <li>Display-Delay</li> </ul> </div><!-- SC_ON --> &#32; submitted by &#32; <a href="https://www.reddit.com/user/BigDaddy850"> /u/BigDaddy850 </a> <br/> <span><a href="https://www.reddit.com/r/ArduinoProjects/comments/10j44vh/beginner_here_need_a_parts_list/">[link]</a></span> &#32; <span><a href="https://www.reddit.com/r/ArduinoProjects/comments/10j44vh/beginner_here_need_a_parts_list/">[comments]</a></span></content><id>t3_10j44vh</id><link href="https://www.reddit.com/r/ArduinoProjects/comments/10j44vh/beginner_here_need_a_parts_list/" /><updated>2023-01-23T04:48:44+00:00</updated><published>2023-01-23T04:48:44+00:00</published><title>Beginner here... need a parts list</title></entry><entry><author><name>/u/Big_Citron7615</name><uri>https://www.reddit.com/user/Big_Citron7615</uri></author><category term="ArduinoProjects" label="r/ArduinoProjects"/><content type="html"><!-- SC_OFF --><div class="md"><p>Hi there, I was going to make a project in which I&#39;m using an electromagnet.

However, my data is always a constant (recording at approx 300) with no change for muscle contraction. Looking at other online videos, the values seem to &#39;normally&#39; jump dramatically from 60 to over 100.</p> <p>My code is incredibly basic;</p> <h1>define SENSOR_PIN 1</h1> <p>// Integer for sensor value</p> <p>int sensorValue;</p> <p>void setup() {</p> <p>// Set up serial port</p> <p>Serial.begin(9600);</p> <p>}</p> <p>void loop() {</p> <p>// Read sensor value</p> <p>sensorValue = analogRead(SENSOR_PIN);</p> <p>// Print value to Serial Monitor</p> <p>Serial.println(sensorValue); }</p> <p>My circuit is also very basic (image in the comments).</p> <p>I have also tried the same code and circuit with an AD8232 ECG board with similar results.</p> <p>What the hell am I doing wrong?
